Most of the time I sponge with the reins (squeezing alternate reins). My instructor told me it will help to get Night Heat to soften with the mouth and get her to take the contact. It works well in trot, but in canter even when I squeeze relax squeeze relax, all it does really is brings her head closer to the vertical (evading the bit) and she still goes her fast pace.
When she goes faster towards home I sometimes do a circle or two, which usually gives her abit of time to think and she slows down just a little bit in pace. I guess that's abit of progress, right? I will also try turning her around or backing up when she speeds up.
Another thing she tends to do is when cantering away from 'home' she sometimes drifts to the outside, and since the arena has no fence she goes all the way to the outside. What I do when she does this is give a tug with the inside rein and kick with the outside leg behind the girth. Not sure if this is right, but it gets her to turn her whole body so its facing the inside again, then we carry on as usual.
Northern: My instructor has gotten me to do that, just cantering around and around doing circles and serpentines, until she starts to relax abit or as my instructor puts it "until the nuts and bolts are back in place again". I have also heard of the spiraling in and out, but haven't really tried it. Will check it out this weekend.
SPhorsemanship: She is about 15 or 16. It may be a balance problem, because I have heard that when they are unbalanced they tend to go faster.
I always tell myself to breath deep and try to relax my whole body when Night Heat is having one of her crazy moments. I find it quite difficult, especially when she is so tense and tearing around the arena, but I'm getting there slowly.
The second step you added is what I usually try to do with Night Heat to get her to use her hindquarters. The days that she is feeling really hyped up, I leave out the canter and just do halt-walk-trot-halt-trot....etc. It also helps to get her to relax her neck and jaw, taking the contact up.
Wow, I didn't realize how long this post was. I apologize again, I truly get carried away.
Thanks a ton so far for the advice.
Any more exercises I could try with Night Heat? Any to help myself as well?
Will post a video tonight.
