The Green Pet Shop Cool Pet Pad is a revolutionary new self-cooling pet cushion that works without refrigeration, water, or electricity. It cools your dog as soon as they lay on the pad. The cooling pad is weight or pressure activated, so as soon as your pet lies down, the cooling effect starts and it lasts for hours (depending upon conditions). Every area that their body comes into contact with will be cooled because the pad absorbs your dog's body heat to cool him or her down. You can get a larger bed for a smaller dog if they move around a lot. It's also incredibly convenient; it folds easily, wipes clean and has sturdy construction. Place it on the floor, on the bed, in the car, or even outside. Your pet will stay so cool; you may decide to get one for yourself.
