DNA Testing and Purebred Dogs
Have you seen the different DNA tests out there advertising they can screen your dog for potential genetic health issues and also tell the breed in your mixed breed dog? These DNA tests can be a great tool if you understand their uses and limitations.
The American Kennel Club (AKC) has this to say about these types of tests as far as their uses in screening for genetic health issues and the limitations of the testing, "It’s the day every dog owner dreads: a bad diagnosis that drops out of the blue. These days, an increasing number of pet owners are using dog DNA tests to ward off this sudden heartbreak or help them diagnose existing symptoms. It’s a tempting idea: just take a swab from your dog’s cheek and send it to a lab, the logic goes, and a few weeks later, you’ll know which diseases your dog is genetically at risk of developing, perhaps even before anything goes wrong.
It’s so tempting, in fact, that dog DNA testing companies are proliferating, selling kits costing up to $200 that test for genes associated with more than 160 conditions. But when it comes to predicting disease in dogs, experts in dog genetics and canine health are sounding the alarm about the limitations of DNA testing at its current stage of development." ( ).
Another limitation of these tests occur when a purebred AKC registered dog is tested with a DNA test that is made to test mixed breed dogs. These testing companies themselves say that these tests are NOT designed to be used in determining whether a dog is purebred or not. Here are some quotes from the websites of the two biggest DNA testing companies- Embark and Wisdom.
From the Embark website:" These results in no way affect the “purebred” status of the dog or its standing with the registration body" ()
From the Wisdom website: " Wisdom Panel dog DNA tests aren't designed or intended to determine or validate whether a dog is purebred." (https://help.wisdompanel.com/s/article/Wisdom-Panel-test-said-my-registered-purebred-dog-isn-t-a-purebred-How-can-this-be)
In addition, the AKC does NOT recognize these tests as valid for determining whether a dog is purebred: " These new DNA tests are designed to determine the primary and secondary genetic heritage of mixed breed dogs, not to certify whether or not a dog is purebred. The AKC believes that the best way to determine parentage of a dog is still based on AKC’s long-standing DNA program and AKC does not intend to use these tests to evaluate a dog’s status as purebred. (
" There are no tests available to identify a dog’s breed purity. There are for-profit companies selling canine DNA tests that purport to identify a mixed breed dog’s heritage, i.e., Breed Identification Tests. These tests cannot tell you whether a particular dog is purebred. Rather, these tests demonstrate how closely an individual dog statistically matches the testing company’s internal reference database for the breed. " (see below email from the AKC)
So if you chose to do one of these DNA tests on your dog, please be aware of their limitations before you spend the money on this type of DNA testing.
