Doggy quote of the month for October

“Dogs are my favorite role models. I want to work like a dog, doing what I was born to do with joy and purpose. I want to play like a dog, with total, jolly abandon. I want to love like a dog, with unabashed devotion and complete lack of concern about what people do for a living, how much money they have, or how much they weigh. The fact that we still live with dogs, even when we don’t have to herd or hunt our dinner, gives me hope for humans and canines alike.”

– Oprah Winfrey, actress, writer, talk show host, philanthropist

Gambling wolves take more risks than dogs

Would you rather get 100 euros for certain, or have a fifty-fifty chance of receiving either 200 euros or nothing? Most choose the first, as humans tend to be “risk-averse”, preferring a guaranteed pay-off over the possibility of a greater reward. It is thought that the human preference for “playing it safe” has evolved through natural selection: when you live precariously, like our remote ancestors, losing all your food reserves might be catastrophic, while adding to them might not make much difference to your chances of survival.

Here, in one of the first studies on risk preferences in animals other than primates, scientists show that wolves are consistently more prone to take risks when gambling for food than dogs. When faced with the choice between an insipid food pellet and a fifty-fifty chance of either tasty meat or an inedible stone, wolves nearly always choose the risky option, whereas dogs are more cautious.

“We compared the propensity to take risks in a foraging context between wolves and dogs that had been raised under the same conditions,” says Sarah Marshall-Pescini, a postdoctoral fellow at the Messerli Research Institute at the Veterinary University of Vienna and the Wolf Science Centre, Ernstbrunn, Austria, the study’s first author. “We found that wolves prefer the risky option significantly more often than dogs. This difference, which seems to be innate, is consistent with the hypothesis that risk preference evolves as a function of ecology.”

The study was done at the Wolf Science Centre, Ernstbrunn, Austria, a research institute where scientists study cognitive and behavioral differences and similarities between wolves and dogs. Here, wolves and dogs live in packs, under near-natural conditions within large enclosures.

Marshall-Pescini let each of 7 wolves and 7 dogs choose 80 times between two upside-down bowls, placed side-by-side on a movable table-top. The animals had been trained to indicate the bowl of their choice with their paw or muzzle, after which they would receive the item that was hidden beneath it.

The researchers had taught the wolves and dogs that beneath the first bowl, the “safe” option, was invariably an insipid food pellet, while beneath the second bowl, the “risky” option, was either an inedible item, a stone, in a random 50% of trials, and high-quality food, such as meat, sausage, or chicken, in the other 50%. As a control, the side for the “safe” and “risky” option changed between trials, but the animals were always shown which side corresponded to which option; whether they would get a stone or high-quality food if they chose the “risky” option was the only unknown. Rigorously designed control trials confirmed that the animals understood this rule, including the element of chance.

Wolves are much more prone to take risks than dogs, show the results. Wolves chose the risky option in 80% of trials, whereas dogs only did so in 58% of trials.

The researchers believe that dogs evolved a more cautious temperament after they underwent an evolutionary shift from their ancestral hunter lifestyle to their present scavenger lifestyle, which happened between 18,000 to 32,000 years ago when humans first domesticated dogs from wolves. Previous research has suggested that species that rely on patchily distributed, uncertain food sources are generally more risk-prone. For example, chimpanzees, which feed on fruit trees and hunt for monkeys, are more risk-prone than bonobos, which rely more on terrestrial vegetation, a temporally and spatially reliable food source.

“Wild wolves hunt large ungulates — a risky strategy, not only because hunts often fail, but also because these prey animals can be dangerous — whereas free-ranging dogs, which make up 80% of the world’s dog population, feed mostly by scavenging on human refuse, a ubiquitous, unlimited resource. So dogs no longer need to take risks when searching for food, and this may have selected for a preference to play if safe,” concludes Marshall-Pescini.

The Olympic diving dogs of Farmers Insurance

The Olympics are in full swing, covered in all forms of media but especially television.  I have to say that the Olympic-themed commercials in New Zealand are pretty bland.

My hat goes off to Farmers Insurance for their Flooded House Diving Dogs Competition commercial series – a great use of dogs and the Olympic theme.  A group of unattended dogs accidentally flood their home and compete in their own diving competiton.

There are eight commercials in the series starting with the Intro.  Once the Intro plays, simply click on the next video.

Enjoy watching Tank, Bubbles, Nacho, Churchill, Toby, Oksana and Montana…

Cancer sniffing dogs

I write frequently about special dogs and assistance dogs. But this post isn’t about research – it’s about real-life stories where common pet dogs have detected cancer in their owner.

For example, I have a client in my massage practice who said that her dog was acting differently towards her.  We initially attributed this to stress in the home – since they had recently moved house with all of the associated angst. And then came a diagnosis of bladder cancer and she’s now in the middle of aggressive treatment for it.. On reflection, I believe her dog, who is a sensitive boy, picked up on the scent of her cancer but he didn’t know how to tell her.

And then this week, I read about Banjo who lives in North Carolina with his owner, Tim Buckner.  Banjo acted strangely to a wart on his Tim’s arm…and when Tim went to get it checked by a dermatologist, he was diagnosed with melanoma.

We know that dogs have extremely sensitive noses.  And I include here the PBS NewsHour item about dogs and how they can detect cancer.  This piece opens with yet another dog owner telling the tale of how her dog detected her cancer.

Dogs continue to show us unique ways they can help us and our quality of life.  You may have saved your pet, but your pet could also save you.
