What should you do if a horse jumps over an obstacle instead of walking through it?

A horse that jumps an obstacle rather than walking through it carefully is trying — it understood that the obstacle required some kind of forward effort and it offered what made sense from its perspective — and that try should not be punished, criticized, or treated as a failure. Jumping instead of stepping is almost always a communication and understanding issue rather than a willingness issue: the horse has not yet learned that deliberate, careful foot placement is what the obstacle requires, and it solved the problem of getting past the obstacle in the way that felt safest and most natural to it. The correct response is to calmly circle back without drama, set the approach up again from a greater distance, and give the horse time to examine and process the obstacle before reaching it. Slowing the approach pace significantly helps: a horse approaching an obstacle at a brisk walk or trot is more likely to jump because the momentum carries it into a jump response, while a slower approach gives the horse time to slow down, lower its head, and look at what it is stepping on or through. Ground poles arranged as guides on either side of a low obstacle teach the horse that the path through the obstacle is straight and narrow rather than requiring a jump to clear it. Work from the ground first specifically to establish the concept of stepping rather than jumping: leading the horse through ground poles on the ground, then over a single low pole, builds the foot placement awareness and the understanding that careful stepping is the expected response before the same obstacle is introduced under saddle where the rider's position and weight make corrections more complex. Patience with a jumping horse pays dividends quickly — most horses that jump obstacles understand the stepping expectation within a handful of correct groundwork sessions.
