Abstract: A portable drink dispenser, particularly suited for watering animals while traveling, is disclosed. The dispenser includes a flexible bottle-like container for holding the liquid, such as water. The container includes an upwardly protruding neck opening. A drinking dish, or bowl, includes an opening in its bottom surface and is positioned over the container such that the container's neck opening protrudes into the drinking bowl. A "push-pull" cap having a first, closed position and a second, opened position is positioned within the drinking bowl and attached to the neck opening of the container. A tube (i.e., a "straw") is attached to the underside of the cap and extends downward, through the neck opening toward the bottom of the container. The neck and the cap may include threaded surfaces for ease of attachment.
