I bought this horse specifically because my riding instructor knew the horse when he was younger. He is a reiner, however we haven't made it to any reining manouvers in the six short months i've owned him. He was a researched purchase as I thought I knew what kind of horse I was getting, however in the few years from when my instructor knew him to when I bought him, he seems to have changed. I know the last few years haven't been easy on him, and some of the owners pervious to me have been hard on him. He seems to have a hard time focusing and seems to just be worried all of the time. He is currently at my tainers barn, because I'm a relatively new rider and need help working though some of his issues. I was just wondering if anyone had any advice or have dealt with anxious horses before? I've been doing lots of ground work with him and realize that I haven't owned him long. Any advice is welcome!
