Giving clarity on your pet's lineage
Pet DNA tests can reveal comprehensive lineages dating back to great-grandparents. Your test results will tell you if your dog's grandmother was a mixed breed or a poodle whose DNA profile matches that of fancy purebred puppies. You can check through photographs of breeds in your pet's family tree for similar characteristics. Ancestry inference based on DNA can be extremely useful.
It can be used to settle family feuds over the genealogy of a cherished mongrel, and it can at least give them hope of maintaining a pet's health. Some test providers, such as Chewy.com's Embark test, will help you connect with your dog's living relatives if they are in the company's database. Look for a test that allows you to meet your dog's siblings, cousins, and distant relatives if you think it would be amusing.
