The Aqua Buddy is an automatic waterer featuring a two quart capacity. This waterer utilizes an innovative float system that will control the flow of water into the bowl, preventing spilling while maintaining a constant level of fresh drinking water. Simply attach any standard garden hose to the nozzle on the side of the Aqua Buddy. As the water level rises, the float is activated and automatically turns off the water flow when the dish is full. You'll no longer need to worry about constantly filling your dog's water bowl or cleaning up unnecessary spills. Bowl Capacity - 2 Quarts. Designed to lay on any flat surface (no mounting hardware). Ideal for garages, kennels or outdoor feeding areas, not recommended for indoor use. Works with any standard garden hose. Durable, sun resistant polypropylene construction. Veterinarian approved.
