We're showing lntro level right now, but working on leg-yields, shoulder-in, haunches-in, etc. He isn't ready for much more right now :). She isn't putting together a whole freestyle, just choosing music that will help you with issues like rhythm, relaxation, etc. No, he's not a dressage horse, but l enjoy it and it helps him immensely, so that's what we do with a day or two a week of jumping :). At his old barn (the first 9 or 10 years of his life) he was ridden in a twisted wire snaffle from the time he was started, so when he was put in the eggbutt snaffle at my barn, all of his training issues resurfaced, and it really helps him to have consistent dressage work instead of just jump, jump, jump. Hoofers is mainly a h/j barn, but there are three or four mid-level dressage horses who are used in dressage lessons with those instructors.
Most of the riders that l know who are doing this clinic don't specialize in dressage; they are using it to help them with training issues.
