Since I'm visiting my dad over the summer I can't get to my horses, but when I return in late August I'm going to start practicing with my 6 year old for a dressage show. Nothing series, and I haven't even decided what class I'll do, probably some introductory level. Anyways, we have a few months to practice and I want to be prepared as possible, so do you guys have any good exercises for us to do that will really help him be responsive, supple, relaxed, and give him a little brain work? It can be for riding or groundwork. Please share! He's a very talented young horse and me and him could go far yet.
