The KONG Aqua, formerly the Cool KONG, is a floating retrieval toy that promotes fun and exercise both in and out of water. The KONG Aqua has a foam core that keeps it floating while your dog swims out to fetch it.Splashing in the water with your dog is the perfect way to pass a summer day. The puncture-resistant rubber is good for your dogs teeth and gums. The sturdy nylon rope is attached for throwing or playing tug-of-war. KONG Aqua is also great for retriever training. When you use it on dry land the unpredictable bounces develop your dogs reflexes.
