The best way to predict what the pups will look like when full grown, is to see both parents. While the YTCA forbids the terms "baby doll face" or "teddy bear" a standard Yorkie should neither have a long snout or too short of one, but one described as medium. I would not buy from a breeder advertising such things as baby doll or teddy bear face because it means they don't follow the rules set for by the Yorkshire Terrier Club of American. If they don't follow these rules than they probably don't follow other rules such as health screening.
