Today, vets know with a great deal of certainty if a purebred dog is at risk of developing a genetic disorder. However, determining the risk to a mixed breed is much more difficult. Most of the time, owners of mixed breed dogs don’t know with any certainty if their dog has purebred parents or grandparents.
Mixed breed Dog DNA tests have changed all that. These tests can tell owners and their vets if a mixed breed dog has a parent or grandparent that was a purebred. By knowing a dog’s purebred ancestry, a vet can then help determine if the dog is at risk of developing genetic disorders.
