I had a pony like that too. Fabulous at home, PC rallies and cross country but at a show she would be eliminated at the first jump! I know my mother was convinced it was me .so frustrating
My black gelding wouldnt jump a stick at a show. Didnt nap or do anything, just was too busy looking around he wouldnt go over any fences. no matter how much we took him out he didnt get any better! bloody horses lol
