What exactly does registering mean? Papers, AKC registration...big deal. I did that with my Golden. Spent months looking for just the right situation and got a baby girl with beautiful, supposedly healthy, parents. Well, 5 years later she died from a heart defect. So stop being so high and mighty about the stupid papers. They don't mean much to me.
Bringing a new puppy into your life is a big old game of chance. No guarantees. AKC...who cares? Anybody can make up a bunch of phony-looking papers. And it would take a pretty savy consumer to recognize a fake booklet of supposed pedigree.
Designer puppies aren't the worst thing in the world. If someone wants to mix a poodle father and bichon mother...what's the difference? Many people don't care about the integrity of breeding dogs...they just want a cute dog that doesn't shed.
