I want you to hang your halter and lead on your left elbow and don't try to hide it. When you enter the arena, circle way around until you are directly behind him but well out of kicking distance. Approach and make him move. Run a couple of steps but stay well back. That should get him moving. Stand where he was, then repeat with the circling. He'll get so he'll keep his butt away and want to face you. As you approach him, shoo him away as tho shooing chickens. Use as much energy as it takes to make him move even just a couple of steps. The more you move him away the more he will want to connect with you. People find this hard to believe but it's true. After you've moved him a few more times, stand still, slump your shoulders and extend your hand, fingers down and see if he'll touch your hand. If he does, back up a few steps and turn and walk away. There's a good chance he'll follow you. When he'll stay with you, show him the halter and let him check it out. Rub his shoulder and neck then slip the rope over his neck. And remove it. Do it half a dozen times. If you want, walk away and come back. When he's not concerned about the rope slip the halter on, do it up, undo it and remove it and walk away. If you have to go back to the big circle. If you don't rush this process and no shortcuts, he'll be easy to catch after that. Mix up what you do, bring him out and put him back and remove the halter. Bring him out, pick his hooves and put him back or groom him with each time out getting a little longer. Surprise him with a few treats after grooming.
