Exactly. Some horses will pin their ears when you do more intense things out of concentration. My horse will pin his ears when I do the "cutting" game or when I do quick turns because he feels the Drive come out in him. He's a very dominant horse. It's been my challenge to be able to work up to doing the more intesne things with him and have him still remain respectful. How you can tell the difference between "concentrating" ears and "mad" ears is if the horse is swishing his tail, he doesn't have much Draw to the human, he acts lazy-ish, looks disintersted and/or disengaged from the human, the human is working harder than the horse.....all those kinds of things.
