I agree with the lunging thing, it's not really convient..and then if you're at a rodeo or show and you can't lunge for whatever reason you're stuck..She'll become used to it and maybe depend on it.
It could be that she's still young and goofy..hasn't figured out everything yet.
Yeah...I'm sure we'll figure her out!:P Rosie has acted this way before, but that's more enjoyable. Who doesn't enjoy a hyper 21 year old?! At least when she does it, you can controll her. Posted via Mobile Device
My old horse acted up at shows sometimes. To her attention I brought her down to her slow little english trot and made her collect up. I just did that until I knew she was listening to me. Or sometimes just let her canter circles until she wore herself down, that was when she was alot younger though. She mellowed out the older she got. Ever try a calming supplement? Like Mare Magic or Quitex. Its not a drug, just knocks the edge off them. My mare got Quitex at big shows and rodeos until she got over the noise. Posted via Mobile Device
I haul her maybe twice to three times a month to the same arena. She's been to the arena hundreds of times and was going every single week last year. The rodeo and barrel race I took her to were in this arena..
She's about the same at home, except I can get her energy out troting and loping in the round pen, since I don't have an arena and I just ride all over my pasture. Posted via Mobile Device
What I do with chargy horses is that I take them into an arena that has no barrels or anything in sight and just make them work on them stopping/slowing and listening to my seat besides my hands. If you do this enough times, the horse will figure out that s/he doesn't have to run the whole time when around an arena. It doesn't happen immediately but if you do it enough times, it gets into the horse's head.
She hasn't been on the pattern enough to be excited about seeing the barrels, and when I go to the arena I don't set them out until she has calmed down. Posted via Mobile Device
What do you think of this bit maybe? I like the sliding gag action but it's not over the top, and the fact the mouth price isn't too much different than a snaffle. Do this bit require a curb chain? Posted via Mobile Device
I don't think a bigger bit is going to help you especially if you can control her in snaffle when she does this. Sounds to me like needs more time with basic training and bumping up to a leverage bit may just make things worse over time. Just a thought but could it be your saddle fit or her teeth that bother her when you first mount up? Are you anticipating her doing this and maybe tightening up a little causing her to react? If she is 21, this may just be a learned habit and will take more time to work out of her...
