Final answer:
A pigeon-toed horse typically exhibits a trappy gait, which is a shortened and more rapid stride that can be uncomfortable for the horse and inefficient compared to other gaits.
Step-by-step explanation:
The gait exhibited by a pigeon-toed horse is typically referred to as a trappy gait. A pigeon-toed stance, where the toes point inward, can lead to a shortened and more rapid stride. This kind of gait is often uncomfortable for the horse and may affect its ability to move smoothly. It is different from a smooth gait, which is efficient and easy for the horse, a limping gait, which indicates an injury or discomfort, and a galloping gait, which is a fast, four-beat rhythm typically seen in a full sprint or when a horse is covering ground rapidly, which was demonstrated by the thoroughbred bay mare "Annie G." as captured by Eadweard Muybridge in 1887.
