I put my ottb in side reigns (months after I got her) and she was so funny. She kept backing up all over the arena ... they weren't tight at all but as soon as she went to put her nose down the little tension that there was caught her. I started to walk away from her hoping that she would follow me, because she will follow me anywhere, and she tried it and once she put her head down she would back up, go forward, back up ect... but after about 3 or 4 min she got it and now is perfect in them. Also the lounging thing is hard for them to get, it took her a while but she is amazing now. Good luck and keep us posted!
