There are big Yorkies out there. They are just as lovable as the smaller ones. However, *most* breeders, whether it be the stud owner or the owner of the bitch, try to stick to the standard, which is up to 7 pounds. Your fella, as great as he may be, is twice the standard size for a Yorkie. I am afraid that you more than likely will have problems finding someone with a girl (who'd have to be bigger than he is) to who is willing to use him as a stud. IMO, if one is a "Yorkie Breeder", they are striving to produce dogs that will be, in all definitions of the term, YORKIE...weight and size included.
