You train a horse with pressure. Not pain. Pressure. A horse doesn’t want to get in the trailer? You don’t force him. You just run him in circles, round and round the trailer until he’s breathing hard. Then you try to take him up the ramp again. He doesn’t want to go? You keep running him. Eventually, he’ll figure out that the pressure lets up when he’s in the trailer. He gets to rest in the trailer. So he’ll climb that ramp eagerly every time.
