See the saddle scars? The white flashes of hair indicate the nerves have died. This is likely the result of having to cinch too tight to keep the saddle from crawling up onto his shoulder blades. A rump high horse can make the rider feel pitched forward. Being a saddlemaker, I don't recommend this type of conformation. If you still go ahead and buy this horse, I strongly recommend you get mule breeching, sometimes called spider breeching which through a number of straps around the horse's hips spread the pull of holding the saddle from crawling forward.
