Dog DNA testing takes off, and generates debate

As people peer into DNA for clues to health and heritage, man's best friend is under the microscope, too.

Genetic testing for dogs has surged in recent years, fueled by companies that echo popular at-home tests for humans, offering a deep dive into a pet's genes with the swab of a canine cheek. More than a million dogs have been tested in little over a decade.

The tests' rise has stirred debate about standards, interpretation and limitations. But to many dog owners, DNA is a way to get to know their companions better.

What Vets Think of '23andMe for Dogs'

When Mars Petcare launched its first DNA test for dogs, in 2007, you could only get it through a vet. The breed-mix test required a blood draw, and Mars thought vets could help interpret the results for inquiring dog owners. But veterinarians, it turned out, weren't so keen on newfangled DNA tests then.

"We struggled with vets," says Angela Hughes, the veterinary-genetics research manager at Mars' Wisdom Health division. "There's a lot of demand out there, but sometimes the vet is a little more a hindrance than a help." So in 2009, after a technical change that allowed Mars to extract DNA from saliva instead of from blood, the company switched gears: It sold its Wisdom Panel test directly to customers.

Since then, the direct-to-dog-owner market has become bigger and more crowded: Embark, DNA My Dog, and Paw Print Genetics are just a few of the other companies eager to ship a cheek swab straight to your door.

[...] It can be tough for veterinarians to figure out what to do with these DNA results—especially when some test providers are scrupulous and others less so. "It's a little bit of a perfect storm of a slightly Wild West behavior," Aimee Llewellyn-Zaidi says. "Who are these genetic-test providers? There's no standards. There's no regulations. There's no independent assessing body." Llewellyn-Zaidi is the project director for the Harmonization of Genetic Testing for Dogs, a genetic database attempting to bring some order to the world of dog-DNA tests for health. "Veterinarians are rushing to catch up," she says. "Consumers are just going ahead and using the tests."

    It would be great to associate DNA with:

    a. chance of biting
    b. height of bite above ground (nearer to human faces)
    c. jaw strength
    d. powerful side-shaking (like pit bulls do)

    You could then prove that your pit bull actually does have the DNA to be a safe dog. Before long, they'd all be that way, because we'd get the dangerous DNA out of the gene pool.
