One of the reasons we purchased this bed was because we’ve had trouble finding a comfy bed that is both durable and easy to wash. Our 11 month old labradoodle (who has been a very stubborn potty trainer) had an accident on the bed about a week after we got it. I pulled the cover right off and threw it into the wash. The middle plastic cover proved to be entirely water proof as there was absolutely no seepage. Would buy this again (and at some point will probably buy another cover just to have some more color option). And our labradoodle hasn’t even attempted to mouth the corners as she has with all other dog beds. Very pleased with purchase!
