How do you train a horse to make a correct fence turn?

Training the fence turn begins with the physical components — the stop, the rollback, and the controlled acceleration — that must be confirmed in the reining foundation before cattle are introduced into the fence work training, because the fence turn is essentially a rollback executed in response to the cow's position rather than the rider's predetermined timing. The first stage of fence turn training introduces the horse to the concept of tracking a single cow down the fence at a controlled rate, building the rate-behind-the-cow skill before any turning is asked. Once the horse can rate correctly behind a cow moving down the fence without being prompted for every pace adjustment, the next stage introduces the acceleration cue — asking the horse to drive past the cow's shoulder to get into position — using a clear, specific cue that the horse learns to associate with driving forward past the cow rather than continuing to rate at the cow's pace. The turn itself is first trained at slow speeds with cooperative cattle that do not outrun the horse, allowing the horse to learn the sequence of accelerate past, plant, roll back, and drive without the additional pressure of racing a fast cow. As the horse learns the sequence and begins to anticipate the turn from the cattle context rather than waiting for each individual cue, the trainer allows the horse to take more responsibility for reading when to accelerate and turn while reducing the explicitness of the aids. Common training errors include pushing the speed of the fence work before the turn mechanics are confirmed, using cattle that are too fast for the horse's current turning ability so the horse is perpetually behind rather than getting ahead, and over-cueing the turn so the horse never develops the instinctive acceleration that produces the best fence turns.
