Abstract: A water bottle in accordance with this invention comprises a liquid container, which may be identical to the containers presently used in known portable water bottles, and a lid assembly attached to the container and covering an upper opening therein. The lid assembly has an opening through which a flexible tube extends. The lid assembly has an upstanding wall that defines a liquid reservoir surrounding the straw separate from the liquid container. The lid assembly defines a path for the tube that is disposed exterior to an interior sidewall of the reservoir. The liquid reservoir may be filled with liquid from the container by directing the upper end of the straw into the reservoir and squeezing the container to force the liquid therein through the straw. This provides an open reservoir of liquid from which a pet can drink without contaminating the liquid within the liquid container.
