Dogs Attend to Color
It matters more than brightness
One of the most persistent errors about dogs is the claim that they are colorblind. It has been known for decades that dogs can see colors, but research into the details of how they use their color vision can still reveal new information. In a recent study called “Colour cues proved to be more informative for dogs than brightness”, researchers asked the simple question, “Do dogs attend to color...

Dogs are asked to "Do it"!
And imitate novel human actions and store them in memory
Researchers have shown that dogs can indeed not only mimic human actions, but can retain actions in their memory. According to a new study by Claudia Fugazza and Adám Miklósi, from Eötvös Loránd University in Hungary, this deferred imitation provides the first evidence of dogs' cognitive ability to both encode and recall actions. The research is published in Springer's journal Animal Cognition....
Dog's Life: Humane
Running the Numbers
Guest Editorial
UC Davis studies health conditions in Golden Retrievers
We humans are terrific at measuring and recordkeeping— we even know the length of Noah’s ark, in cubits (300) no less. Technology abets this trait, as computers dutifully crunch our numbers, ad, well, infinitum. As a species, however, we are not so good at appraising information to extract its meaning. Confronted with new data, we tend to overemphasize and generalize, often less than critically....

Tough Choices About End of Life
Deciding when to euthanize
Not everybody is at ease with the idea of euthanasia under any circumstances, and I understand that. Many people have moral conflicts with deciding to end the life of a pet, no matter what the reason. My perspective is that this is a highly individual decision but that I personally am comfortable with euthanizing my pets once their quality of life is so compromised or they are in such pain that...

Dogs Are Like Children To Us
Science supports what we’ve long believed
Our dogs are our kids. It’s not rocket science—we love them, they love us. They look to us for comfort and care. We call them our fur kids or our four-legged children. So, even though it’s not news to us, it’s validating to see science confirm what we already thought was true: Our dogs are like children to us. Children have been shown to explore the world most confidently if they have a strong...

Dog’s Personalitites
Studies now suggest that personality in non-human animals can be measured and evaluated, just as in humans.
All dogs are the same. really. Look at an evolutionary tree and you’ll find all domestic dogs, clustered together in one spot. But that can’t be the entire story. When asked, Rachel Licker of Lawrenceville, N.J., describes Piper, her “Basset Hound on stilts,” as incredibly goofy, communicative, playful and quick to overwhelm. According to Mary de Vachon of Nice, France, Ria, her Sheltie, is...

Why the Transformation of Wolves to Dogs Remains a Puzzle
The more I consider the continuing debate over the “time” and “place” for the transformation of wolf into dog, the more I become convinced that the puzzle remains unsolved because of human devotion to a simplistic, clever-sounding idea that never made sense in the first place. As first put forth by Raymond Coppinger, that idea was that wolves feeding on the garbage piles of quasi-permanent...

Scientists Searching for Clues to The First Dog
Village dogs’ genetic code may hold clues to canine evolution and health
Like classic twin studies that investigate the interplay of nature and nurture, comparing the genome of village dogs to modern dogs may help disentangle the long-term evolutionary effects of genetic and environmental influences. Mastiff to Min-Pin, Corgi to street cur: all dogs share the same set of roughly 20,000 genes. What makes one dog different from another—or, in the case of purebreds,...

Effects of Diet on Olfaction
Benefits of lower protein and higher fat
It’s not news to anyone that the food that we feed our dogs matters. The right food may translate to better health, proper weight management, longer life, a shinier coat, and better performance in a range of sports and activities. New research suggests that the diet of working detection dogs can even have an impact on their ability to smell. Joseph Wakshlag at Cornell and his colleagues at...

Dogs Lower the Risk of Heart Disease
The American Heart Association issued a scientific statement yesterday that yes, owning a dog may protect us from heart disease. The statement was issued by an expert panel that was convened to look at alternative approaches to combat heart disease. They were prompted to look at the benefits of pet caring because of the growing number of medical studies linking pet ownership to better health. Dr...
