An impressive athlete in a small package, the Miniature American Shepherd (MAS) is energetic, agile and adaptable. A clever, medium-sized dog, the MAS has the heart of a ranch dog in the body of a house dog. Completing any job with style and enthusiasm, this highly intelligent and willing-to-please dog requires daily physical and mental exercise.
Once a part of the Australian Shepherd breed, the MAS split from the Australian Shepherd Club of America to form its own breed in 2011.
The breed originated in the 1960s in California.
