Breed mix tells you more than “Shih Tzu” or “Lhasa Apso.” It can tell you why your dog has to herd your whole family after dinner. Why they love chasing bunnies and hate baths. It can even tell you why they have that goofy underbite you’re obsessed with. Basically, it can help you understand your dog in a way you always wanted to, so you can be the pet parent they deserve.
