I always suggest people look to the Yorkshire Terrier Club of America for breeder referrals. There are several in Florida you could interview. The YTCA is the mother club for the AKC, and these breeders truly are breeding for the right reasons, and that's to preserve and protect the breed. So even if you don't plan to show or breed, and just want a great pet, I suggest going to the best breeder you can find.
