There is not one petstore that buys from a reputable breeder, so although it is a little late now, you aren't saving anybody from adopting from one. In fact, you are making space so that puppymills can continue to breed. As long as there is demand, they will supply more puppies. If you really want to rescue a puppy or dog, adopt from a rescue. It isn't a good deed at all to buy a petstore puppy, and I am never going to give congratulations to someone that does. What is the store going to tell you, that their puppies came from a puppymill in PA? Or a BYB? If the dog you buy is not health tested for OFA, CERF, and BAER, you are only asking for trouble and steep vet bills.

This guide is a great source for finding reputable breeders. I hope that one day, pet stores only have supplies and not puppies.
