I will ask the trainer
Ok, I get what you guys are saying. Yea, she did tell me she mostly wants the horse to listen for his signals. She said everything she does is to train him for riding. I don't want to misrepresent her, because she could be doing things that I don't understand the higher meaning of.
I will ask her next time she works with him what body signals she is using. Another thing is that she had neck surgery and is still rehabbing her arm, so she has told me that it is awkward for her to do everything the way she normally would. But I will ask her to clarify her signals for me so I understand, and can make sure he understands. That's important.
