Thank you for your inquiry to Drs. Foster and Smith. Unfortunately, there is no such that as a tear or chew proof bed. We do have the Dura-Ruff bed Small 36" x 21", 9N-34491. Tear-resistant 600 denier nylon is much more durable than cotton which is the strongest cover we have. You may want to try a softer cover on the bed such as the Angled Luxe Dog Bed 21" x 36", 9N-83342. This cover has a little more stretch then some of the others. However, the determined pet may rip and shred any bed.
