Chiilaa, I totally agree with you. His back is extremely flat. Our saddle fitter had a heck of a time trying to find something that worked, and we ended up having to go with a custom made tree and panels on his saddle... He does naturally want to leave his hind end trailing out behind him and dive his head down so that he has a straight line from nose to tail. In this week's lesson, we taught him how to bend through the ribcage and contract his abs for the first time in his life. He actually had that awesome lift working through his back so I'm anxious to see if this new way of going changes the shape of his back at all. This was also the first time he really stepped under himself with his hind legs. But, for the type of dressage work we're doing, I don't expect it to be too much of a hinderance, especially since we're training for his health and not training to compete. I *think* that's what most people are referring to when they say he made a better hunter in his day than if he had been expected to be a high value dressage horse. I imagine upper level collected work would be nearly impossible for him.
