Maybe I have just been taught wrong, I was 12/13 when I loand a pony I had to help brake her in and belive me, She was a hard one.She had mayjer bronks and landed on top of me twice.The owner of the pony taught to pony to jump from being 2 years old(not riding) and then when I got her I didnt realy like jumping, but she got me doing it with her.Im not jumping lolly with me on her so don't worry just small like 1 foot jumps, sometimes smaller I just want to get to sued to as much as possible!Also I took her for a walk today with my sister, a stallion cam runnig up to a fence when we were on the road.Shes in heat and she went burzurz and so did he I had to be really firm and the whole road of traffic came to a complete standstill,can you prevent things like that happening with stallions?
Unfortunately the only way you can really prevent that from a stallion is to not bring a mare in heat near them. Some very impeccably trained stallions are better, but even they can have an occasional outburst. I wouldn't bring her there again until you know she definitely is no longer "in season."
I would also be careful jumping her even with you not on her....if you are trying to make her sweat and build herself up a good LONG trot on a lungeline can do wonders. I've been doing that with Cinny...half an hour straight trotting and believe me, when I'm done he is wet from nose to tail with sweat. He is also starting to build some nice balance and muscles. I probably won't start him with even a pole on the ground until next summer at the earliest. He sort of gets overly excited at times and forgets his training ha ha.
