I have had him for several years now. He was originally trained in reining but I am working him towards english and possibly jumping 18" cross rails. He is currently used as a lesson horse. Just let me know what you think!
Sorry for the lighting and bad stance, we were in a hurry. I will try to get better pics tomorrow.
You can help his back with Caveletti and trotting up hills with you in a two point and him lon a loose rein. Gradually raise the caveletti to 12 inches and 8 poles and again.. two point on a loose rein.
He is really a pretty nice horse.. solid and it looks like he has a correct hind leg. Get his abdominal muscles built up so he can better support that back. When he is in better shape and can do caveletti like I have indicated (3-4 months from now with regular.. 5-6 days a week riding) and trot up long hills (if you have hills) he probably will be fine with small jumps.. and 18 inches is small jumps.
