What do you do to make her quit?
I grabbed her halter, a lead line and my short whip, and we worked on personal space. And when she invaded mine I nailed her for it hard.
She's funny... she really does have an attitude, but it's easily broken through. As soon as she had the halter on she was really pretty good. I think we'll take the short bat with us when working in the paddock around her for awhile again so we're ready if she pushes it again when she's loose.
