When a small piece of Super Dog Chew is leftover,soak it in warm water for 5 minutes,then it can be placed in a microwave for 40 -60 seconds or until it puffs up and can be given back to your dog after it cools down for at least 2 minutes. If the piece is too small – and could pose a potential choking hazard to your dog – throw it out. Always supervise your dog while chewing smaller pieces and provide plenty of fresh water for them to drink.
