Keep your canine companion cool with Coleman Cooling Dog Mat! This cooling mat is stuffed with a self-cooling gel that does not require electricity or refrigeration. It is activated by your furry friend's weight and heat and reduces the temperature by about five to ten degrees. With up to three hours of coolness, this pad is paw-fect for indoor or outdoor use. It will recharge itself after 15 to 20 minutes of inactivity. It easily folds as well, so you can put it away during colder months or take it with you on the go.
