Cooper has really been a good boy! He has only chewed on a couple of things since we brought him home in September. He did chew up my brand new car charger for my camera last week but I DID leave it where he could get it. We never yell at him or strike him as we are sure he was not treated well before becoming a stray. He knows when he is bad just by the tone of our voice. We crate him only when we aren't home because he has such separation anxiety. I just laughed when I saw the mess this morning as the other dog and cat were just watching him go at it! It was an ugly pillow anyway!!!
