^^^^ I'm sorry Sorrel but great mental picture there! I think we've all had the "come to jesus" moments at some point or another and I would again agree with everyone that this is what this pony needs. Big or small they NEED to respect your space. It's an animal that could kill you IF they wanted too.
I literally broke a bucket over a horses head yesterday and I'm not ashamed at all. A big 16H walker who is a disaster and food agressive. He is a boarders horse and she does not enforce him, but I do it's for my safety. Was sweeping out his stall he literally pulled the fork out of my hands and ran me into the hay feeder. Grabbed his grain bucket tried to back him off, gave him chances and he wasn't having it. SO I bashed him with it then continued to chase him away with just the handle. May seem outlandish, but it's not. You're either hurt or you show them you mean business.
