I would not recommend using hobbles to prevent a horse from pawing and getting excited around feeding time. There is a simple and humane solution to eliminate the behavior that will take only about seven feedings and a fair amount of patience. Right now the horse is being rewarded for pawing, as he is fed when he is pawing. Simply wait until he ceases pawing, and use that moment to cue the correct behavior by feeding him. He will learn quickly that the way to “turn on” the food is to stop pawing. Be patient, though. The behavior will get stronger at first, because the horse will be frustrated that the pawing behavior is no longer producing food. He will paw more, and harderso just take a deep breath, relax and wait. Thanks for the question, Claire.
