A horse has a total of 18 digits across its four legs. Each foreleg has 5 digits, while each hind leg has 4 digits, but horses primarily bear weight on one digit per leg, which is the hoof. The other digits are represented by vestigial structures, with only the third digit being functional as the hoof.
