The Miniature American Shepherd, frequently abbreviated MAS, is a breed of herding dog with roots from the Australian Shepherd. It is a compact variety, with strong working dog behaviors.  As such, the breed is often trained for dog sports such as herding, agility, obedience, disc dog, flyball, and others.

In June 2012, the American Kennel Club (AKC) recognized the Miniature American Shepherd as a new developing breed and gave the breed Foundation Stock Service (FSS) status.

The AKC provides this service to allow breeds to continue to develop while providing them with the security of a reliable and reputable avenue to maintain their records. The MAS became fully recognized in the herding group by AKC on July 1, 2015,  and on January 1, 2015 by the United Kennel Club (UKC). The breed was developed from the North American Shepherd (formerly Miniature Australian Shepherd) program, originally intended to produce a size-variant of Australian Shepherd as a sub-breed.

Around 1993, the Miniature Australian Shepherd was determined to be too similar to the Australian Shepherd, and therefore could not participate in the AKC. The category then became known as the Miniature American Shepherd. (and still unrecognized as such by any major breed registries).

Miniature American Shepherd Club of the USA

The Miniature American Shepherd Club of the USA (MASCUSA) was selected in May of 2011 as the parent club of the Miniature American Shepherd for the American Kennel Club. The breed was formed by a split of the Australian Shepherd breed in AKC, and the incorporation of dogs previously known as Miniature Australian Shepherds and also known as North American Shepherds. MASCUSA was originally known as the Miniature Australian Shepherd Club of the USA, and then the North American Miniature Australian Shepherd Club of the USA, and was founded in 1990 as original parent club for the Miniature Australian Shepherd.
