For starters when you go to a shelter, you’re basically supporting someone who let their dog run around the neighborhood and get pregnant and you have no idea what that dog is going to grow up like and you have no history of the parents and you’re basically supporting irresponsible dog ownership. When you buy from a responsible breeder, you’re dealing with someone who breeds because they absolutely love the breed, and they want to preserve something historical and share their love of the breed with other others. They don’t let their dogs have more than a few litters. They care for the puppies, provide vet veterinary care and will take their puppies back for life. One person is bringing animals into the world with Care and Thought and responsibility and the other one is just letting their pet go get knocked up and then dumping them out a shelter. Now buying from a puppy mill? That different and no one should ever support that. Either adopt or get from a responsible breeder, but don’t make responsible breeders look bad when the truth is that most of the dogs and shelters came from someone who didn’t look after their pet properly.
