The major problem that I have with breeding is that breeders are adding to the overpopulation problem. If someone wants a pure breed they can simply find a rescue society for that breed of dog. For instance there are Pug Rescue societies......if someone wanted a Pug they can call these people and get hooked up. This whole dogs and cats as "pets" thing never should have happened to begin with. I have dogs and cats myself...its better than having them be homeless or killed by a shelter...or in an abusive home. But people should be doing everything in their power to control this overpopulation problem, and breeding is hurting it more than anything.
