People, I don't think you understand, but my horse IS trained, I can ride on the trails or on the side of the road literally all day on him, and he'll still lope figure eights or run a pattern for me at the end of the day. I can get him to back, go through all his gaits, side pass, trot a circle and make it bigger/smaller by using legs only, ect. In the pasture, my round pen, or in a regular uncovered arena. I had my trainer ride him in my lesson a few weeks ago, and we switched horses, and I found out he was knew way more than I thought, and he was trained to do a lot of things, I just wasn't giving him the right signal because he was taught a little differently than any of the other horses I've ever ridden. I can get him to do all of things with or without the use of spurs or a crop.
I don't know anything about this horse's owners before the lady I bought him from, training, or riding experiences. I only know that the person that owned him before me had him about a year, rode him in only an O-ring snaffle, didn't hardly ever trailer him anywhere, and only did a little riding around her house and in her pasture. She was a good rider, and knew a lot about what she was doing, and had three other mares he didn't get along with, and she sold him because he was lonely and pastured alone, and didn't get used enough.
It sounds like I led you to thinking he always acts like this, or that he's completley dangerous , hyper, and way too much . He's not.
