OMG, I know EXACTLY what you mean!!!
Look into the face of pure EVIL:
This is Beauseant, our 6 yr. Old OTTB whose report card Looks like this:
Plays well with others: F
The guy we bought him from had to turn him out with cows, because he kept fighting with the herd's alpha.....a HUGE, chunky paint STALLION!! Apparently Beau wouldn't accept his place in the herd and the fighting continued day by day.....our boy took a heck of a beating. Beau kept coming at the Stallion, challenging him....he refused to back down, despite being horribly beaten. When we bought him he had at least 30 severe bites in various stages of healing....most on his neck and some so exensive I didn't think the hair would regrow. I was brushing flaking scabs off of him for six weeks after we bought him.
Finally, fearing for his life, the guy put him in with cows.
After we bought him, he was moved into a herd of 8 mares and geldings. Before the month was out he was supreme ruler and dictator of the herd. When we would go to get him in the field,, we never had problems with any of the other horses crowding us or even coming near us....NO ONE approached him....or anyone near him. When we put him back out with the herd after riding, he would herd the herd.....around and around the pasture he would herd them, with the expertise of a boarder collie.
At his second farm, the BO thought that HER OTTB could teach my OTTB a lesson, and put a stop to his bullying. I warned her of Beau's past record of fighting. But she didn't listen, she acted like it was a game. So she threw our boy into a herd of four OTTB geldings.....I was frantic. He waltzed in there like a ballet dancer, running and rearing ....he picked up the heavy solid wood jump pole in his mouth and tossed it aside. Then he walked up to the alpha....and the alpha caved in. He followed Beau around like a puppy dog. A few days later The BO went into the arena to play ball with her horse and Beau. Beau was very interested in playing, but her horse refused to even approach her when beau was in the arena. He literally went and stood in a corner.
So, she later put him in with her young and wild OTTB....they seemed to be getting along, both were young OTTBs, and full of energy and roughhousing and the next minute there was a ruckus. No one saw what started it, but the hooves were flying. Her horse ended up with a nasty laceration across his cannon bone. And she said "that THING" ( Beau) was never allowed anywhere near any of her horses ever again.
Now we keep our horses at a private farm and he and Epona are the only two horses on the property.....and he bullies her somethng fierce. She's got quite a few bites on her, minor ones....but still......he chases her and bites her waaaay more than we like. Luckily, we do have the option to put them in seperate pastures if the need arises.....
He chases the chickens out of his field, tries to squash the property owner's dogs, and just last week threw a terrible fit when 6 deer wandered into HIS pasture.....he chased them off......all fire and brimstone. Putting on quite a show, rearing, bucking and kicking.....
With humans. However....he is a total love bug.
