I have tried that too, but, his attention goes away after a few time of doing it. I bought the pressure point halter and did the exerscizes.
I know what I need to do, get him to respect me IN the round pen. If he won't respect me in there, he won't respect me anywhere else either, and I prefer a smaller place to work, so if something happens, he can't go far.
Thank you for all of your advice. I have to change myself first, in order to change the horse. I will work him in the round pen today. I say 'work' but he is not just running in circles. We are communicating to each other. I just have to show I am more stubborn than he is. Which is hard, we are both stubborn, and neither one of us has patience. XD
