The Dog Project: Researching Canine Behavioral Genetics
An investigation into the genetics of canine anxiety, phobias and fears
“This is the job that Solo got me,” says Melanie Lee Chang, PhD, a biologist who got her doctorate in evolutionary biology and physical anthropology at the University of Pennsylvania and is currently working in canine molecular genetics. Solo is her eight-year-old Border Collie. The job is as a postdoctoral scholar in the Department of Psychiatry at the University of California, San Francisco (...

Decoding the Dog Genome
A female Boxer provides the DNA for the first complete sequence of the dog genome—what will it mean to the health of man and dog?
“The dog is everywhere what society makes him,” wrote Charles Dudley Warner in the January 1896 issue of Harper’s New Monthly Magazine. Elaine Ostrander and Heidi Parker update that message in the November 2005 issue of the online journal, Public Library of Science—Genetics: “The domestication of the dog from its wolf ancestors is perhaps the most complex genetic experiment in history, and...

Deconstructing the Gene Pool
Dr. Mark Neff and his team uncover the surprising origin of a potentially deadly mutation
Until the mid-19th century, any hodge-podge of similar-looking dogs performing similar tasks was awarded the right to be called a breed. However, as inventions (such as guns) mechanized jobs that dogs normally performed, many breeds—like the tumbler, who “tumbled and turned” to mesmerize prey—simply sank back into the ancestral soup, taking their unique traits with them. One of these ancient...

Fala, the Presidential Dog
How a special little dog made America’s house his home
Arguably the most important dog in World War II never saw combat; in fact, he was one of the breeds deemed unfit for duty by virtue of his stubby legs and long coat. But he was also of a breed that had been considered suitable for a gentleman to keep in town since the mid-19th century, and in President Roosevelt he met the perfect human companion. Roosevelt’s cousin, Margaret “Daisy” Suckley,...

DNA Testing
Which DNA test should you choose to settle the “what’s in the mix” question?
For years, you’ve argued with your spouse that the 60-pound, black-and-tan tennis ball–chaser who takes you for walks and sweeps the coffee table clean with his tail is a German Shepherd mix, and that there is absolutely no Doberman Pinscher in there. Finally, in order to end the breed debate once and for all and restore peace to your household, you’ve decided to settle the question with a mixed-...

The Future of Dogs
Breeding for looks, not function, threatens dogs’ well-being
Like many people, my wife Diana and I had long been in the habit of buying purebred dogs without bothering to learn much about their breeding beforehand. And so it was in 1977, when we made an impulse purchase of a Jack Russell Terrier named Phineas. Despite the many other wonderful dogs who’d blessed our lives, we’d never known another like Phineas. Though short-legged and weighing barely 15...

Dogs: Wolf, Myth, Hero & Friend
Sniffing out the facts and exploring the relationship between our two species
No observer can help but remark upon the incredible variety of sizes, shapes, temperaments and behaviors of the dog—from the one-pound Chihuahua to the 200-pound Mastiff; the stubby-legged, placid Basset Hound to the long-legged, fleet Greyhound. Nowhere else in the animal kingdom does so much morphological diversity exist within a single species. In large measure, the 400 or so breeds of dog...

The Wolf Who Stayed
A domestication that went both ways
That the dog is descended from the wolf—or more precisely, the wolf who stayed—is by now an accepted fact of evolution and history. But that fact is about all that is agreed to among the people who attempt to answer fundamental questions about the origins of the dog—specifically, the who, where, when, how and why of domestication. Dates range from the dog’s earliest appearance in the...

The Wolf in Your Dog
Evolutionary pathways
"Though in their deep heart’s core, there is a commonality of origin, spirit, emotional intelligence and empathetic sensibility, the wild wolf looks through us, while the dog looks to us. " Of all the myriad members of the animal kingdom, the domesticated dog (Canis lupus familiaris) is closest to us. With individual exceptions in other species, this canine species is the most understanding, if...

Can DNA Decipher the Mix?
Unraveling the genetic tapestry provides clues to breeds and their mixes
A mongrel dog is like a box of chocolates: You never know what you’re going to get. And therein lies the appeal. What’s more fun than serendipitous unpredictability all bundled up in puppy fur? But when that puppy grows up, we inevitably make assumptions about her ancestry based on how she looks and behaves. Our logic goes like this: “If my pooch is long and low to the ground, and she never barks...
