My lease owner has 2 horses. One she calls her school master, the other one is a bit hot. She says he has a tendency to get excited under saddle, gets ancy when not in the front on a trail, doesn't like being alone on a trail, tries to run home once getting back, etc.
I've ridden a horse that gets excited at a trot/canter, and have some experience in that, but not when it comes to trails. I have the knowledge, but no experience.
Before I think of riding him, is there any specific ground work I should do? What can I do in the saddle to help calm him? I know keeping my body relaxed is one component, but what about anything else? They aren't fed anything to make them hot, it's just his temperment I think.
