Small, but strong, the Miniature American Shepherd is known for his stamina, intelligence, athleticism, and docked or natural bob tail. The head is clean and strong with a flat (or slightly rounded) top skull and a slightly tapered muzzle. The teeth meet in a scissors bite; the almond-shaped eyes are expressive and intelligent. The triangular ears should be set high at the side of the head.
The Miniature American Shepherd is slightly longer than tall, with bone that is moderate and in proportion to body size and height, without extremes. The neck arches slightly at the crest, the topline is level, and the whole body is firm and muscular. Front pasterns are thick and strong; hocks are slightly bent. Both rear and front feet are oval, compact, and have close-knit, well-arched toes.
The weather-resistant double coat is of moderate length and coarseness. The top coat can be straight to slightly wavy, but hair on the head, outside of ears, front of forelegs, and below the hocks is short and smooth. There should be some feathering on the backs of the legs; hindquarters have fuller feathering than the forelegs. Male dogs have a more pronounced mane and frill than females. Accepted colors include blue merle, red merle, solid black, and solid red. White markings and tan points are acceptable, but the areas surrounding the ears and eyes should not be white.
The Miniature American Shepherd's gait should be smooth, balanced, and agile, easily covering ground.
Small Australian Shepherds (less than 18 in.) have existed since ranchers in the Western United States first started importing sheep (and herding dogs) from Australia in the late 1800s. The ranchers bred the "little blue dogs" from Down Under to their own herding dogs, creating what we know today as the Australian Shepherd.
Breed historians believe that, over time, ranchers bred the dog to be larger, so that it could more effectively handle cattle. But historical photographs show that ranchers have long owned smaller-sized "Aussies," today called Miniature American Shepherds. A deliberate breeding program didn't begin until 1968, but throughout the 1970s and ’80s, a handful of breeders took up the cause of breeding smaller Australian Shepherds that could still work stock, but could also be companion dogs. They were first registered with the NSDR (National Stock Dog Association) as Miniature Australian Shepherds. Dogs less than 13 inches were registered as Toy Australian Shepherds.
In 1990, a handful of those breeders created the Miniature Australian Shepherd Club of the USA (MASCUSA). The name was changed in 1993 to "North American Shepherd" to comply with the rules of the American Rare Breed Association, the only show venue open to them at the time. As the larger Australian Shepherd had been recognized by the AKC, ARBA would not allow the Miniature Australian Shepherd to show using the AKC name. In 1998, ARBA changed its policy and the breed's name changed once again, this time to the North American Miniature Australian Shepherd. Later it was again shortened to the original name, Miniature Australian Shepherd.
In 2011, the Australian Shepherd parent club allowed the breed to separate into two. The smaller size entered the AKC FSS program under the name of Miniature American Shepherd. It quickly advanced to enter the AKC Herding Group in July 2015.
This diminutive version of its full-bodied cousin is increasingly popular—not only for its intelligence and athleticism, but also as a house dog and family pet. The dogs excel at canine sports such as agility, obedience, flyball, and disc.
