I do dressage. I would be like, yay, the horse is trying to be forward, the horse has some energy, and I'd be encouraging her to go MORE forward so that instead of just moving her legs fast or bouncing(which is not really going forward but is some kind of messed up but rescue-able forward urge), she could open up her whole body and use her hip and shoulder and back a whole lot more. Time to go gallop the horse and really get her using her whole body, like when Christoff Hess was teaching people and they thought they were going forward and they weren't. Go more. Maybe Western Pleasure is not appropriate for her. Nothing I like better than a 'busy minded horse'.
