The Miniature American Shepherd is a medium-sized herding breed originating in the United States. It is known for being intelligent, energetic, devoted, loyal, eager to please, and work-focused. The breed has a medium-length coat that can be straight or wavy, and it sheds moderately. Estimated adult weight ranges from 9 to 18 kg for both males and females, with estimated height between 36 and 46 cm. Lifespan is estimated at 12 to 13 years. The breed's recognition status varies by registry. Individual temperaments may differ, but the breed is generally described as having high energy and trainability.
The Miniature American Shepherd was developed in California during the late 1960s from small Australian Shepherds, bred for compact size while maintaining herding ability. The breed became popular with equestrians traveling to horse shows. It was recognized by the AKC Herding Group in 2015, though recognition status varies by registry. The breed's origins are in the United States, and it belongs to the Herding group. The exact details of its early development are not fully documented, but it is essentially a smaller version of the Australian Shepherd.

Owners should use routine preventive veterinary care and discuss screening appropriate to the individual dog's history, examination and family line.
