At the barn I ride at, the outdoor arena has always been Rainy's nemesis. Now it's been enlarged and it's even worse. Before, she would be a bit spooky and start backing up really really fast plus bucking during cantering, but now that it's bigger, she's bucking no matter what were doing, breaking gait constantly, and now, rearing and throwing me of. I know she's not afraid of wind and birds and trees, because I've ridden her on trails and she's fine with it out there. But in the arena, she's a mess! At first I thought it was because she was riding alone, but now she's doing it when there are others riding with her too. The outdoor arena is connected to her pasture, and I'm starting to wonder if this has anything to do with it. Whenever she's thrown her little hissy fits there are all her mare pasture mates are out there, so is there anything I can do to make her knock it off? Taking the mares out is not an option, so is there something other than that that might work? =[ Thanks.
