my dogs skull isnt nearly as tough. I was eating some pasta in a chair, and my dog was sitting waiting for a scrap, but gave up because he knew he couldnt. But when i went to get out of the chair, i went to put the plate over his head. When i went to do this, he jumped up and clunked the back of his head off the plate, then kinda walked in a circle shaking his head, and fell over. He got up a few seconds after, but it was just funny to watch walk in a circle then fall over.
