A pony is a member of any breed of horses (Equus ferus caballo) that are small in size as adults. Most ponies tend toward stockiness, with shorter than average legs, wider bodies, and heavier bone structure, although there are exceptions. They often have thicker manes, tails, and coats than other horses. Not all small horses are necessarily ponies; the smallest breed of horse, the miniature horse, is generally not categorized as a pony.
