Gracie has chewed on a couple of dinningroom chairs, the wall in one doorway, and every pencil she can get ahold of, and socks. Otherwise she hasnt been to bad. OH, and she chewed on a pillar going into the home theater. That one really upset my husband since he's put so much time into it. Princess chewed a hole in the sofa out of boredom and anger (before we got Gracie), tore the stuffing out of pillows. And they both will chew any plastic container they can find. They have never chewed on shoes so we are lucky there.
