Molly Mutt's Dog Bed Duvet is meant to be stuffed with old clothes or linens for simple, home-made comfort, or it can be used to cover an existing bed. The zippered, all-cotton duvet is gusseted and comes in small, medium and large sizes. One reviewer with an incontinent Labrador chose the latter for an added layer of protection. The preshrunk fabric retained its shape and colorfastness after multiple rounds in a washing machine and gas dryer. Modern styles such as Mr. Roboto, Bird on a Wire and Beast of Burden give dog owners nearly two dozen striking designs to choose from.
