Here is the issue: trailering. Ever since the day he was born, he has been a pain about it. No, he doesn't rear up, bolt away, run side to side, put anyone in danger... But it takes half an hour to get him into a trailer. I can reserve time to get there early, but I don't like standing in the trailer with him frozen and heels dug in. He doesn't show much of fear, just that he doesn't want to get it. When trailering, he is still and quiet, he doesn't sweat or show signs of stress in the trailer, and he'll eat in there. He hasn't had any accidents previously, and has never had a harsh hand forcing him in.
What have we tried?: Eleven trainers that "could certainly fix the problem", a bum rope, a lounge whip (not lashing, but waving behind him and bumping his tail), a stud chain (for extra pressure) and yes, natural horsemanship. Three PNH trainers (highly successful) couldn't improve him. Yes, and a clinton anderson trainer... Then me attempting Monty Roberts methods... He listens great with that, getting in, then backing out and praising, but then when it comes time to get him back in, it takes twice as long.
What can we do?: Give me advice! We are joining the high school equestrian team, 4-h and have a lot of shows coming up, no time for lollying around with trailers!! So whatever you can spitball, I will try ASAP.
Thank you so much if you can help!!
