I say DNA test! that is what I asked for from my DH this xmas for my dog! Working at an animal shelter I can tell you that papers don't mean anything. I can get papers for my dog online. Puppy store dogs are usually 90% puppymill dogs. They are very often mixed too. You should see some of the owner relinq. "pure bred" dogs from pet stores that we get in at our shelter! We laugh and laugh because they are so obviously not pure. But really, why must we have a pure bred dog? You love her to death anyway. It's really no big deal, in fact it might be better for her health in the long run if she's mixed. The pure Saints usually have some genetic health issues. BTW she looks like a SPRINGER spaniel mix to me. that would explain her smaller stature. She's cute!
