The stallion I had in high school was the most 'mouthy' horse I ever had. Stallions in general tend to bite more than other horses... and with him, I had to be even more rigid because he was always thinkin' of doin' stallion things. But he was an easy stallion as they go. I'd like to think I had something to do with that.
A horse in the round pen the other day. I tied mine up on the outside. I looked back as I walked off. The horse had his head thru the fence trying to bite mine and mine kicking , trying to get away. I looked under and Oh xxxx! I tied him up right by a stallion. He thought he wanted a piece of me too.
