One last rant/question about my horse. Yesterday he ripped the top off of my rabbit cage. I went out and tried to get the rabbit before it got away and to try to stop him from doing any more damage. I led him away, he came back. I whipped him with the lead rope, he didn't care. I waved a 2x4 at him, he came towards it. He had issues with being tied, and if I put him in the pasture alone he freaks out that's why I didn't do any if those things. I brought the whip into the pasture the other day to try to get him to stay away from me while I put fences around the trees he was eating. The other horse ran at the sight of it, he tried to chew on it. I even swished it back and forth behind me when I walked and he was still so close that he was getting hit I'm the face. I have had people (like my ferrier) comment on how desnsitized he is. Seems to be that the only thing he is afraid of is a good electric shock. Is it possible for a horse to be TOO desensitized? Or maybe he's just a little slow mentally?
