When temperatures drop or snow starts to fall, many of us hibernate inside under warm blankets — after stocking up on bread and milk, of course. But not our dogs.
Cold? They love the cold! They run around the yard with heads held high and tails streaming, bucking like frisky foals.
What is it about the cold and snow that makes our canine friends so absolutely bonkers?
“I think it’s just fun. It’s something new. Plus snow is like a brand new toy,” says certified dog trainer and behaviorist Susie Aga of Atlanta Dog Trainer. “They have fur coats on, and they’re warm all the time so they feel good when it’s cold.”
But it’s even more amazing when it snows. That baffling, stupendous, chilling white stuff is for catching, rolling around and racing in. Like this:
Dogs have fun in the snow for probably the same reason little kids have fun in the snow: It changes their usual playground.
“It’s really no different than us humans (particularly children), who find many different forms of entertainment in the winter,” says certified professional dog trainer Katelyn Schutz in Wisconsin Pet Care.
“We toss snowballs, build snow forts, and hurdle ourselves down snowy hills on sleds, skis, and snowboards. It’s no wonder our dogs follow our lead!”
This newness isn’t just what they see, of course, but it’s what they smell and what they feel when they’re outside romping in the snow.
“More than anything, I suspect that the very sensation of snow on the body is engaging for dogs,” Alexandra Horowitz, PhD, author of “Inside of a Dog: What Dogs, See, Smell, and Know,” tells Scientific American.
“Have you ever run through the shallow waves of the sea? Why does kicking up sand and seawater make us happy? I can’t say. But it is clear that it does.”
Not all dogs love the snow and cold, Aga points out. Hairless breeds shiver and get too cold when exposed to frigid temperatures. (Above all, just pay attention; your dog will let you know if he’s not enjoying the weather.) They might need doggie sweaters or jackets before heading outside to play.
But cold-weather breeds like Siberian huskies, Newfoundlands and great Pyrenees have dense coats and were bred to withstand winter’s wallop.
“For snow dogs, that’s when they come alive,” Aga says. “They become more energetic. It allows them to run and play without getting overheated. They just feel freer in it.”
When your dog is racing and bounding around in the snow yelling, “Wheeeee!” it’s obvious he’s having fun.
“Dogs will play with something that is interesting and moves in a different way — it feels interesting,” Dr. Peter Borchelt, a certified applied animal behaviorist, told the Dodo.
“It’s about novelty and creating different movements — they’re trying to learn what is this thing and what to do with it.”
Plus, snow is really fun to catch.
That’s a really fun post and a delightful collection of videos.
It’s a truism I know but it still needs saying out loud: Dogs are amazing!
Science comes round to proving what many of us have suspected for years!
That is that dogs understand us a great deal better than was thought by the general population.
According to Statista there are a great many dog owners in the USA alone.
According to a pet owners survey, there were approximately 89.7 million dogs owned in the United States in 2017. This is an increase of over 20 million since the beginning of the survey period in 2000, when around 68 million dogs were owned in the United States.
Now not all of the owners will both adore their dogs and take an active interest in them.
When we make a road trip to visit my parents, Brodie always comes along for the ride. My mom and dad talk to my crazy border collie mix both in Italian and heavily accented English. “Sit” becomes “sitta” and they often ask him to “givva me your paw.”
Brodie looks at them intently and certainly appears to understand everything they say. It probably helps that they’re bribing him with homemade bread, but a new study finds that dogs understand human language better than we thought. Researchers found that dogs can understand when someone new is talking or when they hear a different word. The results were published in the journal Biology Letters.
For the study, researchers from the University of Sussex in the United Kingdom filmed 70 dogs of different breeds while they sat next to their owners, according to Science. They played audio recordings of men and women who the dogs had never heard speak before, and they used words that sounded very similar such as “had,” “hid” and “who’d.”
The words were chosen because they didn’t sound anything like common commands that the dogs were likely to have heard at home or during normal training.
More than a human thing
After listening to the recordings just one time, 48 of the dogs reacted either when a different speaker said the same word or when the same speaker said a different word, New Scientist reports. The other dogs didn’t respond in a noticeable way or were distracted.
Researchers looked for reactions like the dog’s ears moving forward, changing eye contact or shifting toward the speaker whenever they heard a change in a word or a speaker, as shown in the video above. They also noted how long the dogs paid attention. When they kept hearing the same word repeated over and over, their attention dropped.
“Until now, the spontaneous ability to recognize vowel sounds when spoken by different people was considered to be uniquely human,” lead researcher Holly Root-Gutteridge told the Press Association. “This research shows that, despite previous assumptions, this spontaneous ability is not uniquely human and that dogs share this linguistic talent, suggesting that speech perception may not be as special to humans as we previously thought.”
Researchers think the ability might be due to domestication, as dogs who are the most attentive to humans are the ones most likely to be used for breeding.
“I was surprised by how well some of the dogs responded to unfamiliar voices,” Root-Gutteridge told New Scientist. “It might mean that they comprehend more than we give them credit for.”
That paragraph towards the end really spells it out. It is not uniquely human to recognise vowel sounds because our dogs share this talent for speech perception.
Just another remarkable fact about our nearest and dearest of friends; our dogs!
Chilled-out canines experience a moment of utter calmness
Australian animal photographer Alex Cearns remembers the first Zen dog image she ever captured, a Shar-Pei named Suzi.
“During her photo session, I caught a shot of her with her eyes closed, and a big smile on her face. I called the image ‘Zen Dog,’ and when her owners saw it, they immediately fell in love with the vibe of the image and with Suzi’s relaxed and happy pose,” Cearns says.
“With such positive feedback, I became keen to capture the emotion and moment of being a Zen dog for other dogs who visited my studio.”
Cearns tries to take at least one Zen-like image for every dog photo session she conducts at her Houndstooth Studio, even if the process takes time. She has compiled 80 of these images of meditative canines in her new book “Zen Dogs.”
To get her canine subjects to relax, Cearns makes sure they are authentically calm and happy. Her studio is small, quiet and without many distractions.
“During my photo sessions, I realized that some types of dogs are more likely to close their eyes than others,” Cearns says. “Dogs who were fairly laid back, or who liked to lie about were easier to photograph in a Zen state, whereas dogs overly fixated on toys or treats wouldn’t close their eyes for a second, should the toy or treat disappear. They kept their eyes firmly on the prize.”
Although it might look like the dogs are zoned out or even sleeping, that’s not the case; Cearns has skillfully caught a restful moment with her camera.
“The images capture a split second blink of my dog subjects, freezing the moment in time,” she says. “Sitting only a foot away, I’m able to watch each dog subject carefully to pick up on their blinking pattern, and take a series of images just before I predict their blink.”
The book “Zen Dogs” includes photos of a wide range of breeds, interspersed with Zen-inspired quotes by Gandhi, Buddha, St. Francis of Assisi and others with thoughtful, meditative words to share. There’s this one, for example, from “Unknown”:
If you’re always racing to the next moment, what happens to the one you’re in?
“As soon as a dog visits my studio, I aim to genuinely make friends with them and ensure they are comfortable and feel secure,” says Cearns. “I try to find out what they love most — a certain type of treat, or a particular toy — and then use that knowledge to win them over.”
It’s a wonderful reminder of what is important in our lives.
Alex and Lisa have put together a remarkable video
Yesterday, in came an email from my son, Alex, about an amazing starling murmuration at the Royal Society for the Protection of Birds (RSPB).
Lisa took the video and together they uploaded it to YouTube.
Having watched the amazing video I then did a little bit of research. I came quickly across the science of murmuration and have included it below.
Murmuration refers to the phenomenon that results when hundreds, sometimes thousands, of starlings fly in swooping, intricately coordinated patterns through the sky.
Maybe you’ve seen a murmuration video before. But this one is especially beautiful. It was shot earlier this month in Wales, at Cosmeston Lakes in the Vale of Glamorgan, and posted on Facebook by the BBC Cymru Wales. (It’s not included, Ed.)
It’s all about science. Just how do the starlings manage to fly in such an amazingly coordinated way?
A few years ago, George F. Young and his colleagues investigated starlings’ “remarkable ability to maintain cohesion as a group in highly uncertain environments and with limited, noisy information” — a nice description of what goes on in a murmuration.
Going in, Young et al. already knew that starlings pay attention to a fixed number of their neighbors in the flock, regardless of flock density — seven, to be exact. Their new contribution was to figure out that “when uncertainty in sensing is present, interacting with six or seven neighbors optimizes the balance between group cohesiveness and individual effort.”
Young et al. analyzed still shots from videos of starlings in flight (flock size ranging from 440 to 2,600), then used a highly mathematical approach and systems theory to reach their conclusion. Focusing on the birds’ ability to manage uncertainty while also maintaining consensus, they discovered that birds accomplish this (with the least effort) when each bird attends to seven neighbors.
A runner who broke her leg on remote moorland was rescued after her dogs raised the alarm.
Pita Oates, 48, was left unable to stand after she fell on a three-mile run in Lancashire with her blue collies Buddy and Merlyn.
One of the dogs stayed with her as she inched down the hill, while the other ran around barking for help.
This attracted the attention of another dog walker who contacted emergency services.
Ms Oates, from Leyland, said: “They were like a tag team, Buddy never left me while Merlyn went for help.
“I would have died without a doubt, I wouldn’t have lasted the night.”
When help arrived Ms Oates, who had left her mobile phone in her camper van, was drifting in and out of consciousness and starting to suffer the effects of hypothermia.
She said: “It was the tail-end of Storm Gareth, it was freezing and I was soaking wet. The winds were horrendous.”
Ms Oates broke the femur behind her left knee and tore her anterior and cruciate ligaments on the run on Great Hill near Chorley on 12 March.
“I couldn’t stand up, I was having to bum-shuffle all the way down,” she said.
“Every time my leg touched the ground I was in pain so I rigged up a sling using the dog’s lead to keep my leg up.”
It took her 90 minutes to get down the hill by which time it had gone dark.
“Buddy never left me and Merlyn kept barking back at him – when this man came with his dog he knew something wasn’t right,” she said.
Paramedics and members of the Bowland Mountain Rescue Team, as well as two from Bolton Mountain Rescue, arrived to help rescue Ms Oates.
She spent eight days in hospital and had a titanium plate fitted but still needs another operation.
Part of me is not surprised at the behaviour of Ms Oates’ dogs. Dogs show their care and attention in so many ways. But then again I was surprised because these two dogs knew exactly what to do. One to stay and one to seek help. Which is what they did.
It was a close-run thing (pardon the pun) as Pita was starting to fade away when help arrived.
There’s a science background to being healthy and happy.
Especially as one gets older.
It’s Jean’s birthday today and we are grateful for our lot. I’m 75 now and Jean is a few years younger. But more importantly we are so grateful to have met and, subsequently, fallen in love.
As well as Jean’s love in return we have our gorgeous dogs as well (not to count in addition the two horses, the two parakeets and the cat) and they reinforce the feelings of happiness that surround us.
All of which is an introduction to an article on The Conversation that caught my eye yesterday.
I’m afraid it doesn’t mention dogs but then again we dog owners know for sure how they benefit us humans.
Are you as grateful as you deserve to be?

As a physician, I have helped to care for many patients and families whose lives have been turned upside down by serious illnesses and injuries. In the throes of such catastrophes, it can be difficult to find cause for anything but lament. Yet Thanksgiving presents us with an opportunity to develop one of the healthiest, most life-affirming and convivial of all habits – that of counting and rejoicing in our blessings.
Research shows that grateful people tend to be healthy and happy. They exhibit lower levels of stress and depression, cope better with adversity and sleep better. They tend to be happier and more satisfied with life. Even their partners tend to be more content with their relationships.
Perhaps when we are more focused on the good things we enjoy in life, we have more to live for and tend to take better care of ourselves and each other.
When researchers asked people to reflect on the past week and write about things that either irritated them or about which they felt grateful, those tasked with recalling good things were more optimistic, felt better about their lives and actually visited their physicians less.
It is no surprise that receiving thanks makes people happier, but so does expressing gratitude. An experiment that asked participants to write and deliver thank-you notes found large increases in reported levels of happiness, a benefit that lasted for an entire month.
One of the greatest minds in Western history, the Greek philosopher Aristotle, argued that we become what we habitually do. By changing our habits, we can become more thankful human beings.
If we spend our days ruminating on all that has gone poorly and how dark the prospects for the future appear, we can think ourselves into misery and resentment.
But we can also mold ourselves into the kind of people who seek out, recognize and celebrate all that we have to be grateful for.
This is not to say that anyone should become a Pollyanna, ceaselessly reciting the mantra from Voltaire’s “Candide,” “All is for the best in this, the best of all possible worlds.” There are injustices to be righted and wounds to be healed, and ignoring them would represent a lapse of moral responsibility.
But reasons to make the world a better place should never blind us to the many good things it already affords. How can we be compassionate and generous if we are fixated on deficiency? This explains why the great Roman statesman Cicero called gratitude not only the greatest of virtues but the “parent” of them all.
Gratitude is deeply embedded in many religious traditions. In Judaism, the first words of the morning prayer could be translated, “I thank you.” Another saying addresses the question, “Who is rich?” with this answer: “Those who rejoice in what they have.”
Gratitude also plays an essential role in Islam. The 55th chapter of the Quran enumerates all the things human beings have to be grateful for – the Sun, Moon, clouds, rain, air, grass, animals, plants, rivers and oceans – and then asks, “How can a sensible person be anything but thankful to God?”
In his 1994 book, “A Whole New Life,” the Duke University English professor Reynolds Price describes how his battle with a spinal cord tumor that left him partially paralyzed also taught him a great deal about what it means to really live.
After surgery, Price describes “a kind of stunned beatitude.” With time, though diminished in many ways by his tumor and its treatment, he learns to pay closer attention to the world around him and those who populate it.
Reflecting on the change in his writing, Price notes that his books differ in many ways from those he penned as a younger man. Even his handwriting, he says, “looks very little like that of the man he was at the time of his diagnosis.”
“Cranky as it is, it’s taller, more legible, and with more air and stride. And it comes down the arm of a grateful man.”
A brush with death can open our eyes. Some of us emerge with a deepened appreciation for the preciousness of each day, a clearer sense of our real priorities and a renewed commitment to celebrating life. In short, we can become more grateful, and more alive, than ever.
When it comes to practicing gratitude, one trap to avoid is locating happiness in things that make us feel better off – or simply better – than others. In my view, such thinking can foster envy and jealousy.
There are marvelous respects in which we are equally blessed – the same Sun shines down upon each of us, we all begin each day with the same 24 hours, and each of us enjoys the free use of one of the most complex and powerful resources in the universe, the human brain.
Much in our culture seems aimed to cultivate an attitude of deficiency – for example, most ads aim to make us think that to find happiness we must buy something. Yet most of the best things in life – the beauty of nature, conversation and love – are free.
There are many ways to cultivate a disposition of thankfulness. One is to make a habit of giving thanks regularly – at the beginning of the day, at meals and the like, and at day’s end.
Likewise, holidays, weeks, seasons and years can be punctuated with thanks – grateful prayer or meditation, writing thank-you notes, keeping a gratitude journal and consciously seeking out the blessings in situations as they arise.
Gratitude can become a way of life, and by developing the simple habit of counting our blessings, we can enhance the degree to which we are truly blessed.
That reference to Reynolds Price and his challenges make one think. I have been fortunate that nothing really dreadful has happened to me; apart from my father’s death when I had just turned 12. I’m getting a little hazy in terms of certain memories but that’s an old age thing rather than an illness. But to go through what he did; I just don’t know the person that I am, in terms of how I wold react to that.
But to the general tone of the article, I would hope that I can get better and better.
For it’s splendid to cultivate that disposition.
One is to make a habit of giving thanks regularly – at the beginning of the day, at meals and the like, and at day’s end.
I have been interested in eating healthy for more than 35 years. Unfortunately, my actions haven’t always matched my aims. As Mae West said, “I used to be Snow White, but I drifted.”
I drifted too, for a long time, but after writing posts for this blog for nearly 10 years, I have gotten good at it. I used the Lose It! App for a while (iPhone, iPad, Touch) a calorie counter that also breaks down nutrients and gives you a daily weight chart to demonstrate your progress. It’s not the only tool like this around, but it’s a good one. I think you are better off using a tool than not using one, especially if you are just embarking on a weight loss program.
Using that tool and practicing some self discipline I now have complete confidence in my ability to maintain a healthy body weight. I still need to work on the lean muscle mass thing, though. I love riding my bicycle and have no problem logging lots of miles and putting calories into the bank to free up my eating. I average around 100 miles a week. That covers a multitude of sins at the table. Biking is a wonderful cardio workout. Few people realize, however, it is also very stimulating for the brain. It’s a lot more fun than working with weights, but ya gotta do that, too. I write about the benefits of cardio exercise on the brain often in this blog as it is usually misunderstood and/or completely overlooked in most fitness writing. I had an aunt who died of Alzheimer’s, my mother who suffered from dementia in her final years, and my grandfather on my father’s side also had cognitive problems in his later years, so I am dead serious about protecting myself from mental decline. Check out my Page – Important facts about your brain – and exercise to read more about it.
I retired 19 years ago. I spent 20 years as a Reuters Correspondent and Editor after starting my career in men’s magazines. I taught journalism at Medill for a while and then wrote in the investment department of a major U.S. philanthropy where I spent my last few years managing $900 million in bond investments.
Now that I am retired, I have complete control over what I eat. My heart goes out to you folks who go to work every day. It is much harder to control your caloric intake. There are business lunches and dinners to attend, late days at the office, working through lunch as well as traveling. I think if I were still working I would seriously consider bringing lunch from home a day or two each week to keep a handle on my intake. With a fridge and microwave where you work, you are good to go.
When I started writing for this blog in March of 2010 I weighed 165 pounds, the lowest I had been in 15 years. I thought I had arrived at fitness and health. Now, in 2019, I weigh 155 pounds. That’s right, I have melted off a further 10 pounds from my best weight in years. My resting heart rate is under 50 beats per minute (bpm), a result of my cycling, but significantly under the ‘normal’ of 65 to 90 bpm for a guy in his upper 70’s. I have less than 16 percent body fat and a 31 inch waist (the first time since high school). I have reached this state of fitness and health following the ideas and techniques I write about in this blog. You can, too
When the blog started, I was talking the talk, over nine years later I am walking the walk. You can do the same. I am just a regular guy. If I can do it you can, too. Check out my page How to Lose Weight and Keep it Off for a start. Lots of excellent, practical principles there that I have learned and now apply to my daily life.
Just over 20 years ago my weight got out of control and I ballooned over 220 pounds. I took off 50 pounds in a year, but that only got me down to the mid-170’s. You can read How I lost 50 pounds in 52 weeks if you want chapter and verse.
I have about 40 games of backgammon going on the web. I was born January 26, 1940. I am an Aquarius and a senior citizen. At 79 years of age, I am healthier by far than I was over 20 years ago when I was in the work force and a relatively young man in my 50’s.
As a senior who presently is winning the war of the waistline, I am also grappling with the experience of aging. As part of this blog’s focus on good health I look seriously into aging and what can be done about it. I know there is no fountain of youth, but there are techniques for aging gracefully and, more importantly, retaining one’s mental powers. I promise to share with you everything I can find out about it.
The masthead photo is a shot of me taken 40 years ago by a girlfriend when we were bike riding by the lakefront in Chicago. I had a lot more hair then.
Now Tony recently published a post that I found so interesting.
It’s all about improving one’s vision.
Walking improves vision – Study.
By Tony, November 25th, 2019
As a big fan of walking I was thrilled to learn of this further benefit to the Cinderella of the exercise world. Walking leads to an increase of peripheral visual input, according to a study from the University of Wurzburg.
How do we perceive our environment? What is the influence of sensory stimuli on the peripheral nervous system and what on the brain? Science has an interest in this question for many reasons. In the long term, insights from this research could contribute to a better understanding of diseases such as ADHD and Parkinson’s disease.
Perception and the underlying neuronal activities are usually measured while subjects are sitting or lying, for example while doing magnetic resonance imaging. As a rule, the head is fixed and people are encouraged not to blink. The measurements therefore take place under well-controlled but rather unnatural conditions.
Shift of visual preference
When processing visual stimuli, however, it makes a difference whether the person is sitting or moving: When walking around, the peripheral part of the visual field shows enhanced processing compared to the central part. This can be proven both by the behaviorally measured perception of the test persons and by their brain response.
This shift in visual preference makes sense. “It is above all the peripheral visual input that provides information about the direction and speed of our movement and thus plays an important role for navigation,” says Dr. Barbara Händel. The neuroscientist from Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, and her colleague Dr. Liyu Cao have published their findings in PLOS Biology
“It was known from animals that increased body movements lead to an increased firing rate in visual areas of the brain,” says Dr. Händel. So far, there are only a few behavioural experiments available for humans that investigate the influence of movement on sensory brain areas. However, there is evidence that cognitive processes are linked to the behavioural state. “For example, some studies show that people learn better when they move,” says the JMU researcher. However, the underlying neuronal mechanisms have not yet been tested in detail.
Mobile EEG, sensors and video glasses
It is precisely such gaps in knowledge that Barbara Händel wants to close with her work. In order to explore the link between movement and perception, sophisticated technical equipment is necessary. While the test subjects walk around, they wear electrode caps and a small amplifier that records their brain waves. The EEG data are sent wirelessly to a laptop, which the subjects carry in a backpack. Motion sensors, video glasses, and a mobile device for recording eye movements complete the setting.
Quite an effort. “But we have to take this step if we want to understand human perceptual strategies during natural behavior,” says Dr. Händel. Research into perception during movement is still in its infancy. It is now up to science to ask clever questions and find out which of them can be answered with mobile technical equipment.
Many exciting research questions
Next, the JMU scientist wants to further investigate the effect of altered perception during movement. Does it only occur for visual input or possibly also in other sensory areas? Does it, in addition to navigation, perhaps also play a role in other cognitive processes such as memory and creativity?
All this is possible: experiments with rats have shown that these animals learn better, when they are in motion. And the idea that walking increases creativity has existed since ancient times. “For example, the Peripatetics, a philosophical school around Aristotle, usually were discussing while walking, from which their name derives,” says Barbara Händel.
There is also a connection between creativity and eye movements: “It is known that people blink more often the more creatively they solve a task. And we found that people also blink more often when they walk around compared to being at rest.” Obviously, there are many connections between the movements of the body, the eyes and the mental performance. Their research could reveal many more interesting aspects.
I was recently contacted by John Brooks. He writes of himself:
John Brooks loves animals from the core of his heart. Whenever he gets time, he tries to write regarding animal health & condition so that all pet lovers like you don’t fall in any hazardous situation.
He went on to explain that:
One day, Findshadow helped me to find my lost dog. So that I wrote about Findshadow.
So with no further ado, here is John’s post.
What Is Findshadow How It Can Help You Find Your Missing Dog
Dog owners share a lot of the same grievances, annoyances, and frustrations. From getting up to your pet barking in the wee hours of the night to cleaning up after your dog’s mess during walks around the neighborhood, raising and taking care of a pet comes with a host of responsibilities. And with those responsibilities come work, and with work comes grievance, annoyance, and frustration.
However, one of the worst, most gut-wrenching feelings that dog owners can relate to is the moment you realize your dog is missing. After searching every room, backtracking to the park you were at with your dog in the morning, asking your neighbors if they have seen them and posting flyers on every telephone you can find, the hopelessness begins to set in.
Luckily for you, Findshadow, a free app that helps dog owners locate their missing companions, is harnessing the power of community and technology to reunite you with your lost pets. And it is doing a pretty darn good job.
So, what is Findshadow? It is is a free smartphone app that walks owners who have lost their pets step-by-step through the process of finding their dogs.
The app offers a wide array of services and tips for their users, all for free. First, you post your lost or found dog to the community. Then, the app gives you a completely personalized, step-by-step plan on how to use the app and other resources to locate your dog. While you may think of some of these steps yourself, you’ll be surprised how thorough the process can be.
After going through these first introductory steps, you can use Findshadow to print or download personalized street flyers. Although posting your pup to the community in-app will definitely increase visibility far more than strictly putting up posters, having physical images of your dog around the neighborhood will still help you get in front of a demographic that doesn’t have Findshadow downloaded.
You can share your post on social media to easily reach friends and family. With just the three aforementioned features, Findshadow has already allowed you to reach three different populations: Findshadow users, people in your neighborhood and your connections on social media.
Getting your dog’s photo in front of as many people as possible is the recipe to success for finding your dog as quickly as possible. The more people who see it, regardless if they use Findshadow or not, the more people who will be able to identify your pet if they see it.
Findshadow also has a nifty feature that makes it easier to contact nearby shelters to ask if they have seen your dog. Even if you don’t directly contact shelters yourself, Findshadow volunteers can help snap pictures of dogs in shelters and send them to you in-app to see if they match.
The sense of community behind Findshadow is powerful. Past users of Findshadow who have successfully been reunited with their dog because of the app give back to the community by becoming active volunteers. This creates a culture where owners are helping each other out. Every dog is considered important.
The interface of the app is easy-to-use and allows users to quickly switch between different features and services. You can browse through found dog listings to double-check posts to see if someone on Findshadow has already found your dog.
The amount of positive reviews and testimonials from dog owners who gush over the app is well-justified. The app has reunited countless owners with their dogs, oftentimes within the same day they went missing.
Even if you haven’t lost your dog, it is a great app to have downloaded just in case something does come up.
This is the essence of blogging and sharing.
I hadn’t heard of Findshadow before now but will surely put the app on my phone.
Dear Dan and I recently had an email ‘conversation’ about the conversion of dog years to human years. Then, yesterday, as in Thursday, he sent me the following article from ZME Science.
Here’s a better way to calculate dog years – backed by science.
Lets’s face it, 1 for 7 years is not accurate.
November 21, 2019
By Mihai Andrei
The formula is about mid-way through the article, and it includes a simple calculator.
We learn, as kids, to approximate dog age thusly: one dog year for seven human years. That’s a decent approximation in some cases, but the more you think about it, the more it starts to fall apart.
All dog breeds tend to follow a similar pattern: they reach puberty at 10 months old. Right off the bat, it’s clear that the approximation doesn’t work here, as humans don’t really reach puberty at 6 years. Dogs can also reach 20 years or even more, and 140 years has never been recorded for a human. All in all, while it can give a ballpark estimate, the 7-for-1 approach falls short in many regards.
But now, researchers have come up with a much more accurate formula to assess dog age in human years. This one, at least, is backed by science.
It started as a way to detect factors associated with dog aging, and it focused on a relatively new concept: DNA methylation. The idea is that as we age, our DNA undergoes chemical modifications which can be used as a sort of genetic clock. It’s a way of looking at our body’s wear and tear, as the influence of diseases and unhealthy lifestyle can also be observed (to an extent) with this approach.
It’s not just humans that have epigenetic clocks. Other species have them too — including dogs. Geneticist Trey Ideker of the University of California, San Diego, and colleagues, analyzed the DNA methylation patterns in the genomes of 104 dogs (all golden retrievers), ranging from 4 weeks to 16 years of age. Although just golden retrievers were analyzed, the patterns are very similar for all breeds.
There were remarkable similarities between the DNA methylation of dogs and humans. Although the two species diverged a very long time ago, dogs live in similar environments to humans, and they even have access to similar healthcare.
Simply put, the patterns of DNA methylation in young dogs tended to be similar to those in young humans — the same goes for older dogs and older humans.
Finally, the study also demonstrates that these patterns can be used to translate the age-related physiology of one organism (in this case, dogs) to another organism (humans).
The formula is not linear, and is not exactly simple, but here it is:
The natural logarithm is used because dogs and humans don’t age similarly. Dogs seem to age very quickly in the first part of their life (which is why the age of young pups seem very weird translated into human years), but their ageing process slows down massively compared to that of humans. So the translation dog to human years cannot be linear — it is logarithmic. When your dog is 1 year old, he’s approximately 30 in human years. When he’s 2 years old, he’s 42. He’s around 60 human years by the time he’s 6, but only 70 by the time he’s 12.
It’s a weird thing to wrap your mind around and it is definitely not a perfect translation from dog years to human years, but it works much better than all existing alternatives. It also works to explain why some dogs reach sexual adolescence as early as 6 months old — the onset for that is around 10-14 years for humans. Dogs are adolescent until about 2 years, which in humans lasts until 25 years old. Then, maturity for dogs is around 2-7 years, and for humans around 25-50 years. Similar calculations (but with a slightly different formula) can be carried out for other animals, including cats and mice, researchers conclude.

M’mmm, I think I need a little more time to absorb that!
