Miniature Australian Shepherd

Dog breed

Overview

The Miniature American Shepherd, frequently abbreviated MAS, is a small herding dog breed. The MAS is highly intelligent and biddable. The breed is often trained for dog sports such as herding, agility, obedience, canine freestyle, flyball, and others. The Miniature American Shepherd was recognised by the American Kennel Club (AKC) in 2015 and is the club's 186th breed. In September 2019, the Fédération Cynologique Internationale (FCI) officially accepted the breed.

History

History: The MAS was bred first in the United States as a small herding and working dog. The Miniature American Shepherd (at that time still known as the Miniature Australian Shepherd) was first developed in the late 1960s by breeding what was thought to be small size Australian Shepherds, and by the mid-1970s the breed had reached its current desired size. In many areas and kennel clubs the Miniature American Shepherd is still used as a working breed in competitions.

The predecessor to MASCUSA was the North American Miniature Australian Shepherd Club of the United States, NAMASCUSA and was the first Parent club registry for the Mini Aussie. The second club to register Mini Aussies Miniature Australian Shepherd Club of America MASCA is currently active but no longer accepts dogs registered as MAS with AKC. AKC MAS dogs may still breed to Mini Aussies however.

In 1993 the original MASCUSA club was asked by the AKC to change its name. Additionally, Miniature Australian Shepherds could no longer participate under their chosen name as it was too similar to that of an AKC affiliated breed, so the Miniature Australian Shepherd was renamed the North American Shepherd.

Every pet is one of a kind. This guide covers what's typical for the breed, but your own dog or cat will have their own personality, quirks and needs — think of it as a friendly starting point, not the final word.
