I took it off, discovering that the saddle, while clears the withers, is too tight and would restrict shoulder movement causing pinching. I walked over to the tack room, a good 12 feet away and put it up. I turned around, Warrior was loose. The halter was completely off his head. I approached him and he turned to me and struck out with both front legs.
I was scared and started backing up and he came at me again in the same manner.
Then he took off in the direction of the road. My neighboor stopped his truck and walked over to him. Warrior knew what he was supposed to do, and stood there, relaxing a foot, though his ears were pinned. He struck out at my neighboor trotted off back to the gate. Here, we got a halter on him and the neighboor (who is a strong male and horse savvy) held him and we assesed what could have set him off. He swears the gelding was just being a jerk.
I think it was something pain related. There were a few wasps randomly buzzing around, they could have stung him? I also noticed he had a slight limp.
Did I push him into acting that way? Or was it out of meanness?
