The automatic dog waterers have optional thermal covers, sold separately. The "Chiller Cover" is a 3/16 inch laminated, metalized bubble cover that reflects the sun's rays, helping keep the water container cool. Try this when it gets hot. Freeze a gallon jug of water and drop it into your critter cooler like a big ice cube, close and then cover with the chiller cover and the water in the bowl stays cool all day.
- Thermal sun protection helps keep water cool, healthy and dogs happy
- Dogs prefer to drink cool water so will drink more and are better hydrated
- Cool water inhibits algae and bacteria growth, better for dog health
Not recommended for "chewers" unless you also get a Heavy Duty Cover to cover the Chiller Cover. The Heavy Duty Cover is tear resistant.
