Instructions
Stand the horse up squarely on level ground, and measure the height from the ground to the withers. If the horse stands 38 inches or less at the withers, it is a miniature breed.
Look at the horse's appearance, starting with the head. If the horse has a thick jowl tapering to a small muzzle, with short ears and a broad forehead, it is likely to be a Shetland or a horse with a proportion of Shetland or other pony blood. The legs of such a horse will be relatively short in proportion to its body, and the horse may have a slightly pot-bellied appearance.
Continue to examine the horse's mane, tail and legs. A horse with thick, bushy hair will have a lot of pony ancestry. Horses with finer, silkier hair will have Arabian or thoroughbred in their pedigree. If the horse's legs are in proportion to its body, and it resembles a miniature horse in its conformation and appearance, it is likely to be an American miniature horse.
Check the horse's coloring. If it is a pinto or appaloosa, there is a chance it is a rare breed of miniature horse, the Falabella. These horse also come in solid colors, but broken colors predominate. They also tend to be smaller than American miniatures, often standing only 32 inches high. There are only 1,500 Falabellas registered worldwide. All purebred Falabellas are registered with their breed society, so the ancestry of individual horses can be traced.
