Dear Cassie,
Your situation doesn't sound too good! I would want to be sure that your
horse doesn't have some kind of veterinary or chiropractic issue before I
started trying to correct any training problems. Once you have eliminated
any issues of soreness or pain, then and only then, can you think about
retraining. And if he doesn't have some sort of pain or soreness, then you
DO have a very large problem that will be hard to overcome. It will take
lots of time NOT competing and making runs but instead doing slow work and
lots of scoring in the alley and gate.
