I have another question? I also saw ads for Minature Australian Shepherds. I own an Australian Shepherd & was wondering how they came up with the minatures. Do they breed smaller dogs of this breed till they get them down to the minature size? Also how do they determine a new breed? Does the American Kennel Club have to accept it first? Some of the tea cup dogs that Mary Jae mentioned I don't think are accepted as a breed. They are kind of a novelty & to me look like little rodents. Just my humble opinion is all.
