Would like to hear of how others may have addressed this issue. I have a horse who has done a little competing with his previous owner, not a lot, but he has had some competition exposure. I took him to his first competition recently and discovered he is frightened of horses coming towards him, and generally couldn't deal with the atmosphere. All the evasions came out, rearing, spinning, bucking, refusing to move. Fortunately I was able to warm up away from others but that won't always be the case. I think before I compete again I will try and expose him to as many 'different' environments as possible so he gets used to seeing different things. He does go to club rallies but of course that doesn't have the atmosphere of a competition.
