Mule/Hinny

Equus caballus x Equus asinus

Mule and hinny are closely related equine hybrids from horse and donkey parents, but the parent direction differs. A mule comes from a donkey sire and horse dam, while a hinny comes from a horse sire and donkey dam. Both are usually sterile and can show long ears, tough hooves, strong bone, and a cautious temperament, although size and build depend heavily on the parents. Hinnies are less common than mules because the cross is harder to produce and the donkey mare's size limits the foal more directly.

Care and training for either hybrid should start with the individual animal rather than assumptions about the label. Many need patient groundwork, careful hoof and dental care, well-fitted tack, and handlers who understand donkey influence in learning and self-protection. Mules are common in trail, pack, driving, and ranch work, while hinnies may be kept by enthusiasts who appreciate their rarity and quieter build. Breeding programs must maintain suitable horse and donkey parent stock because hybrids generally do not continue the line themselves. Purchase records should make the parentage clear.
