puppy mills. Plain and simple, there's no way around it. I don't care if the salesperson tells you that the dogs' health is guaranteed (c'mon, are you really going to give the sick dog back after you've had it for six months?), that he was raised with love, that he came from a reputable kennel, the truth is that if you buy a dog from a store, you are supporting puppy mills.

Yes, the puppy is cute. Yes, he's adorable. But if you buy him, you're telling the puppy mills to breed his mom again as soon as those pups have been shipped off to the store.

Never, ever, buy a puppy from a store. Especially when so many dogs are being euthanized because there's no room in the shelter…
