My mare is one of the "I'm trotting oh no I need to go bathroom let's slam on the brakes suddenly right about nowwww! Oh Mum, by the way are you alright? You almost went over my head just then" kind of horses
I tried to teach her to move her butt when riding, but she won't budge. It's literally the ONE thing she just will not relent on. I've tried several tactics, all have failed. At the walk I don't mind too much... but the other day when she did it at the trot, I almost came off.
