For those of you who ask, "How small is a papillon when they are born?" I thought I might post a photo of a brand new baby girl. She weighed at birth 4 ounces and the stick of butter weighs 4.2 ounces. Just because she was this small at birth she grew up to be a normal size girl. Beware of breeders who guarantee you that a small puppy will stay small unless they are at least 6 months old, and even then they can continue growing ending up at 9 or 10 inches. Beware anyone trying to sell you a "teacup" papillon.
