Eco-friendly stainless steel water bottles for dogs made out of high quality food grade stainless steel with a 750ml capacity. They are bpa free and reusable and the healthier choice compared to disposable plastic products. The doggie cap allows your dog to lick the water slowly direct from the bottle. Caps are interchangeable and can be used with all our 750ml stainless steel water bottles by Green Bottle. A fine choice!
