How to Verify Dog Breed Genetics

While canine DNA testing is not a perfect science yet, a number of in-home DNA tests are available to help you verify your dog's heritage. Animal shelters suspect that analyzing the DNA of dogs that come into their care might help them get adopted, since owners will have a little more background information on their pet. Breed identification can also help indicate the dog's genetic predisposition to diseases.

Instructions

    • 1

      Choose an in-home dog DNA test. Each test on the market has a different list of dog breeds they claim to be able to identify. If you think you know the heritage of dog, choose a test that includes that breed on its list. If you have no idea what breed(s) you dog is, you will be better off choosing the most comprehensive list of breeds. You could also ask your veterinarian if they have any idea what breeds your dog might be and purchase the test that includes his suggestions.

      Read the instructions included with the test and familiarize yourself with the kit. These kits include instructions, a postage-paid return envelope and cheek swabs at a minimum. Do not feed your dog within 30 minutes of the time you wish to administer the test.

      Remove the cheek swab from the end of the package and carefully swab the inside of your pet's cheek --- between the cheek and gums --- for 10 to 30 seconds. The longer you swab the cheek the higher the likelihood of an adequate DNA sample, so swab for as long as your animal will let you or until the swab is saturated. Repeat with the other swab if two are included in your kit.

      Place the wet swab(s) on a clean, dry surface for at least 30 minutes to allow it to dry. Rest the polyester tip of the swab on a clean paper towel or a freshly-opened bandage so as not to contaminate the sample.

      Place the swab(s) back inside their original packaging and fill out the included paperwork or information card. Place the paperwork and the re-packaged swabs inside the postage-paid envelope and seal it. Mail the envelope.

      Review the results of the DNA test. Each manufacturer's test processing time is different, but you can expect to wait between two and nine weeks for results. The results certificate will be categorized in order of dominant to least dominant breed or by breed percentage.
