The core of the Critter Cooler Dog Water Dispenser is the base unit. The front part is the water bowl and the rear holds the container. Designed by an engineer who builds extension bridges, it is strong and light. You need to be a bit of a geek to appreciate the design of the base unit but it takes about 1200 PSI for your dog to puncture the bowl. We have had some goats chew on it but it generally survives most animals.
