Give it that stiff upper lip. Don't make faces. Pretend like it isn't happening. Try to go smoothly forward and carry on. Don't circle to repeat. That is an error. Try to quickly get the horse under control and move into the next movement. It probably doesn't look as bad as it feels. If the horse flips a lead, always correct it or you will get a low score on the subsequent movement. If the judge thinks that the situation is dangerous like rearing, he will ring the bell immediately for elimination. If here is more than 20 seconds of resistance, that also is elimination. Otherwise just try to ride through it. Problems usually work themselves out after a movement or two. Good luck!
