A pet water dish designed to retain water when repeatedly overturned. One embodiment of the invention utilizes two annular chambers separated by a flat base, and having an aperture allowing water to flow from one chamber into a reservoir when the respective chamber is upright and also allow water to flow back into the chamber when the bowl is inverted. The pet water dish may be inverted repeatedly, and each time, most or all of the water is retained in the dish. This helps ensure that the pet will always have drinking water available.
