Off subject a bit; but this is what my son's boxer chewed on when I left the house for a couple of hours. I doggy day care her, with my two (a Shih Tzu and a Toy poodle) - they have access to the doggy door so can go outside. She's done this three times now; destroying the little ones' beds - not hers. She knew she'd been bad when I walked in as she ran straight for her crate and went in.
