Well not to be like the ol' cowboys that beat a horse... not what I'm looking for just to have you're control back. This could be just doing a simple circle or doing one at a trot, keeping the circle small so its harder for the horse to work.
Usually that's what I do when my horse isn't acting properly and they get the hint that when they act up we go back to circles but circles are hard work, so pretty soon they figure out if they don't act up they don't have to do circles.
I think that any horse should be able to go on a trail ride, that's important to me I think mostly because the horse I had was horrible on them, and now I have this really calm horse when I get out on the trail that I love it. And omg all the obsticles you can take them through on the trail, its a really good experience. So that when you go to a show and a jump is set up on top of a hill ur horse has confidence going up it, or going through some water or working out the spooks in scary parts. It all builds confidence so you can get to that horse that never refuses a jump.
Ok now I'm just rambling. So mainly when you're horse is acting up go back to basics, work that trail like ur back in the arena and do what you do best. Be that leader that knows where ur going and whats around that next corner. Horses rely on us more then we think, and they feel when we're not confident so these trails are good for both of you.
Of course its not as easy as it sounds, not for alot of horses anyway, but u'll get to it someday, and it might not happen on this trail ride, maybe u'll have to try it again soon, but its all a process and you just have to work with it. Hope this helps! I'm not sure if I'm getting my point across lol.
