Climate scientists: concept of net zero is a dangerous trap

Sometimes realisation comes in a blinding flash. Blurred outlines snap into shape and suddenly it all makes sense. Underneath such revelations is typically a much slower-dawning process. Doubts at the back of the mind grow. The sense of confusion that things cannot be made to fit together increases until something clicks. Or perhaps snaps.

Collectively we three authors of this article must have spent more than 80 years thinking about climate change. Why has it taken us so long to speak out about the obvious dangers of the concept of net zero? In our defence, the premise of net zero is deceptively simple – and we admit that it deceived us.

The threats of climate change are the direct result of there being too much carbon dioxide in the atmosphere. So it follows that we must stop emitting more and even remove some of it. This idea is central to the world’s current plan to avoid catastrophe. In fact, there are many suggestions as to how to actually do this, from mass tree planting, to high tech direct air capture devices that suck out carbon dioxide from the air.

The current consensus is that if we deploy these and other so-called “carbon dioxide removal” techniques at the same time as reducing our burning of fossil fuels, we can more rapidly halt global warming. Hopefully around the middle of this century we will achieve “net zero”. This is the point at which any residual emissions of greenhouse gases are balanced by technologies removing them from the atmosphere.

This is a great idea, in principle. Unfortunately, in practice it helps perpetuate a belief in technological salvation and diminishes the sense of urgency surrounding the need to curb emissions now.

We have arrived at the painful realisation that the idea of net zero has licensed a recklessly cavalier “burn now, pay later” approach which has seen carbon emissions continue to soar. It has also hastened the destruction of the natural world by increasing deforestation today, and greatly increases the risk of further devastation in the future.

To understand how this has happened, how humanity has gambled its civilisation on no more than promises of future solutions, we must return to the late 1980s, when climate change broke out onto the international stage.

Steps towards net zero

On June 22 1988, James Hansen was the administrator of Nasa’s Goddard Institute for Space Studies, a prestigious appointment but someone largely unknown outside of academia.

By the afternoon of the 23rd he was well on the way to becoming the world’s most famous climate scientist. This was as a direct result of his testimony to the US congress, when he forensically presented the evidence that the Earth’s climate was warming and that humans were the primary cause: “The greenhouse effect has been detected, and it is changing our climate now.”

If we had acted on Hansen’s testimony at the time, we would have been able to decarbonise our societies at a rate of around 2% a year in order to give us about a two-in-three chance of limiting warming to no more than 1.5°C. It would have been a huge challenge, but the main task at that time would have been to simply stop the accelerating use of fossil fuels while fairly sharing out future emissions.

Four years later, there were glimmers of hope that this would be possible. During the 1992 Earth Summit in Rio, all nations agreed to stabilise concentrations of greenhouse gases to ensure that they did not produce dangerous interference with the climate. The 1997 Kyoto Summit attempted to start to put that goal into practice. But as the years passed, the initial task of keeping us safe became increasingly harder given the continual increase in fossil fuel use.

It was around that time that the first computer models linking greenhouse gas emissions to impacts on different sectors of the economy were developed. These hybrid climate-economic models are known as Integrated Assessment Models. They allowed modellers to link economic activity to the climate by, for example, exploring how changes in investments and technology could lead to changes in greenhouse gas emissions.

They seemed like a miracle: you could try out policies on a computer screen before implementing them, saving humanity costly experimentation. They rapidly emerged to become key guidance for climate policy. A primacy they maintain to this day.

Unfortunately, they also removed the need for deep critical thinking. Such models represent society as a web of idealised, emotionless buyers and sellers and thus ignore complex social and political realities, or even the impacts of climate change itself. Their implicit promise is that market-based approaches will always work. This meant that discussions about policies were limited to those most convenient to politicians: incremental changes to legislation and taxes.

Around the time they were first developed, efforts were being made to secure US action on the climate by allowing it to count carbon sinks of the country’s forests. The US argued that if it managed its forests well, it would be able to store a large amount of carbon in trees and soil which should be subtracted from its obligations to limit the burning of coal, oil and gas. In the end, the US largely got its way. Ironically, the concessions were all in vain, since the US senate never ratified the agreement.

Postulating a future with more trees could in effect offset the burning of coal, oil and gas now. As models could easily churn out numbers that saw atmospheric carbon dioxide go as low as one wanted, ever more sophisticated scenarios could be explored which reduced the perceived urgency to reduce fossil fuel use. By including carbon sinks in climate-economic models, a Pandora’s box had been opened.

It’s here we find the genesis of today’s net zero policies.

That said, most attention in the mid-1990s was focused on increasing energy efficiency and energy switching (such as the UK’s move from coal to gas) and the potential of nuclear energy to deliver large amounts of carbon-free electricity. The hope was that such innovations would quickly reverse increases in fossil fuel emissions.

But by around the turn of the new millennium it was clear that such hopes were unfounded. Given their core assumption of incremental change, it was becoming more and more difficult for economic-climate models to find viable pathways to avoid dangerous climate change. In response, the models began to include more and more examples of carbon capture and storage, a technology that could remove the carbon dioxide from coal-fired power stations and then store the captured carbon deep underground indefinitely.

This had been shown to be possible in principle: compressed carbon dioxide had been separated from fossil gas and then injected underground in a number of projects since the 1970s. These Enhanced Oil Recovery schemes were designed to force gases into oil wells in order to push oil towards drilling rigs and so allow more to be recovered – oil that would later be burnt, releasing even more carbon dioxide into the atmosphere.

Carbon capture and storage offered the twist that instead of using the carbon dioxide to extract more oil, the gas would instead be left underground and removed from the atmosphere. This promised breakthrough technology would allow climate friendly coal and so the continued use of this fossil fuel. But long before the world would witness any such schemes, the hypothetical process had been included in climate-economic models. In the end, the mere prospect of carbon capture and storage gave policy makers a way out of making the much needed cuts to greenhouse gas emissions.

The rise of net zero

When the international climate change community convened in Copenhagen in 2009 it was clear that carbon capture and storage was not going to be sufficient for two reasons.

First, it still did not exist. There were no carbon capture and storage facilities in operation on any coal fired power station and no prospect the technology was going to have any impact on rising emissions from increased coal use in the foreseeable future.

The biggest barrier to implementation was essentially cost. The motivation to burn vast amounts of coal is to generate relatively cheap electricity. Retrofitting carbon scrubbers on existing power stations, building the infrastructure to pipe captured carbon, and developing suitable geological storage sites required huge sums of money. Consequently the only application of carbon capture in actual operation then – and now – is to use the trapped gas in enhanced oil recovery schemes. Beyond a single demonstrator, there has never been any capture of carbon dioxide from a coal fired power station chimney with that captured carbon then being stored underground.

Just as important, by 2009 it was becoming increasingly clear that it would not be possible to make even the gradual reductions that policy makers demanded. That was the case even if carbon capture and storage was up and running. The amount of carbon dioxide that was being pumped into the air each year meant humanity was rapidly running out of time.

With hopes for a solution to the climate crisis fading again, another magic bullet was required. A technology was needed not only to slow down the increasing concentrations of carbon dioxide in the atmosphere, but actually reverse it. In response, the climate-economic modelling community – already able to include plant-based carbon sinks and geological carbon storage in their models – increasingly adopted the “solution” of combining the two.

So it was that Bioenergy Carbon Capture and Storage, or BECCS, rapidly emerged as the new saviour technology. By burning “replaceable” biomass such as wood, crops, and agricultural waste instead of coal in power stations, and then capturing the carbon dioxide from the power station chimney and storing it underground, BECCS could produce electricity at the same time as removing carbon dioxide from the atmosphere. That’s because as biomass such as trees grow, they suck in carbon dioxide from the atmosphere. By planting trees and other bioenergy crops and storing carbon dioxide released when they are burnt, more carbon could be removed from the atmosphere.

With this new solution in hand the international community regrouped from repeated failures to mount another attempt at reining in our dangerous interference with the climate. The scene was set for the crucial 2015 climate conference in Paris.

A Parisian false dawn

As its general secretary brought the 21st United Nations conference on climate change to an end, a great roar issued from the crowd. People leaped to their feet, strangers embraced, tears welled up in eyes bloodshot from lack of sleep.

The emotions on display on December 13, 2015 were not just for the cameras. After weeks of gruelling high-level negotiations in Paris a breakthrough had finally been achieved. Against all expectations, after decades of false starts and failures, the international community had finally agreed to do what it took to limit global warming to well below 2°C, preferably to 1.5°C, compared to pre-industrial levels.

But dig a little deeper and you could find another emotion lurking within delegates on December 13. Doubt. We struggle to name any climate scientist who at that time thought the Paris Agreement was feasible. We have since been told by some scientists that the Paris Agreement was “of course important for climate justice but unworkable” and “a complete shock, no one thought limiting to 1.5°C was possible”. Rather than being able to limit warming to 1.5°C, a senior academic involved in the IPCC concluded we were heading beyond 3°C by the end of this century.

Instead of confront our doubts, we scientists decided to construct ever more elaborate fantasy worlds in which we would be safe. The price to pay for our cowardice: having to keep our mouths shut about the ever growing absurdity of the required planetary-scale carbon dioxide removal.

Taking centre stage was BECCS because at the time this was the only way climate-economic models could find scenarios that would be consistent with the Paris Agreement. Rather than stabilise, global emissions of carbon dioxide had increased some 60% since 1992.

Alas, BECCS, just like all the previous solutions, was too good to be true.

Across the scenarios produced by the Intergovernmental Panel on Climate Change (IPCC) with a 66% or better chance of limiting temperature increase to 1.5°C, BECCS would need to remove 12 billion tonnes of carbon dioxide each year. BECCS at this scale would require massive planting schemes for trees and bioenergy crops.

The Earth certainly needs more trees. Humanity has cut down some three trillion since we first started farming some 13,000 years ago. But rather than allow ecosystems to recover from human impacts and forests to regrow, BECCS generally refers to dedicated industrial-scale plantations regularly harvested for bioenergy rather than carbon stored away in forest trunks, roots and soils.

Currently, the two most efficient biofuels are sugarcane for bioethanol and palm oil for biodiesel – both grown in the tropics. Endless rows of such fast growing monoculture trees or other bioenergy crops harvested at frequent intervals devastate biodiversity.

It has been estimated that BECCS would demand between 0.4 and 1.2 billion hectares of land. That’s 25% to 80% of all the land currently under cultivation. How will that be achieved at the same time as feeding 8-10 billion people around the middle of the century or without destroying native vegetation and biodiversity?

Growing billions of trees would consume vast amounts of water – in some places where people are already thirsty. Increasing forest cover in higher latitudes can have an overall warming effect because replacing grassland or fields with forests means the land surface becomes darker. This darker land absorbs more energy from the Sun and so temperatures rise. Focusing on developing vast plantations in poorer tropical nations comes with real risks of people being driven off their lands.

And it is often forgotten that trees and the land in general already soak up and store away vast amounts of carbon through what is called the natural terrestrial carbon sink. Interfering with it could both disrupt the sink and lead to double accounting.

As these impacts are becoming better understood, the sense of optimism around BECCS has diminished.

Pipe dreams

Given the dawning realisation of how difficult Paris would be in the light of ever rising emissions and limited potential of BECCS, a new buzzword emerged in policy circles: the “overshoot scenario”. Temperatures would be allowed to go beyond 1.5°C in the near term, but then be brought down with a range of carbon dioxide removal by the end of the century. This means that net zero actually means carbon negative. Within a few decades, we will need to transform our civilisation from one that currently pumps out 40 billion tons of carbon dioxide into the atmosphere each year, to one that produces a net removal of tens of billions.

Mass tree planting, for bioenergy or as an attempt at offsetting, had been the latest attempt to stall cuts in fossil fuel use. But the ever-increasing need for carbon removal was calling for more. This is why the idea of direct air capture, now being touted by some as the most promising technology out there, has taken hold. It is generally more benign to ecosystems because it requires significantly less land to operate than BECCS, including the land needed to power them using wind or solar panels.

Unfortunately, it is widely believed that direct air capture, because of its exorbitant costs and energy demand, if it ever becomes feasible to be deployed at scale, will not be able to compete with BECCS with its voracious appetite for prime agricultural land.

It should now be getting clear where the journey is heading. As the mirage of each magical technical solution disappears, another equally unworkable alternative pops up to take its place. The next is already on the horizon – and it’s even more ghastly. Once we realise net zero will not happen in time or even at all, geoengineering – the deliberate and large scale intervention in the Earth’s climate system – will probably be invoked as the solution to limit temperature increases.

One of the most researched geoengineering ideas is solar radiation management – the injection of millions of tons of sulphuric acid into the stratosphere that will reflect some of the Sun’s energy away from the Earth. It is a wild idea, but some academics and politicians are deadly serious, despite significant risks. The US National Academies of Sciences, for example, has recommended allocating up to US$200 million over the next five years to explore how geoengineering could be deployed and regulated. Funding and research in this area is sure to significantly increase.

Difficult truths

In principle there is nothing wrong or dangerous about carbon dioxide removal proposals. In fact developing ways of reducing concentrations of carbon dioxide can feel tremendously exciting. You are using science and engineering to save humanity from disaster. What you are doing is important. There is also the realisation that carbon removal will be needed to mop up some of the emissions from sectors such as aviation and cement production. So there will be some small role for a number of different carbon dioxide removal approaches.

The problems come when it is assumed that these can be deployed at vast scale. This effectively serves as a blank cheque for the continued burning of fossil fuels and the acceleration of habitat destruction.

Carbon reduction technologies and geoengineering should be seen as a sort of ejector seat that could propel humanity away from rapid and catastrophic environmental change. Just like an ejector seat in a jet aircraft, it should only be used as the very last resort. However, policymakers and businesses appear to be entirely serious about deploying highly speculative technologies as a way to land our civilisation at a sustainable destination. In fact, these are no more than fairy tales.

The only way to keep humanity safe is the immediate and sustained radical cuts to greenhouse gas emissions in a socially just way.

Academics typically see themselves as servants to society. Indeed, many are employed as civil servants. Those working at the climate science and policy interface desperately wrestle with an increasingly difficult problem. Similarly, those that champion net zero as a way of breaking through barriers holding back effective action on the climate also work with the very best of intentions.

The tragedy is that their collective efforts were never able to mount an effective challenge to a climate policy process that would only allow a narrow range of scenarios to be explored.

Most academics feel distinctly uncomfortable stepping over the invisible line that separates their day job from wider social and political concerns. There are genuine fears that being seen as advocates for or against particular issues could threaten their perceived independence. Scientists are one of the most trusted professions. Trust is very hard to build and easy to destroy.

But there is another invisible line, the one that separates maintaining academic integrity and self-censorship. As scientists, we are taught to be sceptical, to subject hypotheses to rigorous tests and interrogation. But when it comes to perhaps the greatest challenge humanity faces, we often show a dangerous lack of critical analysis.

In private, scientists express significant scepticism about the Paris Agreement, BECCS, offsetting, geoengineering and net zero. Apart from some notable exceptions, in public we quietly go about our work, apply for funding, publish papers and teach. The path to disastrous climate change is paved with feasibility studies and impact assessments.

Rather than acknowledge the seriousness of our situation, we instead continue to participate in the fantasy of net zero. What will we do when reality bites? What will we say to our friends and loved ones about our failure to speak out now?

The time has come to voice our fears and be honest with wider society. Current net zero policies will not keep warming to within 1.5°C because they were never intended to. They were and still are driven by a need to protect business as usual, not the climate. If we want to keep people safe then large and sustained cuts to carbon emissions need to happen now. That is the very simple acid test that must be applied to all climate policies. The time for wishful thinking is over.

I can’t add anything to this article because it is written by scientists and that is one thing that I know I am not!

But I can comment as a very concerned adult and really can do more that repeat what I said in yesterday’s post:

Thank goodness for our younger generation. Because these young people are coming together to fight for change. May they have universal encouragement from those of us who will never see our younger days again!

Time to end puppy mills

I am republishing a recent email that came to me.

Puppy Mills are disgraceful. Worse than that they are a scar on the face of mankind.

Yesterday I received an email that came in from the Humane Society Legislative Fund. I am sure many of you also received it.

I am going to republish it. Please help if you can.

Tell the USDA to protect puppies

Dogs suffer horribly in puppy mills. What’s worse is that over the last four years, The U.S. Department of Agriculture, which is charged with monitoring, citing and revoking licenses of these breeding facilities if they sell to pet stores, brokers or online, stopped taking their job of puppy mill enforcement seriously and the agency did not take all the necessary steps to make sure that standards of care are improved to ensure that puppy mill facilities meet the basic needs of happy and healthy dogs.

Enforcement has plummeted at USDA since 2017 and citations for violations are down more than 65%. But we have a new Administration leading the United States Department of Agriculture, one that has already promised that they are going to take animal care seriously. Now is our chance to send a message loud and clear: you must protect dogs and puppies and take puppy mill enforcement seriously, and you must ensure that standards of care are improved in puppy mills to meet the needs of the thousands of dogs living in those facilities.

TAKE ACTION
Please send a brief, polite message to the USDA using the form provided.

Want Eye Contact With Your Dog? These 4 Factors Play a Role

By Mary Jo DiLonardo

How much time does your dog spend looking into your eyes? It could depend on the shape of their head, among other factors.

Making eye contact is an important part of human relationships and it can be key in person-canine bonding too. But all dogs aren’t equal when it comes to eye gazing, finds a new study, published in the journal Scientific Reports.1

“Eye contact is an important non-verbal signal in humans. We use it in conversations to show that we are paying attention to each other,” study first author Zsófia Bognár, a Ph.D. candidate in the Department of Ethology at Eötvös Loránd University in Budapest, Hungary, tells Treehugger. “Also, the oxytocin levels in both parties rise, which plays a role in the development of social bonding.”

This social connection is easily observed when a bond is formed between a mother and a baby, she points out.

But eye contact is not so important for dog relationships. They don’t look into each other’s eyes very often, and when they do, it’s antagonistic and challenging behavior.1

“Dogs tend to make eye contact with humans, and research found that oxytocin levels also rose in both parties when owners and dogs formed eye contact,” Bognár says. “It is also known that dogs do not behave the same, differences can be found between them.” 

Earlier studies found that shorter-headed dogs were more successful at following pointing gestures from humans and watched pictures of faces for longer periods of time.21

Snub-nosed dogs have a more pronounced area in the retina of the eye responsible for central vision, so they can better respond to things happening right in front of them.1 Longer-nosed dogs have a more panoramic vision, so they’re more easily distracted by things going on all around them.1

The researchers decided to see how head shape and other factors also influenced eye contact.

Why Head Shape Matters

Researchers worked with 130 family dogs for the study. First, they measured the length and width of their heads to determine what’s called the cephalic index—the ratio of the maximum length and width of the head.

  • Short-headed or brachycephalic dog breeds include boxers, bulldogs, and pugs. 
  • Long-headed or dolichocephalic dog breeds include greyhounds, Great Danes, and German shepherds.
  • Medium-headed or mesocephalic dog breeds include Labrador retrievers, Cocker spaniels, and border collies.

Then, on to the testing.

First, the experimenter would call the dog’s name and reward the dog with a treat. Then the experimenter would stay silent and motionless, waiting for the dog to establish eye contact. They then rewarded the dog with a treat each time eye contact was made.

The experiment ended after five minutes or after 15 episodes of eye contact were made. During this test, the dog’s owner remained in the room (silent, motionless, and not looking at the dog) so the dog wouldn’t be stressed due to separation.

They measured how many times the dog made eye contact as well as how much time elapsed between eating the treat and the next time the dog made eye contact. The team found that the shorter the dog’s nose, the more quickly it made eye contact with the researcher.1

“We assumed that due to this, snub-nosed dogs could focus their attention better to their communication partner because other visual stimuli coming from the periphery could disturb them less,” Bognár says.

But there’s also the chance that pugs, bulldogs, and other similar dogs just get more of a chance to interact with people because of the baby-like way they look.1

“We couldn’t exclude the possibility that these dogs have more opportunity to learn to engage with humans and make eye contact with them,” Bognár says. “Because humans have a preference for ‘baby schema’ features, and the characteristics of snub-nosed dogs’ heads are in accordance with these features, thus the owners of these dogs may pay more attention towards them and are more likely to engage in mutual gaze with their animals.”

Age, Playfulness, and Breed Characteristics 

But the head shape wasn’t the only factor that came into play. Researchers found that a dog’s age, playfulness, and general cooperative nature due to breed characteristics all played a role in how much eye contact they made with the experimenter.1

They found dogs that were originally bred to take visual cues made more eye contact. For example, herding dogs who follow directions from the owner to work livestock, are “visually cooperative” breeds that are more likely to make eye contact. Sled dogs that run in front of a musher or dachshunds that are bred to chase prey underground are “visually non-cooperative” breeds that rely on vocal cues and don’t have to see their owners.1

Interestingly, dogs that were mixed breeds performed just as well as cooperative breeds. About 70% of the mixed breed dogs in the study were adopted from a shelter. Maybe their eagerness to make eye contact helped get them adopted in the first place, the researchers suggest.1

The researchers also found that older dogs made less eye contact. They had a harder time controlling their attention and were slower switching from the treat to the experimenter.1

A dog’s playfulness was another factor that impacted eye contact. To measure a dog’s playfulness, the off-leash dog was in a room with the owner. The experimenter walked in with a ball and a rope and offered them to the dog. If the dog chose one, they played with the toy for a minute. If the dog didn’t choose a toy, the experimenter tried to initiate a social interaction.

A dog was given a high playfulness score if it played enthusiastically with the experimenter, brought the ball back at least once, or tugged on the rope. It was given a low playfulness score if it didn’t touch the toys, ran after the ball but didn’t bring it back, or took the rope but didn’t tug on it. Researchers found that dogs with high playfulness were quicker to establish eye contact than dogs with low playfulness.1

The research uncovers a key understanding of what impacts dog-person eye contact, which can affect canine-human communication.

“Eye contact can help dogs to decide whether the message/command what the human says/shows are directed to them. They are more likely to execute a command if the human looks at them than shows its back or looks at another human/dog,” Bognár says.

“Dogs also use their gaze to communicate with humans, for example, gaze alternation can be a way to direct humans’ attention to different objects like an unreachable piece of food or a ball,” adds Bognár. “And it can also play a role in social bonding through oxytocin hormone.”

ooOOoo

Interesting! No, it is more than that. It is science at work.

Zsófia Bognár, the study’s first author, makes the point that: “Eye contact is an important non-verbal signal in humans. We use it in conversations to show that we are paying attention to each other. Also, the oxytocin levels in both parties rise, which plays a role in the development of social bonding.“

So returning to our dear Oliver we can see that the levels of oxytocin rise in Oliver and in Jean or me depending on who Oliver has engaged with.

Speaking of Oxytocin let’s go across to an article in Psychology Today that explains a little more about this important hormone.

Oxytocin is a powerful hormone that acts as a neurotransmitter in the brain. It plays an important role in reproduction, initiating contractions before birth as well as milk release. And it is thought to be involved in broader social cognition and behavior, potentially ranging from mother-infant bonding and romantic connection to group-related attitudes and prejudice. The hormone is produced in the hypothalamus and released into the bloodstream by the pituitary gland.

Why Is Oxytocin Called the “Love Hormone?”

Oxytocin has been called “the cuddle hormone” or “the love hormone” due to its association with pair bonding. It appears to help reinforce the early attachment between mothers and their infants, as well as the bonds between romantic partners. Animal research has connected oxytocin (along with another hormone, vasopressin) with the lifelong pair-bonding of prairie voles, and scientists have reported increases in oxytocin levels following orgasm in humans. There is also evidence that increases in oxytocin may encourage prosocial behavior, though not all studies have found these positive results, and some experts have undercut the idea that the hormone is a “trust molecule.”

There! Now we know!





What goes around comes around!

Another account of dogs bonding with humans.

Chernobyl is a name that anyone born before, say, 1970 will associate with a terrible nuclear accident in Russia.

As Wikipedia put it:

The Chernobyl disaster was a nuclear accident that occurred on Saturday 26 April 1986, at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union. It is considered the worst nuclear disaster in history both in terms of cost and casualties, and is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima Daiichi nuclear disaster in Japan. The initial emergency response, together with later decontamination of the environment, ultimately involved more than 500,000 personnel and cost an estimated 18 billion Soviet rubles—roughly US$68 billion in 2019, adjusted for inflation.

But recently BBC Future spoke of the bond that the guards and the abandoned dogs made.

Read it below: (Unfortunately you will have to go here to view the stunning photographs because the BBC prevents them being republished! But it is still a very interesting article.)

The guards caring for Chernobyl’s abandoned dogs

The descendants of pets abandoned by those fleeing the Chernobyl disaster are now striking up a curious relationship with humans charged with guarding the contaminated area.

It wasn’t long after he arrived in the irradiated landscape of the Chernobyl Exclusion Zone that Bogdan realised his new job came with some unexpected companions. From his first days as a checkpoint guard in Chernobyl, he has shared the place with a pack of dogs.

Bogdan (not his real name) is now in his second year of working in the zone and has got to know the dogs well. Some have names, some don’t. Some stay nearby, others remain detached – they come and go as they please. Bogdan and the other guards feed them, offer them shelter, and occasionally give them medical care. They bury them when they die.

All the dogs are, in a sense, refugees of the 1986 disaster in which Reactor No. 4 at the Chernobyl Nuclear Power Plant exploded. In the aftermath, tens of thousands of people were evacuated from the Ukrainian city of Pripyat. They were told to leave their pets behind. (Read more about the long-term toll of the Chernobyl disaster.)

Soviet soldiers shot many of the abandoned animals in an effort to prevent the spread of contamination. But, undoubtedly, some of the animals hid and survived. Thirty-five years later, hundreds of stray dogs now roam the 2,600km (1,000 sq mile) Exclusion Zone put in place to restrict human traffic in and out of the area. Nobody knows which of the dogs are directly descended from stranded pets, and which may have wandered into the zone from elsewhere. But they are all dogs of the zone now.

Their lives are perilous. They are at risk from radioactive contamination, wolf attacks, wildfires and starvation, among other threats. The dogs’ average lifespan is just five years, according to the Clean Futures Fund, a non-governmental organisation that monitors and provides care for dogs living within the Exclusion Zone.

That dogs inhabit this ruined place is well known – some of them have even become minor celebrities on social media. Clean Futures Fund co-founder Lucas Hixson, who gave up a research career to look after the animals, offers virtual tours of the Exclusion Zone featuring the dogs.

But less is known about the local workers who interact with these canines on a daily basis.

Jonathon Turnbull, a PhD candidate in geography at the University of Cambridge, realised it might be worth collecting these people’s stories.

“If I wanted to know the dogs,” he says, “I needed to go to the people who know them best – and that was the guards.”

What he discovered is a heart-warming story of the guards’ relationship with the animals they encounter in this abandoned environment – a tale that provides insights into the deep bond between humans and dogs.

The guards sometimes go to the trouble of helping the dogs by pulling out ticks embedded in their skin, or by giving them rabies injections

For instance, the guards have given several of the dogs nicknames. According to Turnbull, there’s Alpha, whose name refers to a type of radiation, and Tarzan, a dog well-known to Chernobyl tourists, who can do tricks on command and who lives near the famous Duga radar installation built by the Soviets. Then there is Sausage – a short, fat dog that likes to warm herself in the winter by lying on heating pipes. These pipes serve one of the buildings used by workers in the Exclusion Zone who are part of ongoing efforts to decommission and decontaminate the ruined power plant.

Access to the Chernobyl Exclusion Zone requires a permit, so guards are tasked with controlling checkpoints on roads in and out of the area. People who dodge these checkpoints to trespass in the Exclusion Zone are known as “stalkers”. Guards report them to the police.

When Turnbull, who lives in Ukraine’s capital Kyiv, started making regular visits to the zone, he met Bogdan, and other checkpoint guards. They were reluctant to talk at first so he had to win them over. Then he offered them to chance to take part in his research, which he says was a “turning point”. His idea was to give the guards disposable cameras and ask them to take pictures of the dogs – not posed portraits but scenes of everyday life. The guards only had one other request – “please, please – bring food for the dogs”. So Turnbull did.

The photos taken by the guards revealed how much they had developed companionships with the wandering dogs of the Exclusion Zone.

Turnbull published some of the resulting images and material from interviews with the guards in a paper in December. More recently, he interviewed one of the study participants again on behalf of BBC Future. The guard in question has asked not to be identified to avoid disciplinary action at work, so we refer to him here by the pseudonym “Bogdan”.

When Bogdan walks around the abandoned streets of the zone to check for stalkers, the dogs happily accompany him, he says. They always appear eager to see whether he, or a passing tourist, might be carrying food. Should a companion dog get distracted or run off to chase an animal, it always eventually returns to Bogdan, he adds.

The loyalty goes both ways. Turnbull says the guards sometimes go to the trouble of helping the dogs by pulling out ticks embedded in their skin, or by giving them rabies injections.

Wolves, dogs and other animals could in theory carry radioactive contamination, or genetic mutations potentially passed on by breeding, to places outside the Exclusion Zone

Monitoring who comes and goes from the Exclusion Zone sometimes makes for a dull occupation. But there are always dogs nearby.

At some checkpoints, the guards have more or less adopted some of the animals. They feed them and give them shelter. But not all are so tame. During his research, one guard told Turnbull, “We can’t inject Arka because she bites.”

Another participant spoke of one dog that was even more difficult to approach. It refuses to be touched at all. “You should just give her a pan [of food] and go. She waits until you leave and then she eats,” the guard explained.

The dogs sometimes bark at strangers on first sight, that’s their nature, says Bogdan. But so long as they don’t feel threatened, they sometimes calm down and wag their tails. Occasionally it even seems as though they’re smiling, he adds.

Generally, visitors to Chernobyl are advised not to touch the dogs, for fear that the animals may be carrying radioactive dust. It’s impossible to know where the dogs roam and some parts of the Exclusion Zone are more contaminated than others.

There is wildlife living in the Chernobyl Exclusion Zone besides dogs. In 2016, Sarah Webster, a US government wildlife biologist who was working at the University of Georgia at the time, and colleagues published a paper in which they revealed how mammals, from wolves to boars and red foxes, had colonised the Exclusion Zone. Camera trap data showed that the animals’ numbers were not noticeably lower in those areas where radioactive contamination is higher.

Animals living in the Exclusion Zone are not necessarily confined there. A later studyby Webster and colleagues, published in 2018, detailed the movements of a wolf tagged with a GPS device. It travelled 369km (229 miles) from its home range in the zone, taking a long arc to the south-east, then north-east again, eventually entering Russia.

Wolves, dogs and other animals could in theory carry radioactive contamination, or genetic mutations potentially passed on by breeding, to places outside the Exclusion Zone.

“We know it’s happening but we don’t understand the extent or the magnitude,” says Webster.

Turnbull says the guards do not generally worry about radiation, though they might occasionally use dosimeters to check a dog over.

It actually seems as though the dogs, through the companionship they offer, end up reassuring those who interact with them regularly, says Greger Larson, an archaeologist who studies animal domestication at the University of Oxford and who was not involved in Turnbull’s research.

“They’re kind of putting themselves in the shoes of the dogs,” he suggests, referring to the guards. “If the dog is fine, that means you’re fine.”

But in truth, this may only be a false sense of security.

“It’s an uncanny environment,” notes Turnbull. “You can’t see the danger. You’re constantly aware that it might be there but everything looks normal.”

Despite the fact that the dogs could pose a risk in terms of radioactivity, guards like Bogdan instead emphasise the benefits of having them around. For example, he claims to know dogs that bark in noticeably different ways depending on what they have spotted in the distance – a human stranger, a vehicle, a wild animal. Because of these helpful warning signals, Bogdan thinks of the dogs as “assistants”.

What’s happening in the Exclusion Zone is an echo of interactions with dogs that are known to have occurred within human civilisations for thousands of years, says Larson.

“We find this for the last 15,000 years or more, this is what people do, they make very close associations with not just dogs but a lot of domestic animals […] to sort of say, ‘this is our attachment to the landscape’,” he explains.

All over the world, there are dogs that inhabit a similar, in-between state – not quite fully domesticated, not quite fully wild. These are the feral dogs that roam cities and industrial areas looking for food, the ones that may become to some extent adopted by people but still wouldn’t be considered pets.

Chernobyl’s dogs also live in this sort of space, on the edge of domestication, but there is a difference argues Webster, who has participated in a separate study of Turnbull’s in the past.

“The Exclusion Zone is very different in that it’s abandoned by humans,” she says. “The only people in that landscape on a day-to-day basis, really, are the guards.” As such, the dogs’ opportunities for befriending humans are very limited.

While the outside world remains fascinated by the dogs, and their story, for many guards the connection runs much deeper. Bogdan says he is often asked why the dogs ought to be allowed to stay in the Exclusion Zone. “They give us joy,” he replies. “For me personally, this is a kind of symbol of the continuation of life in this radioactive, post-apocalyptic world.”

ooOOoo

What is so fascinating is that this interaction between the dogs and the people is an echo of the first interaction between hunter/gatherers and wolves of, perhaps, 25,000 years ago or more. And the guards of today and the dogs, whom Larson calls his assistants, are perfectly bonded.

It just goes to show that ‘what goes around comes around’!

Picture Parade Three Hundred and Eight-Four

A continuation of yesterday’s post

But first we want to remember Prince Phillip. Dear Prince Phillip. Jeannie and I watched the whole of the funeral and it was very moving.

So in terms of the photographs already shown yesterday, we had done the Hog Creek landing and the next view point and we are now up to the bridge itself.

Except that I forgot to show you another photograph of the Canyon.

The sheer walls of Hellgate Canyon

The very dramatic scene with its incredibly steep flanks was just amazing!

Now to the viewpoint just before the bridge.

We had the very good fortune to take a shot of a fisherman just upstream of us.

A rock formation on the opposite bank.

All around us were spectacular sights.

Take this shot of a bird approaching a tree standing stark on the top of a small ridge. That was just to the right of the road facing the bridge.

And the bridge itself!

It really is a very scenic place.

That is the end of my set of photographs. My eyes were truly opened.

The Rogue River and Hellgate Canyon

The art of seeing!

A few days ago there was a conversation on the photography forum Ugly Hedgehog about the camera opening one’s eyes. It struck a note in me and Jeannie and I went out in the early morning, taking the camera, to shoot photographs of the Hellgate Canyon.

It is not the first time we have been there but it is the first time I have gone with my eyes wide open!

But first some history of the Rogue River. And thanks to WikiPedia for the following.

The Rogue River in southwestern Oregon in the United States flows about 215 miles (346 km) in a generally westward direction from the Cascade Range to the Pacific Ocean. Known for its salmon runs, whitewater rafting, and rugged scenery, it was one of the original eight rivers named in the Wild and Scenic Rivers Act of 1968. Beginning near Crater Lake, which occupies the caldera left by the explosive volcanic eruption and collapse of Mount Mazama, the river flows through the geologically young High Cascades and the older Western Cascades, another volcanic province. Further west, the river passes through multiple exotic terranes of the more ancient Klamath Mountains. In the Kalmiopsis Wilderness section of the Rogue basin are some of the world’s best examples of rocks that form the Earth’s mantle. 

Hellgate Canyon is just 8 miles from where we live on Hugo Road. But just before Hellgate is the Hog Creek parking area. We stopped there and then went down to the landing stage on the edge of the Rogue River. I took some photographs.

Looking downstream.
Sign of a previous high water.
Just a close-up of a rock.
The level of the river seems pretty low.

Then we motored the short distance further on to the view point above the canyon. Took more photographs.

A faint reflection of the rocks and trees on the bank behind the river.

Then onto the viewing spot just before the bridge.

I am going to pause this now and continue it on Sunday.

No end to the insights into our dogs!

Some dogs are always jealous

The fact that some dogs get jealous from time to time is nothing new. Our own Cleo, a female GSD, is especially jealous of some of our other dogs.

Cleo as a puppy

But researchers have found dogs exhibit three human-like signatures of jealous behaviour and I want to share the details with you.

Your Dog Gets Jealous Just Imagining You With Another Canine, Study Finds

By Mary Jo DiLonardo, April 13th, 2021

To the surprise of no dog owner anywhere, a new study finds that dogs get jealous.

You may know the feeling when you’re out on a walk and stop to pet another pooch. Your dog may bark or whine, or even come in between you and the offending canine.

New research published in the journal Psychological Science finds that dogs exhibit these types of jealous behaviors even when they only imagine their owner is interacting with another dog.1 In the case of this study, the perceived rival was an artificial dog.

In the past, some scientists have insisted jealousy is strictly a human trait and people are merely projecting emotions on their pets.1

“​I think it is natural for dog owners to project a range of human thoughts and emotions onto their pets,” lead author Amalia Bastos, a Ph.D. candidate at the University of Auckland in New Zealand, tells Treehugger.

Bastos cites a study published in 2008 in the journal Cognition and Emotion where 81% of dog owners said their pets get jealous. But as much as pet owners love their animals, they are sometimes wrong about them, she says.2

That same study found that 74% of dog owners reported their pets feel guilty after misbehaving.2 But several studies have found that what people see as a “guilty look” is merely dogs responding to getting in trouble from their owners, whether they actually misbehaved or not.3,4

“Anecdotes from dog owners are interesting and can inspire fascinating research into dog intelligence and behavior, but it is important that this is taken only as a starting point for rigorous science before we can make such claims,” Bastos says.

She adds: “Work on dog jealousy to date is more promising than for guilt: our study shows that dogs exhibit three signatures of human jealous behavior. However, we caution that the fact that dogs display jealous behavior does not necessarily mean that they experience jealousy as we do.”

For the study, researchers set up an experiment where 18 dogs imagined their owners interacting with either a realistic-looking stuffed dog or a similarly sized fleece-covered cylinder that looked nothing like a dog. The fake dog played the role of a potential rival while the cylinder was a control.1

First, the dogs watched the stuffed dog next to their owner. Then, a barrier was placed between the dog and the stuffed animal so they could no longer see the potential rival. The dogs pulled strongly on their leashes when their owners appeared to be petting the fake dog behind the barrier. In a second experiment, the dogs pulled on the leashes with less force when the owners appeared to be petting the fleece cylinder.1

“We developed a novel methodology whereby we could directly measure the amount of force a dog used to pull on its lead,” Bastos explains. “This provided the first easily quantifiable, objective measure of how strongly dogs attempt to approach a jealousy-inducing interaction between their owner and a social rival.”

This is called the “approach response” as the dog tries to get closer to the owner and the potential rival. It’s also how babies and kids respond when they are jealous, Bastos says.

“The approach response is a straight-forward and clean measure which happens to be the single most universal reaction to jealousy-inducing situations in human infants and children,” she says. “Although infants and children show a range of behaviors when observing their mothers interact with another infant — including but not limited to attacking the rival, crying, seeking physical contact with the mother, throwing a tantrum, or screaming — almost all react primarily by approaching the jealousy-inducing interaction.”

Researchers were able to measure the actual strength of the approach response rather than relying on inconsistent behaviors like barking, whining, growling, or attempting to bite, which would vary among dogs.1

The Canine Subjects Showcased Jealousy Signatures 

The researchers found the dogs exhibited three human-like signatures of jealous behavior.1

These findings were different from earlier research because it’s the first to show dogs can mentally represent — or imagine — social interactions that they can’t directly see, Bastos says.

“We know this because when their owners appeared to pet a fake dog the dogs could not see behind an opaque barrier, they reacted with an approach response, which is a common jealous behaviour in humans. This suggests that dogs could mentally simulate what their owners must have been doing out of their direct line of sight,” she says.

It also showed that, like humans, dogs reacted more strongly when their owners interacted with a potential rival than with an inanimate object. And the reactions happened due to the interaction, and not when the owner and the rival were in the same room but not interacting.1

“Previous studies confounded jealous behavior with play, interest, or aggression because they never tested dogs’ reactions to the owner and the social rival being present in the same room but not interacting,” Bastos says.

“In our control condition, where owners petted a fleece cylinder, the fake dog was still present nearby,” she adds. “Dogs did not try to approach it as they did when they were being petted by the owner, showing that the interaction itself triggered their approach response, and therefore this is caused by jealous behaviour.”

Although this research is the first step, more research is necessary to figure out if dogs experience jealousy the same way people do.1

“There is still much work to be done to establish what dogs subjectively experience while exhibiting jealous behaviours, and this is a very difficult question to answer scientifically,” Bastos says. “We may never have an answer!”

ooOOoo

The researchers went to some lengths to show that the dogs were able to detect real interaction with another dog rather than a fake dog. The video is very interesting and I hope you are able to watch it.

Service dogs

The unconditional love of dogs put to a very beneficial human use!

Yesterday while we were waiting to pay for a few food items in Winco we stopped behind a woman with a small service dog. The dog was a Dachshund and had a jacket on which were sewn badges saying that this was a service dog and not to make contact.

The woman suffered from panic attacks and strongly recommended an organisation that was called ADA. In fact it is a government organisation and ADA stands for Americans with Disabilities Act.

All of which makes a nice introduction to this next item that was published on The Conversation blog site.

Service dogs can help veterans with PTSD – growing evidence shows they may reduce anxiety in practical ways

Training for service dogs starts very early.

By

March 26th, 2021

As many as 1 in 5 of the roughly 2.7 million Americans deployed to Iraq and Afghanistan since 2001 are experiencing post-traumatic stress disorder.

PTSD, a mental health problem that some people develop after experiencing or witnessing a life-threatening traumatic event, is a complex condition and can be hard to treat. Our lab is studying whether service dogs can help these military veterans, who may also have depression and anxiety – and run an elevated risk of death by suicide – in addition to having PTSD. 

We’ve been finding that once veterans with post-traumatic stress disorder get service dogs, they tend to feel less depressed and less anxious and miss work less frequently.

Complementing other forms of treatment

The traditional treatments for PTSD, such as talk therapy and medication, do work for many veterans. But these approaches do not alleviate the symptoms for all veterans, so a growing number of them are seeking additional help from PTSD service dogs.

The nation’s estimated 500,000 service dogs aid people experiencing a wide array of conditions that include visual or hearing impairments, psychological challenges, epilepsy and multiple sclerosis.

For our PTSD research, we partner with K9s For Warriors and Canine Companions for Independence, two of many nonprofits that train service dogs to work with veterans with PTSD.

There is no single breed that can help people this way. These dogs can be anything from purebred Labrador retrievers to shelter mixes.

Unlike emotional support dogs or therapy dogs, service dogs must be trained to do specific tasks – in this case, helping alleviate PTSD symptoms. In keeping with the Americans with Disabilities Act, service dogs are allowed in public places where other dogs are not.

Reducing anxiety

Service dogs can help vets with PTSD in many ways. The most common tasks include helping veterans remain calm and interrupting their anxiety. The veterans said they are asking their dogs to calm or comfort them from anxiety five times per day and that their dogs independently interrupted their anxiety three times per day on average.

For example, a dog may “cover” a veteran at a supermarket, allowing its owner to calmly turn to take something off the shelf, because veterans with PTSD can get startled if they don’t know if someone is approaching and benefit if their dogs signal that this is happening. If a veteran starts to have a panic attack, a service dog can nudge its owner to “alert” and interrupt the anxiety. At that point, the veteran can focus on petting the dog to re-center on the present – ideally preventing or minimizing the panic attack.

Aside from the tasks that their dogs are trained to do, veterans also shared that the love and companionship they get from simply being with their dogs is helping make their PTSD easier to manage.

Once veterans got service dogs, they described themselves in surveys as more satisfied with their lives, said they felt a greater sense of well-being and deemed themselves as having better relationships with friends and loved ones.

We have also measured levels of cortisol, commonly called the “stress hormone,” in veterans with service dogs. We found they had patterns closer to adults without PTSD.

Challenges and extra responsibilities

Not all veterans are willing or able to benefit from having their own service dogs.

Being accompanied by dogs in public can draw attention to the veterans. Some veterans appreciate this attention and the way it encourages them to get out of their shell, while others dread having to avoid well-meaning, dog-loving strangers. We’ve found that veterans do not expect this challenge, but often experience it.

Service dogs can also make it harder to travel, since bringing a dog along can require more planning and effort, especially because many people don’t understand the legal rights of people with service dogs and may ask inappropriate questions or create barriers that they aren’t legally allowed to do. Many experts believe educating the public about service dogs could alleviate these challenges.

What’s more, feeding, walking, grooming and otherwise taking care of a dog also entails additional responsibilities, including making sure they see a veterinarian from time to time.

There can also be a new sense of stigma that goes along with making a disability that might otherwise be hidden readily apparent. Someone who has PTSD might not stick out until they get a service dog that is always present.

Most veterans say it’s worth it because the benefits tend to outweigh the challenges, especially when appropriate expectations are set. Clinicians can play a role in helping veterans realize in advance what caring for the animal entails, to make the intervention positive for both the veterans and the dogs.

We are now completing the first registered clinical trial comparing what happens when these veterans get the usual PTSD interventions with what happens when they get that same treatment in addition to a trained service dog.

As our research proceeds, we are trying to see how the effects of a service dog last over time, how the service dogs affect veterans’ families and how we can support the partnership between veterans and their service dogs.

I am still struggling with WordPress. For example I haven’t yet worked out how to place the credit for the photograph underneath the picture. (It did it all on its own!) And there doesn’t seem to be a ‘blockquote’ command.

But coming back to the article it was a perfect description of the way that dogs are so, so good to us humans whether we have a medical need for a service dog or not.

Make Dog Treats Yourself: 3 Easy and Quick Recipes

Oh, is the dog biscuit jar empty again? Then it’s time to replenish them. But who says that you always have to buy more dog treats? You can also easily make them yourself! We’ll show you how it’s done and present you with 3 super easy dog ​​treats recipes.

Baking dog biscuits yourself: the advantages of DIY treats

Making dog treats yourself has one major advantage above all: you always know what’s in the dog biscuits. Unfortunately, many industrially produced dog treats contain dyes and preservatives. Flavor enhancers, sugar, and artificial flavors are also not uncommon. With your homemade dog treats, you know 100% what is inside – and you can take into account the individual needs, demands, preferences, and, if applicable, allergies of your four-legged friend.

Since your DIY dog treats are mostly based on a few natural ingredients, they are particularly healthy, natural, and easy to digest. In addition, making dog treats yourself is often much cheaper than buying ready-made dog treats, because the ingredients do not cost much.

What ingredients are allowed in dog biscuits?

When it comes to baking your own dog treats, there are almost no limits to your imagination. As in all other areas of dog nutrition, you should avoid prohibited, unhealthy and poisonous foods for dogs in your DIY biscuits. These include chocolate, alcohol, cocoa, grapes and sugar. Otherwise, you can use just about any food that your dog likes and benefits his health. The diverse selection of foods gives you unlimited recipe options. It is important that you can puree the food into a dough and bake it.

The most popular ingredients that keep appearing in many recipes are:

  • fish, e.g. tuna
  • beef
  • poultry
  • ground beef
  • oatmeal
  • cream cheese
  • carrots
  • bananas
  • eggs
  • spinach
  • whole wheat flour

What’s the best way to store homemade dog biscuits?

A big advantage of homemade dog treats is that they do not contain any preservatives. However, this also means that they do not last as long as industrially manufactured products. As a rule, the dog treats are plastered off relatively quickly – that’s how it should be!

Nevertheless, you can turn a few adjusting screws to ensure the longest possible durability.

In general, the drier the homemade dog biscuits are, the longer they last. Moist dog treats can unfortunately mold quickly – you should definitely avoid that! To dry out your homemade dog treats as well as possible, you can do the following:

  1. After baking, let the biscuits dry out in the oven (with the oven door open and 50–100° C).
  2. Do not pack the DIY dog biscuits in a can immediately after cooling, but leave them in the air for half a day to a full day before you store them.
  3. Pack the dog treats in classic tin cookie jars or in fabric bags so that no moisture can develop inside. Airtight plastic is unsuitable.
  4. Choose ingredients that have a long shelf life. Whole grains and oats, for example, last longer than meat and fish.

As a rule of thumb, homemade dog treats can be kept for around 3 to 4 weeks on average. The shelf life is extended by several weeks in the refrigerator as long as no moisture penetrates. They can be stored frozen for several months.

DIY dog treats: 3 simple and tasty recipes

The good thing about our delicious DIY dog biscuits is that you don’t need a lot of ingredients or fancy kitchen utensils for them. The easiest way to implement the recipes is with a food processor or a strong one. Alternatively, you can use a hand blender or even a simple whisk to prepare the dough for your DIY dog treats. In addition, cookie cutters and a rolling pin will make your work easier. If you don’t have them at hand, the cookies can also be shaped easily by hand.

Which recipe is “right” for you? Below we present our 3 favorite recipes for homemade dog biscuits. If one or the other recipe doesn’t quite suit you and your dog, we want to motivate you to try it out. There are many recipe ideas on the internet, but only you know your dog’s preferences and needs.

Therefore: Just get started, try out our recipes, and vary them from time to time. Look what supplies you still have at home and then simply test your baking skills!

Recipe # 1: Tuna treats

Preparation time (including baking time): approx. 35 min

Ingredients:

  • 1 egg
  • 1 can of tuna (in its own juice)
  • 130g oat flakes (alternatively: whole grain or potato flour)
  • Parsley or rosemary

How to make it:

Mix all ingredients together with a mixer or whisk. Add enough oat flakes or flour to make a firm but malleable dough. Now shape the biscuits as large as you want and bake them at 150°C for about 30 minutes. The baking time can vary depending on the size and thickness of the biscuits. Let your DIY tuna biscuits dry in the switched-off oven.

Store tuna dog biscuits in the refrigerator depending on the quantity.

Large portions of the fish biscuits that you will not use up within a short time should be stored in a dry, protected place in the refrigerator. This extends the shelf life of the protein-rich snacks. Depending on your needs, you can also freeze the biscuits and store them for several months.

Recipe No. 2: Cheese crunchy pearls

Preparation time (including baking time): approx. 35 min

Ingredients:

  • 100g of grated cheese
  • 100g of cottage cheese
  • 1 egg
  • 50g crumbled crispbread (or crunchy oat flakes)
  • 1 tbsp sunflower oil
  • some water if the batter is too firm

How to make it:

Mix all the ingredients together (ideally with a hand blender) and shape the dough into small balls. Place the cheese balls on a baking sheet lined with baking paper and press them into small thalers with a tablespoon. Bake the DIY dog biscuits at 180°C top and bottom heat for about 25 minutes and then let them air dry for one night.

Recipe No. 3: Liver sausage cookies

Preparation time (including baking time): approx. 40 min

Ingredients:

  • 125g liver sausage
  • 250g of oatmeal
  • 1 egg
  • 150g of cottage cheese
  • 5 tbsp sunflower oil
  • flour for rolling

How to make it:

Mix all the ingredients together to create a creamy mass. Let the dough rest in the refrigerator for about 1 hour and then roll it out on a floured work surface (about 1 cm thick). If the dough is too wet to roll out, add more oatmeal. You can read more in the article “Can dogs eat oatmeal cookies?”

Pierce or cut out your DIY dog biscuits as you wish and bake them for about 30 minutes at 150°C (180°C top and bottom heat). Allow the liver sausage biscuits to air dry overnight before stowing them in a cookie jar.

Homemade dog treats for in between or as a healthy gift idea

Baking dog treats yourself is fun, healthy, does not cost a lot, and is easier than you think! Over time, you will learn which ingredients work best for you and your four-legged friend, and you can make them happy with tasty DIY biscuits.

Since you alone determine the size, ingredients and taste of your homemade dog biscuits, you can bake delicious chews as well as small training bites that your dog can tolerate well. The DIY dog biscuits are also suitable as a great gift idea for other dog owners – ideal for Christmas, for a birthday or just for in between. Great fun for all dog lovers!

ooOOoo

I think these are great.

What would be lovely is to hear from someone who has made the treats (and I haven’t yet shown the menus to Jeannie). Even better for that person to write up a guest post for this place.
