I'd do work with her on the ground and she yields away from pressure fine. Before, in the stable she would just swing away when I put pressure on, and if she'd swing towards me I'd slap her with the lead and she'd back off.
Yesterday though she was really bad. I had her tied in the walk in stall and she kept looking behind her and then started swinging her hind end towards me so I slapped her with the lead, but then she just stomped and swished and kept swinging into me, so I whacked her with it, which she promptly ignored and then I had to jump out of the way and pull her head around the avoid being squished between her and the wall. I took her out and did some ground work, trotted her around, backed her etc and she seemed fine but back in there she did it again, ignoring my whacking lead.
I know she was disrespecting me, and just because she is more interested in what is happening doesn't mean she can do that so obviously I want to stop this behaviour immediately.
I was thinking of getting a crop or dressage whip or something so if she walks into me I can use that while staying out of her kick range... would that work?
What are the best things to do?
Can anyone recommend some exercises?
