Help your big furry friend beat the heat with this self-cooling dog mat. It's a generous 40 by 28 inches, giving plenty of room for large breeds to stretch out. The magic is in the special Q-MAX fabric – it doesn't need water, ice, or electricity. Just lay it down, and as soon as your dog lays on it, the fabric pulls heat away from their body, creating a cool, comfortable spot. One side is the cool ice-silk fabric; flip it over for a soft, short-fleece side for cooler days. It's thicker than many mats for extra durability and support. When it's dirty, just toss it in the washing machine. It folds up easily for storage or to take in the car. Great for use in their crate, on the floor, sofa, or in the car during summer trips. Note: It ships compressed, so let it fluff up for a bit after opening!
