• The cooling mat is made of 75 percent nylon, 25 percent polyester which makes it a self-cooling fabric. The cooling pad is fluffy soft with superior silky hand feel. The cooling mat is different from most pet cooling mats as it requires no water, electricity, or refrigeration. The dog cooling pad can absorb your pet's body heat while the mat feels cool on the surface. The cooling mat can be machine or hand washed, machine was on gentle cycle and tumble dry. The cooling mat for dogs is durable and will not deform after multiple cleaning.
