I am not a breeder and I am not qualified to evaluate your cute Toby for his ability to be a good stud dog. I can tell you that what these breeders are referring to I think is "LP" means Luxating Patellas or kneecaps that move out of position easily, a common fault in yorkies. I don't know why they didn't expain it after you asked but maybe they are thinking of something else. Sorry, but hope that helps and in my opinion, Toby does not have a "roach" back but he does not appear to have a level topline either. A "roach back" is one where the back is severely curved upward. If Toby is curved, it is slight, not severe from what the pictures show.

It is your decision whether to breed your male or not as you own him and there is no law against breeding a dog you own. There are a lot f breeders who breed for pet only and there is nothing wrong with that if they do it responsibly and don't breed dogs with major faults or genetic defects. We want the yorkie breed to stay the yorkie breed.

But...with that said, you said your reason for breeding was to "improve the breed" so if you are considering breeding for pet quality then you are not meeting your goal.

Good luck with whatever you decide to do.
