How to fix a horse that is overbent even at a walk?

A horse that is overbent — carrying his nose significantly behind the vertical, curling his neck inward, and bringing his face toward his chest — is one of the most common results of well-intentioned but incorrect training. The overbent horse at the walk is a particularly clear signal that the problem is deeply established, because the walk requires the least collection and the least rein contact — a horse overbent at the walk has learned to carry himself in that position as a default rather than as a response to specific rein pressure. Overbending looks like submission but is actually the opposite — the horse has found a way to avoid the conversation entirely while appearing to comply with its surface form. In true collection the poll is the highest point and energy travels forward through a lifted, swinging back and soft neck to a light contact at the bit. In overbending the horse has escaped that contact by ducking behind it — the reins are loose, the contact is meaningless, and any communication through the rein has been circumvented. The cause of overbending is almost always training that relied too heavily on draw reins, side reins set too short, or strong rein pressure that rewarded the horse for getting his face behind the vertical. A horse trained with draw reins learns quickly that the shortest distance to release is behind the vertical — the more he curls, the more slack appears in the draw rein. The retraining begins with removing the equipment that created the problem — working in a simple correctly fitted snaffle with direct rein communication. Forward is the first correction. The overbent horse needs to be ridden strongly forward off an active leg onto a following hand that maintains a soft elastic contact and does not reward the horse for curling behind it. Think of riding the horse's hindquarters out from under him rather than pulling his head into position. Long-and-low work is the specific technique most directly targeted at overbending — asking the horse to stretch his neck forward and down in response to an invitation from an opening, lowering hand. Soften both hands downward and forward, not throwing the contact away but opening the fingers and allowing the reins to lengthen as you invite the horse to reach down and forward. The timeline for retraining established overbending is measured in months rather than weeks, and the temptation to use stronger equipment to pull the horse's head up should be resisted completely.
