I belong to the YTCA and we do not condone the Parti yorkie as you can not show it in conformation as it will be DQ'ed. I think all that are related to the yorkie are adorable and sometimes beautiful but I DO breed to the AKC/YTCA standard as closely as possible and not for parti's, goldens or chocolate. If you want a parti, look for one but you will not find a parti yorkie to my knowledge on the YTCA.org website as breeders. Yes, we have not so reputable breeders in YTCA but if you adhere to the code of conduct and code of ethics you will NOT find a YTCA breeder selling parti's.....
I'm not talking show dogs here either just stating not every pup in the litter will be of show quality so hence pet quality for the pet owner
