Trot

The diagonal hooves lift off from and hit the ground at the same time. The sound is a 1-2 beat. Horse does not nod his head. The whole body lifts and falls, but the hind quarters remain steady. The hind hoof will track on the front of the same side. It can range from the feel of the jog to the teeth jarring impact. Gaited Morgans might perform the trot gait.
