Her feet had been done just prior to her coming here, so we didn't need to do her for a couple of months. When she was trimmed, she was very good for the front, but started to lay on the farrier when he picked up the back foot and as he persisted, she would start to sink to her haunches. She was very hot in heat and her hind feet were pretty good, so we let her be. We tried again on Tues. and she did the same thing and not in heat this time.
A little background on her. She is very sensitive and can be explosive if pushed. Her handling has been minimal, but she is agreeable for the most part. She is not fighting, kicking or being agitated. She simply sinks to her haunches. Normally a rasp to the gut would probably be enough to get her up where she belongs, but her tendency to explode when nervous makes this seem like a bad idea. This family of horses do not twitch well, it makes the worse, so that isn't an answer.
Anyone have any ideas?
