Please don't support pet stores of any kind. They all get their puppies from mills and they just don't care. Those dogs could be coming from anywhere with all sorts of problems and those prices sound ridiculous. Every time someone buys from a pet store they're perpetuating this misery. Rather invest your time in doing a lot of research and finding a good breeder who loves the breed and will give you a happy, healthy, wonderful companion. I've seen too many stories on this forum about people buying from pet stores and then dealing with the absolute heartbreak of a sick and dying puppy just a few weeks later. Just don't do it - for their sake and yours
That poor little Yorkie you mentioned - I wonder what's going to happen to her
