Details Ruffwear Swamp Cooler™ Dog Cooling Vest When there is little shade and the temperature is high, dogs can rely on the Swamp Cooler to help them get outside. Wetting the vest activates Ruffwear's Swamp Cooler™ Tech, using evaporative cooling to provide that refreshing, just-stepped-out-of-a-lake feeling. Simply soak it, apply it to your dog, and go. Re-soak it when it dries to recharge it. The Swamp Cooler Vest has side-release buckles for easy on/off and a lead portal for use with a harness.
