Small sized dogs which were speculated to be Australian Shepherds were instrumental in the development of the Miniature American Shepherds. In fact, the Australian Shepherds that worked in the rodeo circuits of the U.S.A were bred selectively to bring in a reduction in their size but maintain their active disposition and intelligence.

Initially registered in the year 1980, under the National Stock Dog Registry as the Miniature Australian Shepherd, the new breeds emerged as great travel mates for the equestrians heading towards horse shows, with their small size, intelligent demeanor, and loyal nature. Gaining popularity by the first half of the 1990s, these breeds began to be promoted by several clubs. As several Australian Shepherd enthusiasts objected to these dogs’ association with their breeds, the name was initially changed to the North American Shepherd and ultimately the Miniature American Shepherd. The MASCUSA (Miniature American Shepherd Club of the USA) established in 1990 and came into function in 1993 is the national parent club of this breed as designated by the AKC. The American Kennel Club registered it in its FSS (Foundation Stock Service) group in the year 2011 and also acknowledged MASCUSA as the member of its herding group in 2015, July.
