My horse is drifting to one side when going over fences how do I correct that problem?

A horse that drifts consistently to one side over fences — that leaves the ground on a straight approach but lands several feet to the left or right of the center line — is a common and frustrating jumping problem. The effective corrections happen on the ground and in the approach rather than during the jump itself, which is where most riders instinctively try to address the problem. The first distinction to make is whether the drift is primarily a horse problem, primarily a rider problem, or a combination of both. A horse that drifts consistently to the same side regardless of the rider is more likely a horse problem. A horse that drifts differently with different riders is more likely a rider problem — an asymmetry in position, a collapsing hip, or an unequal leg that is steering the horse off-line without the rider's awareness. Video and observation by a ground person are essential for making this distinction honestly. For a horse-side drift, the physical causes worth investigating include asymmetry in the horse's muscular development, vision limitations, and hind limb discomfort that causes the horse to push off more powerfully from one hind leg and drift in the opposite direction. Veterinary evaluation of any consistent hind limb asymmetry is appropriate before correction work begins. The training correction for drifting uses placing poles and guiding rails to create a physical channel that the horse must jump through rather than around. A pole placed on the ground along the side toward which the horse drifts — positioned to create a physical barrier the horse must avoid — encourages straightness through the fence. Wings on the fence extended closer to the ground on the drift side create the same channel effect. These physical guides work without requiring the rider to correct the drift during the jump itself. The approach is the most rider-controllable phase of the entire jumping process. A horse that arrives at the fence straight, with equal balance on both sides and a centered approach line, has the best possible setup for a straight jump. Establishing and maintaining absolute straightness in the final strides — confirmed through video rather than assumed — addresses the drift at the moment it is most correctable.
