I do not agree at all with chasing him. If a horse does not want to be with you, like in this case, chasing him will serve no purpose other than to finally "give up". You don't want him to just give up and tolerate being caught..you want the horse to WANT to be caught, to WANT to be with you.
A good leader won't always work a horse...if you go up 5 times a week, spend one of those days just hanging out...and doing "undemanding" time.
That's the argument I always get, it gets really old. My mare didn't like to be caught for whatever reason, so I took a day and chased her. It made it MY idea, asserting MY dominance. She realized it was easier to just be with me than not be with me. She didn't "give up," she wasn't "beaten into submission," she made a choice to be with me. How is it any different than the Monty Roberts "Join up?" It's not, it's a great way to establish your role in the relationship, as well as gaining trust and respect.
I worked with a mare who wouldn't only run away, but KICKED when you tried to catch her. Keep in mind, this horse didn't work, she wasn't ridden, she was groomed. But she did NOT want to leave her buddies in the pasture. So yes, she dared to spin her ass at me and she got whacked so hard she'll never forget. And I chased her. And it worked.
That's just two stories. I have tons more. Have you any experience with this method? If you don't, how do you know it won't work, or that it doesn't help or accomplish anything? I never said other methods won't work, because I'm sure they do, but I guarantee they will take longer.
Horses need discipline, not just praise when they do something good, although the praise is very important, but there has to be a consequence for his actions. By sitting there and reading, you are not telling your horse it's bad to run away, just that it's good to be with you. Yes, it's good to be with you, but if he doesn't want your company, it's entirely possible he'll start running away again, because he doesn't know that that's the wrong thing to do. You are the boss, and he has to do what he's told, period. If a child doesn't do his chores, he gets punished. You don't wait until he does them and just praise.
