A friend rescued him and brought him to the ranch where I work. He will be turning 5 soon. While he allows people to brush him and whatnot, he doesn't seem to have any idea what it's like to be a horse. Even being groomed makes him really excited. (He lifts up one of his front legs when he's happy, a habit.) He should be able to be lightly ridden by Summer, but what's more important to me is getting him to like me and like being around me.
He is mistrustful of humans. While they can approach him, he is rebellious often and hates having humans control him, probably a result of the harsh treatment when he was young.
He is a beautiful, sweet horse and I really love him. I just don't know what to do. Are there any exercises I can do to bond with him?
