Have you tried to go through
www.akc.org? Thats what I did and I ended up finding a breeder who has now become a wonderful friewnd of mine. She sold me a beautiful boy and took great pride in her breed. What i did was select the breed I was interested in and than on the left hand side is Breeder contacts or something like that and that should give you good links to breeders in your area. These breeders are registered so HOPEFULLY they are not scammers if you do it this way. I personally would try to find someone in your area to purchase from. If you are unaware of Yorkie Breeders you could always ask grooming stores and vets offices- they usually know of good peoplel in your area to buy from. Good luck!
