Abstract: An improved watering dish is provided for use with dogs and other animals. The watering dish is self-cleaning, and is provided with a float-activated valve that automatically replenishes the water supply in the drinking reservoir as that supply is depleted. The float is constructed so that it will not flip or otherwise become fouled, even if the watering dish is overturned. The valve is constructed so that it may be shipped as a separate element, but readily snaps into position in the watering dish during assembly and is thereafter essentially permanently fixed into place in an orientation conducive to the optimal performance of the device. The watering dish is also provided with fastening elements that permit it to be affixed to both vertical and horizontal substrates. The fastening means also allow the device to be attached to both hard and soft surfaces.

Abstract: This invention is a watering device particularly adapted for use by animals. A valve is provided for maintaining the liquid level within the reservoir and the entire device is so designed that it cannot be accidentally upset by the animal. A valve having a pressure chamber to control a diaphragm permits the watering device to be compact.
