Aspen was still nervous and reactive, but not as bad as yesterday. She seemed like she was actually starting to think about what I was asking instead of just freaking out. She tested me during lunging (for the first time) by either trying to run off when I wanted her to stand still or by not going when I asked her to. We worked through that pretty well though. I was pleased with her right up until I went to lead her out of the barn and she shoved me out of the way as she bolted through the door.
My standard response to a bolting situation is to have the horse go through the door (gate, whatever) repeatedly until they do it calmly. We started working on that, but she became even more belligerent, half-rearing and kicking out her heels. If a horse has that much energy, I figure they need to run, so I lunged her until she started getting out of breath and then brought her back to the door and did the squeeze game until I could send her back and forth at a walk. Then we tried the door again a few times. She still wanted to charge forward, so we repeated the whole process again.
After that, she was more willing to walk through the door calmly. Then I sent her back and forth next to her pen (too muddy inside the pen!) so that she wouldn't be so anxious to get back to her pen next time. I don't want her to think she only gets worked in the barn! Then I tied her up for several hours.
