I'm loving reading all these stories, some of them are straight up crazy!
I think my "craziest horse" story has more to do with humans and our silly emotions than the horse actually being insane. The story goes that he was originally owned and started by a member of a family I work for's ex-husband, the man was green as grass when it came to horses but they gave him this colt as a "project" ...
I believe the colt had, had 30 days but the guy spent about a year and a half chasing the horse around a round pen, and I honestly think it warped his mind. The man was not a nice man, and eventually after some horrible stuff happened, left this woman, and their kids, high and dry.
Then I walk into this situation, (lucky me) which was clearly more emotionally heated than I was willing to deal with, and was asked to ride the horse. Our first round-pen style ride went well, he hadn't been ridden in a year, and seemed sweet and pretty well-natured. The second ride we planned to do a sort "outside roundpen" ride, really calm, nothing spectacular. It also was going well until we were walking up a nice, gradual slope type hill when he completely blew. I definitely did not see it coming, he went up, span in the air, I came off and he proceeded to run straight down a bank, into a barbed wire fence. (He literally ran straight into it, his nose had barbed wire cuts... I have never in my life seen cuts on a horses muzzle like that), he took down an entire fence line as he went, ran all the way home and we found him down by the river, shaking, and pretty cut up. No really bad injuries, but he had bloody cuts and scrapes all over. So we cleaned him up, calmed him down, went back to the arena with him, so that he didn't end on the worst note ever
, and he was fine. It was the strangest thing. It was almost like he needed the walls to protect him, but his destiny was suppose to be mountain horse..
I never wanted to get back on him after that, not because of his actions but because I felt the situation with this poor horse just too strained and awkward. I felt that some members of the family almost wanted him to be a nut job, whereas others wanted him to be a good, calm horse... both to prove points. They were definitely putting their own feelings about his original owner onto him, and it wasn't fair. There was no way I was risking my neck, and I had other horses to ride anyway that were doing much better, so he slipped out of my string and they eventually hauled him to a sale I believe.
That story taught me a lot about how people's emotions and personal feelings can really effect the mental state of a horse... and how it is treated by others. It was very sad.
