arthritis in back end, I want to do a littl? in the back end. I would be doing the odd trails, mostly flat and no more than walking as I am an elder too!!! I had a friend try him out a little and he he so sweet and laid back and she said she could hear clicking and felt he was a little weak on the back end, He seemed to buck ok and run up and down the hills in his pasture. What would be the best for him to help the arthritis from getting worse?
