"I never have had the pleasure of taking a lesson from Chris. I know that the horse I used to lease behaved like a gentleman during lessons but when I was alone with him, he tried to make me fall off because he got away with that with his owner who was a woman. I decided to give him ground work and that helped some. The thing that helped the most was letting him know I wouldn't put up with that. I was the only person in the barn that could ride him except the instructor. Then I bought my horse and she was forced to ride her own horse. He ran that woman into every wall he could and when he came to the gate to go out to his stall he parked his feet and wouldn't move. She tug and whipped and he stood his ground and she said "well aren't you going to help me or what"? I said if you want me to sure. I walked up to the horse and said it was ok and to walk on and he went with me right to his stall. Go back to some groundwork and don't ride your horse until he shows you some signs of respect as you progress on the ground. Once you have his respect he won't constantly misbehave. It sounds like you have some fear of him, get to know your horse on the ground in a relaxed setting so you feel calm. When he feels your calmness and your authority he'll respect you and then begin to trust you."
