Cool Bed III keeps pets cool and comfortable. Does not require any electricity. It's designed to radiate heat back into the air or the floor surface to keep pets cool. The water-saturated Cool Core™ inside the Cool Bed diverts the liquid better than ever. The Cool Bed III absorbs your dog's natural body temperature of 102° Fahrenheit and coverts it to room temperature, which is normally well below your dog's body temperature. The Cool bed III is the choice for any dog owner looking to offer their pet a comfy, dry, cool place to relax. Recommended for indoor and outdoor use.
