The kennels listed in this page are those who have at least one yorkie under their kennel prefix in this database. It is possible that a dog bred by a breeder who is included in this list is not under their name: this depend on the completeness of the information entered in the database.
Note that the presence in this list does not mean that the breeders themselves have entered the infomation: anyone who enters a pedigree in the SB Registry will have to possibly enter a breeder of ancestors or to attribute a breeder to a dog. Feel free to correct errors and omission you may find.
