The American Miniature Horse Registry is the original registry for the Miniature Horse in the United States. Registering as many as 10,000 horses each year and hosting an annual national show, AMHR recognizes two sizes and is the most comprehensive small equine option.
Division "A" Miniatures are up to 34" in height while the Division "B" Miniatures are between 34" and 38" tall. Unlike the majority of most equine breeds, miniature horses are measured at the last hair of their mane rather than at their wither. Miniature horses come in a full spectrum of coat colorings and patterns and (unlike Shetlands), a spotted appaloosa is an accepted and popular coloring in the American Miniature Horse Registry.
