As I was thinking about this I realized that I was asking her to back "quite a bit" (just a few steps, 5 or so, but I try to do all things in moderation with her since she gets overwhelmed easily) and maybe she was just getting overwhelmed and "stuck"as someone put it.
Then if she starts any funny business I'll just ask her to go sideways, halt and then take one more step back and repeat for a few times then take a 10 minute break and come back to it, if she responded well the first time.
I'm going out there tomorrow so hopefully this will be successful. I'll let you know. =)
Isn't this the way with horses though? You think you're getting into something not too big but it's totally not what it appears. Gotta love that.
