I've heard a lot of stories about deceitful breeders, but some of this makes no sense at all to me. For instance, AKC does not care how many puppies are in a litter, except that the more puppies in a litter, the higher the registration fee. I have heard of CKCSC,USA cavalier breeders who understate the number of puppies in a litter, to avoid having to pay higher registration fees, but then those breeders will tell AKC the actual number of puppies in that same litter. With the advent of DNA testing, AKC will not condone breeders misrepresenting the name of the sire of litters. AKC perodically compares DNA of sires and littermates, and if AKC catches a breeder knowingly falsifying the litter registrations by misrepresenting the name of the actual sire, those breeders will be punished. The solution to this dilemma? One option is what I always recommend to puppy buyers: Insist upon seeing the paperwork -- the registration papers, the heart examination reports, the MRI scan reports, the eye CERF reports, and so on.
