I guess I should post the most recent event that happened yesterday.
Went to put out Amanda's horse in a small turnout yesterday morning. As I said before, I try to act big with him, so he usually behaves with me. Unfortunately the weather was cool, and the other horses were frisky, and galloping back and forth in a nearby pasture. I was trying to remove his halter when they ran by, and he started to prance. I put it back on to give him a "pay attention!" shake, but he could have cared less. Said 17 hand horse proceeded to push me into the electric fence, and nothing I could do stopped him, as he continued to prance, rear, buck, etc. I was like a fly on the wall to him. It went against my very nature to do it, but I just unsnapped the lead rope and let him go inside the (very small) turnout. He took off at a gallop. I did NOT want to get squashed by someone else's horse, or electrocuted by the fence (which is VERY hot).
Went to help get him in later that afternoon (because the woman that took the other horses in is scared to death of him). I let my boyfriend get Amanda's horse, as I had forgotten my boots. My boyfriend has experience with horses, and went in the turnout with the leadrope. Amanda's horse galloped towards him. I thought he'd pull a sliding stop, but nope! My boyfriend acted big, shook his hands and the leadrope in front of him, but that didn't accomplish anything. If my boyfriend hadn't jumped out of the way (and almost into the electric fence himself), he would have been charged over. The horse seemed to think it was great fun.
Needless to say, I too have finally given up handling this horse. I told the BO that I wasn't comfortable handling him anymore, even though I am. But honestly, why risk my safety with a poorly trained horse that isn't mine? If I get hurt, it's myself and my horses that will suffer. I figure this might be a wake-up call to Amanda that her horse needs a lot more ground training. The BO was a bit put-out that I refused to handle him, and said she'd "do it herself" and take a whip with her. I feel guilty letting this old woman try to handle him, but I honestly cannot afford to get hurt. I'm a graduate student on a very limited income (and have no time to get any first, let alone second, jobs!), with very limited insurance. I feel like this horse may actually seriously hurt someone if nothing is done to teach him some ground manners. It is completely the BO's call on this one, but I know I'm not the only one that wishes this horse would leave.
So really, I understand why Amanda would fear this horse, but she needs to DO something about it. As it is, she's been denying that he has any problem whatsoever. She actually came that afternoon (one of her rare visits) before we brought horses in. The BO told her what had happened that morning, and Amanda began to get angry and blame it on her horse's halter, that she stated was on too tight. In fact, it was set the same that it'd always been, which is a good fit (we just fasten the chin strap underneath the jaw, and leave the top alone). It just made me angry that she refused to see the danger of her horse's behavior, and instead tried to blame it on the equipment.
