Abstract: A fitted dog bed sheet, providing adjustable sizing to fit any size and shape dog bed. Using drawcord and cord locks, users may tighten or relax the drawcord to the desired fitted size. Using this type of locking system with the lightweight fabric allows for a smooth, easily compacted bed-protective design, and the protective flap function protects the drawcord and cord locks. The water-resistant, eco-friendly fabric option (e.g. PUL, Polyurethane Laminate), ensures the dog bed is protected from becoming soiled, similar to a waterproof mattress cover. Therefore, it decreases laundering time, costs, water use, and expense of replacing dog beds often. For pet shelters, our dog bed sheet provides a practical solution for a physically and emotionally comforting dog bed that minimizes shelter animal anxiety. For the consumer market it offers a valuable solution for extending the life of a dog bed, while providing a customized look and feel.
