I show the performance classes with my horse. Last year was his first year showing and before I bought him he hadn't been messed with much.It had been a few years since I showed previously, so I didn't have high expectations for either of us starting out last year. I have put lots of time into training him and teaching him to have respectful behavior. He is extremely intelligent and learns quickly which I considered a plus. However that has become a problem in the showring. At home, at the trainer I take lessons with ocassionally, even around shows now that he is used to going whether outside the ring or in the warmup rings he will do just about anything I ask of him. He is young(4 years) and while energetic is not hot, has mellow attitude and when asked to focus and work he gets down to business and even my trainer has commented several times that he has a good mind. However as soon as we step foot inside the show ring he becomes a totally different horse. He becomes hot and spooky. If he was a halter horse that look at me and ramped up attitude I believe is considered desirable however as a performance horse it is not. I believe it may have come about from when we first started last year. He was not used to it and was understanably upset about going to shows. He has since gotton used to going but figured out that gee, he won't get corrected in the ring and if I just refuse becuase things in the ring are just so scary(and get DQed) I can leave without doing anything. To watch him you would never know he had done these things calmly hundreds of times before and as I mentioned not just at home. It is fustrating as I know he can do these things and he becomes a uncooperative brainless spooky twit. He does this in halter obstacle, jumping, liberty(although in this class I don't mind) the only class he doesn't do this in is driving. What are some permissable ways to correct him in the showring? I know it is kinda frowned upon to correct in the ring and I can't really get after him like I would at home to school him but surely there is something I can do to correct him and teach him that yes he must do these things in the showring as well. I feel he is taking advantage of me and the fact he only has three tries and hes out and doesn't get asked until he does it like he would elsewhere.
