More: A Miniature American Shepherd is a Miniature Australian Shepherd. When the AKC accepted the breed for showing they called them Miniature American Shepherd. Extremely smart, resourceful, loyal puppies they are. Clowns, butt wiggles, always thinking. At 40 lbs, he is my favorite medium dog! Loves adventure and currently travels around the country in an Airstream. He has been to many places in his little life! He loves it!
