Total Hydration Drink for Dogs! K9 Power GO DOG,™, our hydration nutritional supplement for active dogs, is more than just water and carbs. AND it’s not a human sports drink reconfigured for dogs. It’s designed specifically for a dog’s metabolism and features a proprietary blend of electrolytes, short-burst and long-range energy fuels, plus vital buffering agents. These buffers help neutralize performance-robbing metabolic acid (H+) buildup.
