Abstract: A water cooler for pets for providing a source of cool drinking water for pets. The inventive device includes a cooling member, such as a refreezable ice pack, and a bottle having a top and a bottom, wherein the bottle includes a neck portion extending downward from the bottom and a cavity open to the top, wherein the cavity is adapted for receiving the cooling member. A base member is provided and includes a port adapted for receiving the neck portion of the bottle, a water basin, and a channel interconnecting the port and the water basin. The cooling member cools water disposed within the bottle such that when a pet consumes water from the water basin, the water basin is replenished with cooled water from the bottle.
