I have to send the breeder proof that he has been neutered before she'll send me his paperwork so that I can register him. I didn't have anything like that with my last Yorkie, so it was surprising at first. But then I realized it was for a good reason. She really cares about the breed and wants to know where her line continues. And if I wanted to breed, I would have no problem paying a fee for that right.
Interesting question.
