Now I use my twh for walk, trot, gait, canter, and gallop. He knows the cues to go into which one pretty well except for trot or gait... still working on that. He would rather trot then gait. But at any speed he won't extend himself. At all!!! Even if I am riding with someone and there horses who have great extensions. He could care less to follow them. He will fall back so far in the ride that I am constantly trying to catch up with everyone. Unless we are on the way home that's when he will finally show the extensions I want.
I have no idea what to do. The trainer I have hasn't seen any improvements with her methods of circles and changing things up. So I was wondering what else to try. He extends on his own in the field and when asked on lunge line or in round pen. Just won't extend when riding. I have checked saddle fit and chiro has come out, vet has says nothing is wrong and farrier says there is no lameness. So pain can be eliminated... any idea??
