A perfect gift for any dog owner. * This "green friendly" BPA-free, stainless steel water bottle features a flow-controlling roller-ball dispenser to release water when your dog licks it. It has two openings: the small one on top controls the water flow when you hold the bottle upside down for your pet to drink. The second opening has a wide mouth to allow for filling and cleaning. And when you un-screw the whole top of the bottle and flip it over - it"s a cup for a longer drink! 10 ½" high and holds 24 oz. You can hook the bottle to your belt with the handy carabiner and the bottle fits in most cup holders.
