First of all you want to ask a trainer for there advice or find a place near you that has some one who knows how to train a horse that miss behaves. I am at a barn that the owner trains horses for a living and she does a whole bunch of stuff too. But she uses the Clinton Anderson methods and she is an amazing trainer. She is helping me train a horse his name is Oliver and he is getting along very nicely. So I would recommend finding someone who knows what there doing.
Good golly ollie
