The outdoor water dish that stays full! Simply attach the 3/4 inch hose (included) to your garden hose, turn on the tap, and the bowl fills to the perfect drinking level. The automatic float controls the water level so there is no spilling or overflow. The bowl is automatically replenished every time your dog drinks, so the water always stays fresh. Made of chew-proof, rust-resistant galvanized steel for years of service. Comes fully assembled. Holds 13 quarts (3.25 gallons).
