Ok....everyone keeps telling me I need to do 'ground work' with my horse. First off, I'm not sure exactly what that means. I know how to lunge line her in theory however every time we start she makes a half circle and then crosses the middle and walks up to me. She did beautiful circles for the trainer (who is currently out of town) and he used a whip cracking behind her to keep her moving but when I crack the whip - which has never touched her, she startles. I've only had her for 2 weeks and the whip has never even come close to making contact. ...I can't say if her previous owners did or not... but she didn't react at all when the trainer used it.
Any ideas or suggestions?
