If she doesn't know how to lunge and even if she does, you can work her in the round pen (if you have one) and if not then in the arena and free lunge (without the rope) and drive her forward. That alone will gain some respect....there's different things you can do when free lunging to gain respect, not just driving them forward. Like the other day I went out and turned Thunder loose in the arena to stretch his legs and he would NOT let me catch him. He's only ever done that twice. So I would come close, he would take off, so I would drive him forward and each time I attempted to ask him to whoa then ask him to come to me, If he didn't drove him forward again. Then he started licking an chewing and he came to me and I was able to halter him and cool him down. Just an example of gaining the respect back. Good luck!
