I ride my 21 yr horse in a english loose ring snaffle with the bars being thicker. The other day, I had to do a lot of one rein stops because it was near feeding time and I was riding him in the arena with the gate open and he would run out at the trot and not paying attention to me and would practically run into the wooded fence because he was trying to get out instead of turn the curve like I wanted. I tried to turn him to prevent him from going out and that is when we would just about hit the fence and he'd use that to his advantage to scrape me against the fence. So, we'd be out.
And he'd rush out to the barn (trot) and I did the one rein stop to get him to stop and he'd finally listen to me. He fought me for a few seconds on that, but we got through it. I turned him in a circle to go back to the arena and he'd turn and go the other way but I'd get him back to the arena. Then, I'd circle him in the arena at the walk and get him listening to me, which he was. He did it good, turned and walked nicely. Then, we'd get close to the arena exit and he'd run out again with me still preventing him from going outside and didn't have enough time to use my crop that I had with me. So, did more one rein stops. But finally, I got him to do two large circles in front of the arena. He did good, walking past the entrance and not turning around to the barn, but kept on the circle. Then we went back inside the arena quietly, and then did two large circles by the arena exit and then we walked back outside. And then he did fine. Before I dismounted and I turned him around and walked toward the arena and then dismounted. He's a little food oriented.... Of course when I had my instructor to ride him at the same time two weeks ago, he didn't do any of that. Did perfect. And he does lessons with kids, and does perfect...I don't let him get away with stuff like that but it's annoying how he keeps doing it to me every time. Any tips with what to do, or if I did wrong, or anything? And I wasn't scared I sang out loud and was fine ! Happy about that.
