I see all of the time the breeders say we have rare colors. It is done in a variety of breeds. This proves my point that not every that call themselves a breeder should be calling themselves breeders. These rare colors often mean that some other breed was introduced to the breeding stock. Examples are a white Rottweiler, white Presa, Merle pit bull. In some breeds the standards are being changed to accept the rare color or trait.
