He's beautiful, but seems like he can be a handful. What bit are you using? The reason I ask is because I have one that runs through the bit at times; mine prances like this and wants to GO no matter where we are or what we are doing (not just barn sour!) Does he rear on you? Mine hasn't but I have often wondered if he might...
In this video he was using a simple o-ring snaffle. Because he was tearing his mouth with the tom thumb and my wonder bit. Jake ran through the bit, a lot during this time period. Yes he also reared, quite a bit. It really is avoiding the first rear, once Jake reared once out of frustration of being held back and he kept on rearing after that and it has been 'heck' trying to get that under control. At the time it got to a point that Jake was like the video every time I wasn't in an arena, it didn't matter where I was going. But the bit wasn't close to being the issue, only reason I have a stronger bit is the mechanics of it lift up his shoulder when I'm riding western, not to slow him down. If you go more powerful on a horse that was acting like Jake was, your asking for the rear instead or avoiding it.
trailhorserider - Could be he is making it up just be moving around. But he'll do it like that when hes more relaxed as well...this is the only clip I have though. Lol Yeah that what everyone thinks, but it was beyond getting out energy. He would do what he was doing until his heart gave out of pure exhaustion. I would be trying to get him to walk around (no hills or anything) and two hours later he is dripping sweat, tripping because he is so tired and still prancing and throwing himself around.....getting the energy out isn't an option.
Juna - Okay I guess that may have been the right term then. As I was telling trailhorserider round pen work wouldn't have done anything. He was 19, dead calm on the ground and is I turned him out he would find the nearest shade and sleep. It wasn't that he had too much energy, just bad training before I got him. He was used as a trail galloper, take out, gallop out, gallop back, put back. So he didn't really know how to relax on trail (still doesn't) and when I told him he needs to walk he became so frustrated that he started this habit of prancing and bouncing around. Round pen work didn't change anything other than make him trip more because he was tired before I got on.
