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.
