I don't tolerate pinned ears or turning their butt towards me at all. If he turned hisbut towards me, he'd get a nice stripe with a lead rope. And when my horses pin their ears at me while I'm tacking up and give me a dirty look, they get a quick slap on the neck and a "no!" just with my hand. They learn, they are like children, one little quirk leads to another..
~Started young horses in Bosca te Ador, unto the two rein the old Spanish spade, brought them along with two hands that were gentle. Some fine reining horses as ever were made~
