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-breed analysis test.
You’ve heard of the “swab test” and the “blood test” and know that both claim to unravel breed ancestry. With a little more research, you discover that the world of canine heritage tests has expanded since the first tests became available in 2007. Having a choice is great, but how do you go about comparing them and choosing the one that’s right for you?
There are several factors to consider, including the type of sample required, the number of breeds that can be identified, costs, turnaround times and the way the results are reported. Before you commit to a test that will decide the outcome of the German Shepherd/Doberman Pinscher battle, be sure you understand what you’ll be getting.
MetaMorphix Inc. (MMI) Genomics administers the Canine HeritageTM Breed Test, commonly referred to as “the swab test,” and Mars Veterinary provides “the blood test,” the Wisdom PanelTM MX Mixed Breed Analysis. These two companies have been considered the main players in this market, but new contenders are flocking to the scene. The most recent challengers are DNA Print Genomics, which offers the Doggie DNA Print, and BioPet Vet Lab, which recently unveiled the Dog DNA Breed Identification Test. Both use cheek swab samples.

The swab sample has the advantage of a collection procedure that is simple enough to be done by the owner at home. It does have some drawbacks, however, including a risk of contamination and too few cells being obtained for successful testing. To avoid the latter, BioPet Vet Lab includes a card that changes color to indicate that a sufficient sample is present. Blood samples are collected by a veterinarian and the chances of contamination and inadequate sample size are greatly reduced.
Tests also differ in the number of breeds available for comparison. Mars Veterinary interrogates the genetic signatures of more than 130 of the 159 breeds recognized by the American Kennel Club (AKC).* MMI Genomics recently announced the XL version of their test, which has a database of more than 100 breeds. The breed list available for BioPet Vet Lab contains 58 breeds. DNA Print Genomics does not report specific breed matches; rather, “15 elements of dog ancestry” are revealed, and the customer performs a search of the company’s online database to identify matches to particular breeds. Since each test interrogates a different set of breeds, sending your dog’s sample to more than one company may not return identical results.
Cost and turnaround times vary from test to test. In the past, the cost of the Wisdom Panel MX Mixed Breed Analysis test was determined solely by individual veterinary clinics, but the test can now be purchased online for $124.99, and test results are available within three to four weeks. (Your veterinarian will still have to draw the blood sample.) The swab tests are sent directly to the owners for sample collection, and prices and turnaround times vary: Doggie DNA Print, $199, six to nine weeks; Canine Heritage XL Breed Test, $119.95, four weeks (if you submitted a sample for the original version of the Canine Heritage Breed Test, you can purchase an upgrade to the XL version for $55 online); and the Dog DNA Breed Identification Test, $57.95 to $59.99, two weeks. (Prices current at press time.)
Results are presented as a certificate or report, depending on the company. MMI Genomics provides owners with a Certificate of DNA Breed Analysis. Three breed categories are included in the results: Primary, Secondary and In the Mix. BioPet Vet Lab’s Ancestry Analysis Certificate reports breeds in your dog’s genetic background in order of prevalence; a paragraph about each breed as well as a behavior, health and personality summary are included.
A report from DNA Print Genomics includes genotypes, ancestral population results and 15-N population results. Ancestral population results indicate your dog’s relationship to each of the four most basic branches of the canine family tree—wolf-like, hunters, herders and Mastiffs—while 15-N population results are a set of numbers that compare a sample to groups of breed signatures in the database. Each owner is given an ID and password that are used to query the online database for matches to specific breeds.
The Mars Veterinary report presents images of the breeds present in your dog’s ancestry, with the relative size of the image indicating the prevalence of each breed. An appearance, behavior and history section describes characteristics of each identified breed that might be seen in your dog.
As the companies run more tests and add breeds to their databases, the accuracy of the results may improve. It is also possible that even more companies will enter the canine breed ancestry DNA test field. When deciding where your dog’s sample will be submitted, determine what you want to learn and educate yourself about each of the tests. All of the companies agree that working with your veterinarian will ensure that you get the most out of your results. Who knows, choosing the test that best matches your needs could do more than just earn you a victory in the great German Shepherd/Doberman Pinscher debate!
*None of these tests are designed to identify purebred dogs, and the AKC will not accept test results for registration purposes.
