Select Companion Pet Cooling Mat (Medium) - 20" X 16"

I ordered this thinking it was for a medium sized dog. I have a Shih Tzu and it's too small. The mat does have a nice cool feel to it, but more suited for a puppy or cat. If your dog likes to spread out when sleeping I would get the large size.

I bought the size medium of this pet bed for my two cats. They are long haired, and kept inside. Since my AC is turned up during the day while I'm gone, I thought they may enjoy a cooler place to nap. So far they aren't crazy about the material or the smell of the pad. It does feel slightly cool to the touch, and is obviously made of high quality material - it's very heavy. If my cats ever decide to love it, the medium size will be plenty big for them both. The picture I took includes a standard size pack of markers for size comparison.
