Canine Science is Better than Common Sense

by CAPB in Companion Animal Psychology Blog

We need canine science because common sense can lead us astray.Recently I wrote about why science matters to our dogs and cats, based on findings from Dr. Paige Jarreau’s research that suggests science blogs (like this one) may contribute to readers having a better knowledge of science.I thought of this again recently because a comment I often see from readers – on any kind of science story on the internet – is "don’t we know this already? Isn’t it just common sense?"I understand the c........ Read more »

How Does a Dog's Brain Respond to the Smell of a Familiar Human?

by CAPB in Companion Animal Psychology Blog

And what does it tell us about the importance of people to their dogs?Photo: hitmanphoto / ShutterstockNew fMRI research by Gregory Berns et al (in press) shows that dog’s brains respond differently to the smell of a familiar human compared to an unfamiliar human and other canines – suggesting that certain people are special to their dogs.The research focussed on a part of the brain called the caudate, which has been much investigated in humans, monkeys and rats. The scientists explain that ........ Read more »

Will Work for Hot Dog?

by CAPB in Companion Animal Psychology Blog

Do you ever wonder how dogs are rewarded for taking part in scientific research? In some studies dogs are allowed to act naturally, but in others they need to learn something such as how to operate an apparatus they haven’t seen before, or to observe people interacting. Either way, you can’t guarantee canine cooperation. This week we thought we’d take a look at how dogs are motivated during the course of the research itself.Photo: kitty / ShutterstockNeedless to say, food is a common denom........ Read more »

Do Dogs Or Hand-Reared Wolves Pay More Attention to People?

by CAPB in Companion Animal Psychology Blog

Theories about the domestication of dogs often say they have evolved to pay more attention to humans than their wolf forebears. But the experimental evidence tends to only look at dogs. A new study by Friederike Range (University of Veterinary Medicine Vienna) and Szófia Virányi (Wolf Science Centre) compares the abilities of dogs and hand-reared wolves to utilize observations of human or dog behaviour to find food.Photo: Holly Kuchera / ShutterstockEleven wolves and fourteen do........

Can Dogs Smell Quantity of Food?

by CAPB in Companion Animal Psychology Blog

We all know dogs’ noses are amazing. From careful attention to the pee-points on their walk, to working as drug or explosive detection dogs, it’s clear dogs have an excellent sense of smell. So it’s surprising that most studies of olfaction are about specially trained dogs, and less attention has been paid to the average pet dog. A paper in press in the journal Learning and Motivation, by Alexandra Horowitz, Julie Hecht and Alexandra Dedrick, sets out to change all that by asking, can........ Read more »

Losing the Ability to Smell and Taste Didn't Miss You, Til Ya Left Me

by Christian Sinclair, MD in Pallimed: a Hospice & Palliative Medicine Blog

The Journal of Supportive Oncology (my favorite free journal with excellent practical palliative care articles) published a fantastic review of taste and odor dysfunction in cancer patients. If you read this article you could become a local expert because so few clinicians appreciate the implications or understand the treatment options for these significant quality of life markers. Obviously with this kind of endorsement it qualifies as a teaching file article.Some of you will remember when I ........ Read more »
