Claim:
A portable drinking device for pets, comprising: a rigid wall structure which provides a drinking bowl at its top, partially encloses a water reservoir below the drinking bowl, and has an opening at its bottom; a water outlet passage which starts in the water reservoir, and leads into the drinking bowl; a water outlet valve which is arranged in the water outlet passage, normally closes the water outlet passage, and comprises an actuation element which, when operated, actuates the water outlet valve to open the water outlet passage; a removable closure element which closes the opening at the bottom of the wall structure and thus the water reservoir in a water-tight way, and includes an elastically deformable wall which, when pushed in, operates the actuation element of the water outlet valve and presses water out of the water reservoir through the opened outlet passage into the drinking bowl; and an air inlet valve which is a no-return valve and leads from outside the drinking bowl into the water reservoir, wherein the wall structure provides a top and lateral enclosure of the water reservoir, wherein the closure element provides a bottom enclosure of the water reservoir, and wherein the closure element essentially consists of an elastic body which includes the elastically deformable wall and comprises a rim including a sealing groove accepting a bottom edge of the wall structure.
