Admiration for lost souls!

Back to dogs!

The last two weeks predominantly have been posts under the umbrella of WordPress’ Writing 101 event. I’m bowing out at the half-way point.

Simply because the arrival of Pedy and the huge pleasure that Jean and I have had from rescuing him meant I wanted to return to writing most of the time about dogs and what we humans can learn from them.

So with that in mind it has been widely reported in recent days about the news that we humans bond with dogs as we do with babies. Let me quote a little from a recent article from the BBC.

Gazing into a dog’s eyes can stimulate the same bonding process that occurs between mother and child.

Presented by Zoe Gough

Eye contact between a mother and her baby strengthens their attachment by activating the so-called ‘love hormone’ – oxytocin – in the mother’s brain.

This drives emotional bonding between parent and offspring by encouraging both nurturing and interactive behaviours.

Studies have shown that stroking or making eye contact with a dog can trigger a similar release of oxytocin in a human’s brain.

Now a team of Japanese scientists have found that the “mutual gaze” between dogs and their owners can lead to a bond that is similar to that between a mother and child, with humans experiencing the same feelings of affection for their dogs as they might do for their family, therefore helping to bring the species closer.

The findings are reported in the journal Science and also note that wolves do not show the same response. Authors suggest this means that the bonding process probably co-evolved in both species as dogs became domesticated.

It can be said that dogs successfully cohabit with humans because they have been successful in adapting the bonding mechanism to relations with humans,” said lead author Dr Miho Nagasawa, from the School of Veterinary Medicine, Azabu University, Japan.

All of which serves as a wonderful foreword to how the stray dogs manage so successfully to exist on the Moscow subway. I reported on this back in 2011 under the title of The Tenacity of Dogs but immediate neighbours Larry and Janell sent me a link to a much more detailed account of these subway dogs. Here is the remarkable story.

The Life of Subway Dogs

To those of you who own dogs or like them, this should be interesting.

The elite of Moscow’s 35,000 stray dogs are about 500 Russian dogs constantly living in the Moscow subway (Metro). About 50 of subway dogs have learned to ride the trains, commuting from quiet suburbs stations where they spend the night to downtown where it’s easier to get some food.

Each morning, like clockwork, they board the subway, off to begin their daily routine amidst the hustle and bustle of the city. But these aren’t just any daily commuters. These are stray dogs who live in the outskirts of Moscow Russia and commute on the underground trains to and from the city centre in search of food scraps.

Then after a hard day scavenging and begging on the streets, they hop back on the train and return to the suburbs where they spend the night.

SW3

Living in the subway is just a survival tactic the Moscow stray dogs have come up with. The subway dogs have figured out how to use the city’s huge and complicated subway system, getting on and off at the stops they need. They recognize the desired station by smell, by recorded announcer’s voice, and by time intervals basing on their biological clocks. Usually they ride first or last car to keep away from crushes.

SW4

Experts studying the dogs, who usually choose the quietest carriages at the front and back of the train, say they even work together to make sure they get off at the right stop – after learning to judge the length of time they need to spend on the train.

SW5

In Soviet times stray dogs were barred from subway. Moscow Metro’s passengers are so accustomed to dogs on subway – sleeping on empty seats and hanging around stations – that they do not pay any attention.

SW6

For these strays the Moscow Metro is their home. The subway dogs get outside to do all their deeds and behave friendly to the passengers. They have very good instincts about people, greeting happily kind passengers and avoiding contacts with intolerant persons. And they always find somebody who will share food with them.

SW7

With children the dogs “play cute” by putting their heads on youngsters’ knees and staring pleadingly into their eyes to win sympathy – and scraps.

SW8

Dogs are opportunistic and intelligent, and when they figured out they were no longer chased away from the subway stations, they began hopping trains for a lift into the city. The Moscow subway system is a maze that can be confusing for people, but the dogs appear to have learned the system.

SW9

Once in the city, the dogs have their own special ways of getting food. Some position themselves outside butcher shops and wait for dog lovers coming out of the shop to toss them a bone. Others have refined a technique of sneaking up behind people who are eating food and surprising them with a loud bark which hopefully scares the person into dropping whatever they’re eating. If the dog is successful in getting the person to drop their food, he grabs his prize and runs.

SW10

Packs of stray dogs are led not by the strongest or most dominant member, but by the most intelligent dog in the pack. The dogs understand living among people in a large city requires brains and not muscle to survive. Researchers have observed dog packs selecting pack members that are smaller and cuter than the other ones who are then sent out to beg for food.

SW11

The dogs also don’t leave messes laying around where someone can step in them, and they relieve themselves in out of the way spots away from the main traffic areas. The subway riding stray dogs of Moscow have essentially learned how to interact with people and move among them in order to survive.

Aren’t dogs the most remarkable species of animal!

The Secret Life of Dogs.

Dogs watch us all the time and read our body language like a sixth sense.

Dogs watch us all the time and read our body language like a sixth sense. They also smell our bodies for changes.

Max smelt cancer in Maureen before any medical scans could pick it up. Dogs do this naturally and can be trained to pick up on tiny volatile chemicals given off by cancerous tumors. They can even be taught to alert diabetics to low blood sugar levels.

This dog can smell cancer

This is Frankie, a German shepherd mix. He can sniff out thyroid cancer in patients’ urine samples with 88% accuracy, according to a new study.

A trained scent dog accurately identified whether patients’ urine samples had thyroid cancer or were benign (noncancerous) 88 percent of the time, according to a new study by researchers at University of Arkansas for Medical Sciences (UAMS). The results were presented March 6 at the Endocrine Society’s annual meeting in San Diego.

Approximately 62,450 new cases of thyroid cancer will be diagnosed in the US this year, and around 1,950 Americans will die from the disease.

Techniques used to diagnose thyroid cancer include fine-needle aspiration biopsy, which involves the patient having a thin needle inserted into the thyroid gland in the neck to obtain a tissue sample. Donald Bodenner, MD, PhD chief of endocrine oncology at UAMS is the study’s senior investigator. Bodenner said:

Scent-trained canines could be used by physicians to detect the presence of thyroid cancer at an early stage and to avoid surgery when unwarranted.

Study-coauthor Arny Ferrando previously “imprinted,” or scent-trained, a rescued male German Shepherd-mix named Frankie to recognize the smell of cancer in thyroid tissue. Ferrando, who noted that dogs have at least 10 times more smell receptors than humans, said:

Frankie is the first dog trained to differentiate benign thyroid disease from thyroid cancer by smelling a person’s urine.

In this study, 34 patients gave a urine sample before they went on to have a biopsy of suspicious thyroid nodules and surgery. The surgical pathology result was diagnosed as cancer in 15 patients and benign thyroid disease in 19. These urine samples were presented one at a time to Frankie to sniff. Frankie had been trained to alert to a cancer sample by lying down, and turning away from a benign sample to alert the absence of cancer.

The dog’s alert matched the surgical pathology diagnosis in 30 of the 34 study samples, the investigators reported.

Bottom line: A new study by University of Arkansas for Medical Sciences (UAMS) researchers presented March 6, 2015 at the Endocrine Society’s annual meeting in San Diego described Frankie, a trained scent dog that accurately identified whether patients’ urine samples had thyroid cancer or were benign 88 percent of the time.
