This contemporary dog bed USES NO ELECTRICITY because it reflects your dog's own body heat back to the animal. The plush fir pad cover is reversible and self-heating on both sides. The adorable dog print fir pad cover is completely machine washable. Designed for puppies, aging adult dogs, nurturing females as well as dogs recovering from illness, injury, surgery or bone and joint disease.
