Travel Pal is the dog watering system that is rugged enough for outdoor use or travel, but attractive enough for indoor use. The transparent polyethylene jug allows you to monitor the water level. The jug is cradled in a chew- and impact-resistant black plastic base that doubles as the water bowl. Advanced screw-on cap design features an O-ring in a machined radial groove, which creates a vacuum to maintain a constant water level in the bowl. The molded handle makes it easy to carry. Measures 13 inch long by 18.25 inch wide by 14.75 inch high, holds 3 gallons.
