My boy is a black skinny. Have looked in his ears and nothing conclusive. He shakes his head violently which causes his ears to flap around and makes a fluttering sound? He is not scratching his ears that often. As I’ve mentioned he is black. Did look at his ears with a powerful flashlight and everything looked good.So my question for the forum is this: Is this a character trait of skinnies? Thanks to all that respond.
