When a horse 'barges', it means he keeps pushing you out of the way.
Horses often barge when they are impatient either to be let out, fed, or to get to other horses.
Barging becomes a real problem when it turns into a habit. Some horses develop the dangerous habit of barging past their handlers as soon as the stall door or paddock gate is opened. This sort of behavior shows a lack of discipline and disrespect for the handler. If you don't take control - you could get hurt. What you can do.
