Teacup-size puppy breeds include Pomeranian, Yorkshire, Chihuahua, Maltese and Shih Tzu. More breeds popular in teacup sizes are the Boston Terrier, French Bulldog, Papillon and Poodle. Breeders selectively breed small- or Toy-sized dogs to create even smaller dogs that they classify as Teacup size. There are no dogs that are a dedicated Teacup breed, but breeders have created Teacup versions of many Toy-size and even larger breeds.
