LOL, well you should have had a good idea they were going to be that way when you got them after all, otherwise the rescue group didn't do their job.
Seriously though about the papers. They don't mean squat unfortunately. They are too easy to forge and misuse. A common trick is to declare a litter larger than actually was born, or just not say that some of the litter died at birth. Now you have genuine AKC papers that can be used for whatever dog you want to use them for. In any case it just says the dog was registered, not that it's really a correct representation of the breed. The reputation of the breeder is your only protection.
