So I have an 11 yr old 16.1 hh thoroughbred gelding called Salty who raced until he was 7. He is the most amazing horse he will do anything you want him to do and has a kind nature. But he has a problem which really scares me sometimes, he will be going amazing and then all of a sudden he will snap and start bucking and rearing and doing everything imaginable, it happens about once or twice a month, I don't know if I am safe riding this horse as when he will snap is unpredictable and when he does it puts me in danger, last time it happened I broke my finger.
Please, I am really lost as to what is wrong with him and what I am supposed to do about it. I spoke to the old owner of him and she said it always happened to her too (it would have been nice if she had told me this before I bought him) and she sent him to some of the best trainers and they all gave him back to her saying that they couldnt do anything for that horse and that he could kill someone, one of them even suggested putting him down as he is unsafe.
