For owners of rescue dogs of mixed brood heritage, information technology can be tempting to buy a Dna kit to get intel on your pup's ancestry.

When Los Angeles resident Marie Kordus takes her rescue dog Anya out walking, some people say she looks similar a wolf or a fox. Once a little boy even said, " 'Mommy, look at that lady, she's walking a coyote!' " Kordus recalls.

But when she adopted her slender, foam-colored rescue pup, she was told she was a German shepherd mix.

Still, Kordus decided to try to find out more than about Anya's ancestry. She went online, ordered a Dna kit, swabbed Anya's mouth for saliva, put information technology in a tube, and mailed it off. One calendar week later she had results.

"What came back was that 88% of her is German language shepherd," she says. "And so that tells you lot that one parent was probably a purebred and the other parent was a mix; and they identified it as the hound family, similar a greyhound, bloodhound, or whippet."

So at present when people say "coyote," Kordus says a firm "no, not a coyote."

If you're one of the millions of Americans who owns a rescue dog, y'all may be curious about what breed your best friend is. Increasingly, pet owners are ownership DNA testing kits to attempt to figure out their dog'southward ancestry. Only the promise of these kits may exist getting ahead of the scientific discipline, according to some geneticists and animal researchers.

For dog owners, the appeal of such tests is that knowing more than well-nigh the brood could give them insights into how to handle their dog's quirks. Angela Hughes, a veterinary geneticist with Mars Petcare which makes one of the dozen or so DNA testing kits on the marketplace, says it's near understanding your dog'south behavior: "What makes them tick? Why do they look the fashion they exercise? Why exercise they act the way they do?"

It helped Hughes with her own domestic dog who turned out to be office Jack Russell terrier and part Australian cattle canis familiaris. She says it gave her an agreement that her pup needs a lot of exercise, and that "she needs certain things that terriers need like a quiet night identify to den so she tin go abroad and not feel like she has to be on patrol all the time." This, plus recognizing that "she'south going to go ballistic at the sight of any squirrel."

These kinds of insights tin can assist us humans empathise that "our dogs aren't trying to irritate u.s., it's just how they work," Hughs says.

The Wisdom Panel, the DNA test made by Mars Petcare, tests for over 350 breeds going back to the "great-grandparent level," explains Hughes. It examines the DNA from the dog'south cells for thousands of genetic markers and compares it to the company's large brood database to summate the "all-time match" in terms of breed.

The exam tin can analyze over 20 genetic traits, and Hughes cites every bit show of its accuracy that information technology can often precisely predict coat colour patterns and body traits like ear erectness, leg length and weight. In the case of Anya, the shepherd mix, Kordus says the exam results were "right on" in guessing Anya's coloring and her weight accurately, based on genetic trait analysis. "They didn't even see a picture of Anya," she says.

Though it certainly makes a fun chat-starter in the dog park, some experts warn these tests should be taken with a grain of salt. "It's hard to know how accurate they are," says Lisa Moses, a veterinarian and a researcher with Harvard Medical Schoolhouse Center for Bioethics. "Different test companies use unlike methodologies equally far as we know."

And without peer-reviewed publications describing the methods and assessing their accurateness, it's basically a "black box/trust-what-the-company says situation," says Elinor Chiliad. Karlsson, a genetics researcher with the University of Massachusetts Medical Schoolhouse and the Broad Institute of MIT and Harvard.

Hughes says Mars Petcare does non publish its testing methodology for proprietary reasons. Still, she says the company has conducted its own internal studies and finds that breed identification in mixed brood animals is 93% authentic.

From a practical point of view, bioethicist Moses worries in that location are risks to potentially inaccurate breed determination, peculiarly if the breed comes back equally a potentially problematic dog, similar a pit balderdash.

"In one case you lot have given away your dog's Dna and some visitor has the results, you may not have control over what happens to that information," she says. In that location could exist issues with prejudices and actual discrimination against sure breeds of dogs that might touch on things similar people's housing and their ability to go insurance, says Moses. "Then you may desire to retrieve twice about doing a test for that reason."

Many of the DNA tests also offer to provide information about genetic risks for potential wellness problems. This could exist helpful for dog owners considering some breeds are more susceptible to sure conditions, says Hughes. They might have an increased take chances of a bleeding disorder or of a heart condition or cancer, she says. And knowing that can impact how the veterinary cares for your pet.

Just Moses says Deoxyribonucleic acid testing for potential wellness atmospheric condition can exist highly problematic, as she argued in a recent commodity in the periodical Nature. She says the tests just aren't that accurate and the FDA doesn't regulate them. "I want pet owners and veterinarians to understand that they should not be using direct-to-consumer canis familiaris Deoxyribonucleic acid testing to make medical decisions most individual animals," she says.

There are no industry-wide standards for testing either breed or wellness condition she notes. "Manufacturers are non obligated to tell us what methodologies they use — what quality control they use," she says.

And inaccurate information on health risks could create more issues than they solve, she says. If a Deoxyribonucleic acid test suggests a vulnerability to a disease, Moses says that doesn't hateful the dog will actually get it. In fact, most dogs don't, she says.

"It'southward quite possible that you lot would cease up doing a lot of unnecessary testing to look for signs of disease if you have a dog who seemed perfectly healthy and not only could that exist costly just information technology could too be invasive and potentially fifty-fifty harmful to your dog," she says.

Making treatment decisions based on misleading Deoxyribonucleic acid results can be even more than harmful, she says: "What could possibly happen that would be actually bad is if people choose to do treatments based on a wrong diagnosis."

If you're concerned about a health problem, John Howe, a veterinary and president of the American Veterinary Medical Association says your all-time bet is to talk with your vet. "Because veterinarians are really expert at using all of our education, experiences, senses and knowledge to diagnose and care for the patients that nosotros have as well as incorporating any external data from our clients or from literature or from other veterinarians," he says.

Howe says if you lot just desire to discover out more about your canis familiaris'southward ancestry a Dna test could be a fun thing to do. Just understand, he says, that it may not exist accurate. DNA testing runs betwixt $80 and $150.
