My daughter works at a reining barn and we both ride English. She is currently training our pony cross filly as a potential eventer. (Right now she is in the very early stages of training). After watching a reining clinic at work, we are wondering if cross-training in other disciplines is a good idea. We really like the softness and collection we see in the reining horses and wondered if introducing some of the techniques used would provide any benefit to a potential eventer?
