I've noticed Scooby scratching his left ear and then shaking his head. This makes his ears flop together loudly so he wakes me up a few times at night. -_- What could this be? I've checked his ears & there doesn't seem to be anything in there. There isn't a whole lot of hair, although I guess I could clean it up a bit to make sure but I'm afraid to hurt him if I do it the wrong way.Any suggestions??
