Jonathan Kirschner readily admits that the idea for the initial prototype of WaterDog was born mostly out of laziness. Romeo, Kirschner's Great Dane, would often beg his owner for a drink during their daily walks. While he was happy to oblige and open a few spigots, Kirschner couldn't help but feel there was an easier way. A mechanical engineer, Kirschner rigged an automatic fountain that connected with his outdoor spigot, and the WaterDog was born.
The refined design has come a long way from Kirschner's first attempt, adding features like adjustable height, chew-resistant materials and a low battery warning light. As a dog approaches, the water begins to flow, curtailing its own current as soon as the pet steps away. The design allows users to split the stream for a hose attachment and erect a remote station through an extended hose. Best of all, because the water is running from a fresh water source, it's tastier than bowl water, which can grow stale under the elements.
WaterDog is available from their online shop for $70.
