Automatic Refill Dog Water Bowl. Dang, that’s cool, Marge. Now if we can only find something that does the same thing for dog food, we’ll never have to see that mangy mutt again. $29.99.
This 1.8 gallon automatic stainless waterer attaches to any garden hose and provides consistent fresh water for your pet at all times. The bowl is fabricated from heavy duty hygienic stainless steel with a durable cover (removes for easier cleaning) made from high density polypropylene, which protects the mechanical float valve providing safety and reliability. Ideal for your cat, dog, sheep, goat, or other animal hydration needs. No training required.
Dogs often turn bowls over. So the valve can let the water flow all the time.
Its good because you never have to refill the bowl but since the bowl would be outside all the time you'd have to clean it out all the time.
