I know she's not confused because at first she stood well, especially for leg ups, but she has started walking away. I'm not slamming her back. Today she was the worst for a leg-up that she's ever been, it took a little while just to get her to stop backing up and swinging her butt away from me. When she finally stood and I got a leg up, she started walking off when I was still getting on.
I cannot corner her because there is electric wire on 3 sides of the arena.
