Breeders, judges and historians talk about breed standards—why they work and when they don’t
Saint Bernard current and past
In the world of mammals, the domestic dog— Canis lupus familiaris, a subspecies of the gray wolf— reigns as the most morphologically diverse. Consider, for example, the extremes represented by the 155- pound South Russian Ovcharka and the seven-pound Silky Terrier. This incredible variety can be attributed in part to the dog’s basic template, which can be customized by the manipulation of a very...

The Animal Behavior Society Conference
Many presentations featured dogs
Last week, the Animal Behavior Society conference was held in Boulder, Colorado and was attended by hundreds of scientists. Besides being the 50th annual meeting, this conference was notable because of the strong representation by people who study dogs or work with them in other ways. I first attended an Animal Behavior Society conference in 1994 and I remember no talks or posters about our best...

Disagreement About Dog Domestication
Conflict among scientists who study it
Research about canine genetics and the domestication of dogs is an exciting area of study with many players, so it should surprise nobody that there is disagreement within the field. Multiple groups of researchers from around the world have compared the genomes of dogs and wolves. While they generally agree about the genetic changes that have produced differences between dogs and wolves, their...

Disadvantages of Pet Store Puppies
Unfavorable behavior compared to other puppies
In a study of over 6000 puppies, researchers found that the behavior of puppies purchased from pet stores was less desirable than the behavior of puppies obtained form noncommercial breeders. Specifically, there were 12 areas in which pet store puppies’ behavior was unfavorable compared with puppies from noncommercial breeders and two areas in which their behavior was similar. There were no...

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...
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...

Birth Control for Dogs and Cats
Innovative Approaches
This weekend I’ll be the keynote speaker at the 5th International Symposium on Non-Surgical Contraceptive Methods of Pet Population Control. The conference title is a bit of a mouthful, but the basic idea is this: Can scientists develop a drug that will permanently sterilize dogs and cats? Or, put even more simply, can we make “the pill” for pets? Now a lot of you may be asking, “Don’t we already...

Dog and Human Compulsive Disorders
Similar brain abnormalities in both species
A new study has found that Doberman pinschers with canine compulsive disorder (CCD) have abnormalities in brain structure that are much like the ones in humans who have obsessive compulsive disorder (OCD).  The study, conducted by eleven researchers, is called “Brain structural abnormalities in Doberman pinschers with canine compulsive disorder” and was published in the journal Progress in Neuro-...
