Meet Big Shrimpy's Original, the bed that is built to last. We back that up with a 3-year limited warranty. The durable outer cover has a 420 denier packcloth base and a comfortable faux suede or soft fleece sleeping surface. The inner liner is a ripstop nylon that is odor and liquid resistant. Machine washable and dryable, and with component parts available separately, this should be the last dog bed you'll ever need to buy.
