The Miniature American Shepherd Club of the USA (MASCUSA) was selected in May 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 the original parent club for the Miniature Australian Shepherd. MASCUSA represents AKC Miniature American Shepherd breeders and owners across America and around the world.

The breed standard for the Miniature American Shepherd can be found at MASCUSA Breed Standard.
