Why would you do that? AKC is the standard club for purebred dogs in the US. If I knew my breeder did this, I wouldn't buy from her. Too easy to mislead potential buyers and I just wouldn't trust her.
Sorry, but the whole thing sounds shady to me. If I ever found out my breeder did this, (with a simple DNA test) I'd sue her since she advertised who the sire and dam were before the litter was even born.
