I believe several recommended you visit the YTCA breeder referral. Anyone can be listed on the AKC breeders list that has AKC registered dogs. I too was not impressed with the contract or the health guarantee or honestly the looks of her dogs or puppies... There's a big lack of information about her puppies or the parents. I believe Mardelin suggested you speak with Pat (YorkieRose) who lives in Florida and could direct you to breeders she knows.
