This horse has mandibular brachygnathia, i.e. its upper jaw is longer than the lower. The horse's teeth are continuously growing in order to compensate for the permanent wear caused by chewing grass. Since the jaws are out of place, the staggered incisors do not wear out and press through, badly hurting the horse.
