I'm sorry I offended you - it's just that so many people do not realize that 99% of all puppies sold are sold by puppymills. A good and honest breeder does not ship puppies, and actually makes little to no money on the sale of puppies. No one is trying to make you feel bad, just trying to educate you, and anyone else out there considering buying a puppy from an ad, or a petstore. Many puppymill puppies are AKC registered - but if they'll ship the dog, it's not a honest breeder.
BTW, I did buy a petstore puppy, years ago, because I didn't know about puppymills. It was AKC registered, but when I heard about puppymills, I looked at the paperwork, and the puppy came from an area of the country with a high rate of puppymills - even the vet told me I was lucky she was healthy, when she found out where I bought her (a store that only sold puppies). I think the majority of people who buy puppies from petstores or backyard breeders have no idea what goes on behind the scenes in the industry.
