K&H Cool Beds III in BlueCooling dog beds help keep your pet cool even when it's hot. We've specially designed our bed with a cool core that diverts the liquid throughout the bed for advanced cooling power. No electricity required, so there's no need to worry even more about that electricity bill coming each month. Cool Beds are very simple to use. All you do is fill water through the easy fill cap and your pet instantly has relief from the heat. It really is that quick and easy, and the comfort you'll see on your pet's face will be that quick and easy too! Cool Beds are made of non-toxic materials and the tough nylon exterior makes this bed perfect for both indoor and outdoor use. As an added bonus to an already cool product you can give your pet ultimate comfort and let him chill out in complete style! Pick him up some Cool Bed III fitted sheets (sold separately). They are the perfect addition to a new Cool Bed III.
