This is one of the most dangerous job's I can go to, as one well placed kick can change my life in a bad way temporarily or permanently. This horse came to his new owners with this problem. Personally I would have passed on him when I was told "Don't try to lunge him, he rears" but that's just me, too many good horses out there. I will not reply to negative comments by children. If you are an adult, own a horse, and can type without expletives or wishing I get killed, I will respond. Horse training is dangerous, don't try this at home. Thanks for watching. This horse was not really an aggressive horse he was dangerous because he had been made to fight to defend himself.
