Let The Big Dogs Drink! The Drinkwell Big-Dog Fountain uses the same innovative watering system as the Original Pet Fountain.
Featuring the patented free-falling stream of water that consumers have come to rely on for cats and small dogs for the past decade. A large charcoal filter removes bad tastes and odors leaving your pet with fresh tasting, filtered water.
Designed by a veterinarian specifically for large dogs, this pet fountain holds well over two gallons of water. Research shows that one of the best ways to improve your pet's health is to get them to drink more water. And the best way to do that is by using a free-falling stream of water continually aerating your pet's water with healthful oxygen.
