Working canines experience heat stress more quickly and severely than humans. The Canine Body Cooling Vest safely increases work tolerance time and reduces the negative effects associated with heat stress. Keep your partner vigilant and alert with the Canine Body Cooling Vest. The “optimum cooling temperature” inside the cool vest (approx. 55° F/13° C) absorbs excess heat from the canine’s ventral abdomen allowing the canine to naturally cool itself, reducing its respiratory burden.
