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-...

You're Invited to a Canine Science conference
June 28 to 30—streaming live
SPARCS is a unique venture organized by Prescott Breeden and Patti Howard of The Pawsitive Packleader, Seattle Dog Training. From June 28-30, 2013, anyone in the world can see some of the leading canine science researchers in action—either in a conference hall in Redmond, WA, or streaming live to your living room. SPARCS is short for the Society for the Promotion of Applied Research in Canine...
Dog Culture: Science & History
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...

Does Reproductive Capability Matter?
Its association with lifespan and cause of death
In a new study called Reproductive Capability is Associated with Lifespan and Cause of Death in Companion Dogs, researchers report on the links of reproductive status (intact or spayed/neutered) with both lifespan and cause of death. Previous studies have suggested that sterilization increases the risk of certain cancers. However, if spaying and neutering actually does increase life span, then...

Remains of a 33,000 year-old dog found in Siberia
I had watched the dog origin wars as a chronicler of the dog-human relationship for several decades when in 2009 I was approached a young editor The Overlook Press about writing a book on the origins of the dog.  I readily agreed, and the result was How the Dog Became the Dog. Pondering the conflicting dates, places, and theories associated with the emergence of the dog, I concluded that as soon...

Dog Speak: The Sounds of Dogs
More than just noise
A friend suggested that one of the reasons we love dogs so much is that they can’t talk back. But I wonder whether that’s true. Sure, a dog won’t tell you, “You really shouldn’t have that second cookie,” but does that mean dogs are not talking back? Dogs are anything but mute, and while we usually focus on wagging tails and beguiling eyes, vocalizations—among them, barks and growls—provide us...

Behavioral Differences Between Dogs and Wolves
Dogs and wolves share a similar genetic profile. So why are their behaviors so different? The reasons aren’t clearly understood. In a recent paper in the journal Ethology , evolutionary biologist Kathryn Lord's doctoral research (University of Massachusetts, Amherst) suggests differences in later behaviors might be related to the pups' earliest sensory experiences during the critical period of...
