I agree with the suggestion that when you catch him you should just give him a treat and love on him for a while, than let him go. That way he will stop thinking that you are going to pull burs out of his ears every time he lets you catch him! Also, do you have a small pen (about 60' in diameter)? It sounds like this horse would be a great candidate for round pen training. When I started mustangs under saddle in WY we always used the round pen to gain their trust and teach them to be caught, as well as to accept the saddle and rider for the first time. Ken McNabb sells a great DVD called Round Pen Basics, most of the other "natural horsemen" out there have videos on it as well. (

I would also teach him to put his head down on cue so you can get him to lower it back within your reach when he does throw it up in the air. Put gentle downward pressure on the lead rope and hold it until your horse puts his head down, even a fraction of an inch. As soon as he does, release the rope and reward him. Practice this again and again until he will put his head all the way to the ground for you. If he throws his head up against the pressure at first, just hold steady, neither increasing or decreasing the pressure, until he brings his head back down. For more horse training info, check out
