My 5 year old APHA stallion is horribly social! He is well mannered as far as general behavior and safety around other horses and people goes, but he will not shut up at the shows when I have him in hand or at the trailer. He is very loud calling to any other horse at the grounds who might have called out, and it never fails that my ear is right there when he does it. When he calls, it is not stallion related, it is just like the call of any other horse - he is just much more social. He has gotten pretty good about not calling when I am in saddle at the shows, but I took him to a trail ride with out his buddy gelding, and he called to every horse he saw in front of him for four hours. I repremand him by making him back or turn circles when he calls out (he is lazy, so I try to increase work as a punishment), but he often just anticipates his punishments and begins backing or speeding up as he calls because he knows it is coming anyway.
He is improving with experience, but I was just wondering if there are any other ways to work with this so that I don't loose my hearing :)
