Instructions
Find a canine DNA testing company online. An Internet search of "dog DNA testing" produces more than a half dozen results. Review company information to understand the scope of testing offered. In general, scientists are able to identify more than 300 DNA markers that determine specific breeds. Comparison shop based on testing information provided online.
Request and pay for a test kit from the company you choose. Test prices average $80. Wait several days for the kit to arrive in the mail. It will contain all the necessary pieces for you to obtain a DNA sample at home.
Collect a DNA sample from the inside of your dog's cheek using the special swab that comes with the test kit. This is a painless process that involves opening your dog's mouth, inserting the swab and scraping a few cells from the cheek. Package the sample and return to the company as instructed.
Wait several weeks. Testing times can vary among companies, but typically you should have your results within a month's time. You'll receive a report stating the known breeds found in your dog's DNA. In cases where breeds are difficult to determine, you will receive a list of breeds that can be eliminated by looking at your dog's DNA.
Consider the results carefully. You may be surprised if your German shepherd-looking dog carries genes for a Shar Pei or beagle. Physical appearance may have little to do with actual genetic makeup of your dog, but the test results should give you a better understanding of temperament and breed needs as you train and live with your pet.
Discuss the test results with your veterinarian, especially if the results reveal breed information that you and your vet would not have expected. Your vet will know if the genetic information means your dog is predisposed to different diseases or cannot take certain medications.
Review the results with trainers. A dog's looks might lead a trainer in one direction, but genetic testing could reveal temperament traits that require a different and more effective training approach than was expected.
