Why does my horse buck and how do I stop it?

Bucking has causes that range from physical pain to green horse exuberance to a confirmed evasion, and identifying which category you are dealing with determines the correct response. A horse that has recently started bucking after previously being quiet should be evaluated for pain before any training correction is applied — saddle fit, back soreness, ulcers, hind end discomfort, and girth sensitivity are all common physical triggers for bucking that will worsen if addressed only as a behavior problem. A horse that bucks when first asked to canter, when cold, or on fresh mornings in spring is often expressing high energy rather than genuine resistance; more turnout, a longer warm-up, and progressive conditioning reduce this type without confrontation. A horse that bucks in a specific location, at a specific gait transition, or when a particular aid is applied is telling you something precise — pay attention to the pattern because it points to the cause. The training correction for a confirmed bucker involves keeping the horse's head up, since a horse cannot buck effectively without lowering its head and rounding its back to generate the movement. When you feel the horse begin to prepare — the back rounds, the head drops, the stride shortens — ride forward immediately with leg and pick the head up with a direct rein before the buck develops. Circles and changes of direction also interrupt the sequence. Never pull back and sit still when a horse is about to buck; that positions you perfectly to be unseated and does nothing to stop the movement.
