For many dog owners, we decide after much thought to adopt a dog from a shelter or a rescue group with little to no information about their background, breed, or history. This can be the most rewarding experience as you learn the quirks of your pet. Unfortunately, this also doesn’t allow for much medical history, leading many owners to wonder: Who is my dog? What breed is she/he? What size will she/he grow to?
Through DNA testing, there is an opportunity to learn more about your dog, starting from the cellular level. Pet owners can now easily purchase a dog DNA test kit from one of several companies that specialize in canine genetic testing. These tests evaluate the gene conformation of your pet and give results of their breed composition, average age in human years, and estimated weight at full growth. They can even illuminate certain genes that can lead to illness.
