The horse might have heaves or some other respiratory ailment. Ask why straw was not used. Stall walkers are hard to cure. Even the manure can give you a clue to the horse's health and the condition of teeth. If excessive long straw or hay and whole grain appear in the droppings, the horse may need some dental work.
Health records Consider the horse's general health.
Most horses purchased should be tested and shown negative. Feet, legs and action Observe the horse carefully as it is led from the stall. Be on guard for even slight indications of limping, stiffness or the favoring of a leg or foot. Examine the feet and legs with care. Since a horse is no better than its underpinnings, sound feed and legs are vital.
