Waterproof dog beds are designed with a moisture-resistant layer to prevent the inner filling from getting soiled. While slobber and accidents may create a mess, waterproofing keeps that mess from soaking into the filling fibers. The waterproof layer is typically machine washable and helps keep the fluffy filling hygienic. Removable covers are the easiest to care for. Filling varies depending on the model selected, but memory foam is the most durable option. Beds are usually available in small, medium, and large sizes, but don’t rely on company size charts when making your selection. Look closely at bed measurements to get an accurate idea of the size. Make sure to pick the right size for your dog so they can spread out, curl up, and sleep comfortably.
