Yea we have been working on her being a pain on trail for the last few months, however the issue is, that she LOVES to run. When we go for trail rides, it's generally my boyfriend and myself. When we go riding, I ride Bree and my boyfriend rides a nice paint. When we take the two together, they are great and there is no issue as long as we don't run. My boyfriend ALWAYS runs his horse down this flat grassy area and when he takes off, I have a hard time keeping her calm because she wasnts to run too. So the gag and tie down are required. The few times that he rode her, I didn't run the other horse at all, we just sort of trotted, but not for long and she was perfect. So I'm not really sure how to break her of wanting to run when the other horse runs. I'm not terribly experienced, but can stay on and handle her.
