In addition, an emergence of an even smaller version occurred, referred to as the Toy Australian Shepherd, with adult males weighing 12–15 pounds (5.5–7 kg) and all dogs falling under a 14-inch height at the withers. Many breeders and owners of Australian Shepherds consider the Mini and Toy to be separate breeds; others consider them to be downsized versions of the same breed. While the Mini size can be attained through selective breeding of small Australian Shepherds, the Toy size is typically a result of cross breeding with other toy breeds. ASCA and AKC consider both variants to be separate breeds.
