The Miniature American Shepherd is a small size herding dog that originated in the United States. He is slightly longer than tall with bone that is moderate and in proportion to body size and height without extremes. Movement is smooth, easy, and balanced. Exceptional agility combined with strength and stamina allows for working over a variety of terrain. This highly versatile, energetic dog makes an excellent athlete with superior intelligence and a willingness to please those to whom he is devoted. He is both a loyal companion and a biddable worker, which is evident in his watchful expression. The double coat of medium length and coarseness may be solid in color or merled, with or without white and/or tan (copper) markings. He traditionally has a docked or natural bobtail.

The Miniature American Shepherd is intelligent, primarily a working dog of strong herding and guardian instincts. An exceptional companion, he is versatile and easily trained, performing his assigned tasks with great style and enthusiasm. Although reserved with strangers, he does not exhibit shyness. He is a resilient and persistent worker, who adjusts his demeanor and arousal appropriately to the task at hand. With his family he is protective, good natured, devoted and loyal.
