Thanks guys! I think I'll give it a shot. The thing is, I'm not sure how much his back actually bothers him... Ryle - Tuesday was the second full lameness exam he conducted. His sore spot is about three inches from the cantle of my saddle, so I'm pretty sure its not the saddle. Also, I went on vacation for two weeks and he was the exact same amount of sore as he usually is. I can't actually tell if it affects him normally (I imagine it would), but he is sensitive to pressure (me running my fingers along his spine). We did find a slight curvature, so that is the likely culprit. While we try to fix it (with the chiro and "physical therapy" - ground poles, cavaletti, etc, to strengthen the rest of his back), I think the DMSO might help. I will def. use gloves though! lol. Cowgirl - that is a great idea with the Aloe. I never thought of it! Thanks again!
No problem! Good Luck! It sounds like you are doing all the right things tho.
