I recently started taking dressage lessons. Before I was riding quarter horses western pleasure and occasionally hunters. I've been riding for a looooong time, and I'm usually comfortable at all three gaits. When I went for my lesson last night though, I got really tense when we started cantering. It felt like I was almost being run off with. I know that really isn't the case. I'm just used to riding 15 hand horses going extra slow, as opposed to the 18 hand Thoroughbred I was on last night.
Any tips for relaxing at the canter and getting used to the bigger stride?
