The WaterBall allows your puppy to drink safely and efficiently from any premium water bottle such as Fiji, SmartWater, Waiakea and any brand that has a full height cap. The WaterBall much like hamster or rabbit watering station has a ball that slows the flow to a trickle but as soon as they lick the ball it releases a heavier flow. This gives your dog a steady drink while preventing choking or wasting water. The WaterBall is made from PTEG plastic which is the same plastic water bottles are made from and completely food safe. As with all our products the WaterBall is made in America and Warrantied for Life!!!
