Abstract: A portable drinking system for canines in the shape of a water bottle. The hollow outer molded water bottle casing splits lengthwise down the middle along the hinges, and is held together by clasps when in a closed position. The back half has two roll stops to hold the back half stable on a flat surface so that the back half can be filled with water bottle. One or more bottle pinches located inside the molder water bottle casing can hold a reusable bottle in place. The reusable bottle can be filled with water in advance, and even frozen, to provide a refreshing supply of cool water when away from home. The portable drinking system for canines provides a practical means of providing dogs and other pets with replenishing water when out on walks, traveling, or otherwise on the go.
