Has anyone else had the problem with their little stallion yelling at shows, he whinnys really loud as soon as I walk into the waiting area with him. I have worked him at home a lot, tying up the fillies and making him stand next to them without moving. He doesn't yell then, but as soon as I get into the arena or the waiting area, he starts up. I've tried the Vicks in the nostrils, treats, etc. I think he is looking for our other horses, or maybe he is nervous, don't know! Help, any ideas?
