I have always boarded my mini at "big" horse barns. When teaching him to cross tie, I found it was almost impossible using standard height cross ties. He could swing his butt underneath them and turn himself completely around, sometimes more than once. Then he'd stand there with this big mess of ties twisted around his nose. Either that, or he would rear up. I found a simple fix (which probably is a "DUH" moment for those who only have minis, but took a while to come to a newbie mini owner):lower the crossties to mini height! He can't twist under them and he can't rear. His forward and back motion is much restricted, so the only thing left for him to do is....STAND! I also always use the word "stand" when I want him to remain motionless. To me, "whoa" means stop, but be ready to do something else. "Stand" means stay here.
