All Terrain Dog Dry Comfort Pet Beds are designed to be more durable & versatile than the average Pet Bed. The sturdy indoor/outdoor pet bedding features a heavy duty, hard wearing, nylon cover which is coated with PVC to make it more durable and waterproof. The outer walls of the bed are extremely sturdy though still comfy so wont loose their shape. The inside sherpa cushion is reversible and has a removable cover for easy washing. These beds not only look good but your dog will love the comfort in either Winter or Summer.
