I got my dog from a pet store, and the lady said they get all there dogs from breeders, she gave me his papers and everything.
I'm sorry, but it does not matter one bit what the lady there said, or if you got papers. Papers mean nothing. Papers are simply a birth certificate. The names on the papers are simply what the "breeder" SAID the parents were. People can lie on their child's birth certificate, and put any father they want to down. The only way to prove it is with genetic testing. The same is true for dogs and cats.

The fact of the matter is that NO reputable breeder will EVER sell one of their puppies, kittens or birds to ANY pet store under any circumstances. NEVER. It does NOT happen. It's like dropping your new-born baby off at an orphanage, and letting the first person in the door with the right amount of cash take it home, with no background check, no application, nothing. Loving parents, be it of human babies, puppies, kitties or birds, would NOT do that, EVER.

Pet stores get their puppies, kittens and birds from ONLY one of two sources - a mill or a back-yard-breeder. Both are bad. A good, reputable breeder loves their babies, has invested thousands upon thousands of dollars in good animals, vet care, etc, and carefully screens the prospective owners of the babies. A good breeder's babies are pre-sold before they are ever born. A good breeder has a waiting list for the next litter.
