PupCup

The Original PupCup is the dog bowl that lives on the bottom of your water bottle so you always have a simple and convenient way to give your hound clean, fresh drinking water without contaminating your own. It fits on 32oz Nalgene, Hydroflask, Kleen Kanteen, Coleman, Thermos, and many others including most of the disposable bottles you buy at the convenience store. If you have water, your hound has water.
