Should You Have Genetic Testing Done on Your Mixed Breed Dog?
So you’ve adopted a cute little mutt from the local animal shelter. Wonderful! You’ve not only saved a life, you’ve also robbed a puppy mill of profit by adopting rather than purchasing a dog from a pet shop.
You think your new family member might be a Golden Retriever crossed with a German Shepherd, with perhaps a little Boxer tossed in. Many people who adopt mixed breed dogs are turning to DNA test kits to try and determine the genetic heritage of their dogs.
Why Have Dog DNA Testing Done?
Certain dog breeds may be prone to specific health problems. If the owner knows the dog’s ancestry, perhaps measures can be taken to ensure the dog a longer, healthier life.

DNA Testing May Explain Some of Your Dog's Behaviors
Additionally, some behavioral traits are breed-specific. DNA testing may help explain some behaviors in your dog, such as digging, herding and barking. Knowing your dog’s genetic background may help with fashioning the best routine for training, exercise and discipline.
Finally, finding out your dog’s genetic ancestry may have other consequences, for better or worse. An example is a recent story from Salina, Kansas about a woman whose mixed breed dog was picked up by animal control officers after it got loose. The dog appeared to have a lot of pit bull in its ancestry. Since 2005, the town has banned the unregistered ownership of pit bulls and mixed breeds that are predominantly pit bulls.
DNA testing proved that the dog was not predominantly pit bull, and the owner was permitted to keep her dog. Of course, DNA testing could very well lead to the opposite outcome if it proves a dog is predominantly a banned breed.

What to Expect from Dog DNA Testing
The science of genetics is complex. The fact that your mixed breed dog appears to have characteristics of a certain breed does not necessarily mean that breed is predominant in your dog. Most of the DNA test kits do not test to determine if your dog is a purebred.
If numerous generations of your mixed breed dog’s ancestors were also mixed breed dogs (that is, if your dog has no recent pedigree ancestors), the results of the DNA test may be inconclusive. Additionally, the DNA tests available on the market test for a limited number of recognized breeds. If your dog’s ancestry is predominantly from a breed that is not included in the test, your results will be inconclusive.
Although there might be sound reasons for wanting to know your dog’s genetic heritage, in the end, you may not be able to find out with any degree of certainty. Moreover, if you have concerns about your dog’s health issues or behavior, the best place to start is by discussing those concerns with your veterinarian.
