I have a 5yr old Morgan that I bought about a year ago. I am the only boarder where I keep him, so very few people come and go but he's well-behaved and will happily go with whomever leads him to/from turnout (usually the BO or her husband, but my kids and friends of theirs have also).
However, if I am around and *leave* him with someone else, he loses it. He's fine if I leave him in his stall or turnout, but I cannot leave him in the cross ties or hand the leadrope to someone else and walk away.
I had a lesson today, afterward he was in the cross ties with his cooler on, so I asked my trainer to stay with him while I fetched my checkbook. She said the second I moved out his sight, he became extremely nervous, sweating, shaking and craning his neck in an attempt to see me despite the fact she was stroking him and trying to calm him down and the second I returned to his sight, he went back to chilling in the cross ties. This isn't the first time, my BO used to be my trainer, worked extensively with him and I, she feeds him and turns him out and I can't even leave him with her. He nearly flipped himself in the cross ties when the saddle fitter came out because I went to get some saddle pads from my car and both the BO and saddle fitter were right next to him, trying to calm him down.
I'm happy he obviously likes me but this is getting old. While I'd never leave him alone in cross ties, it's pretty ridiculous that I can't walk 20 feet away from him when someone else is standing right there. I've now had 2 trainers tell me they've never seen a horse do this before. So how do I get him over this?
