Jerry likes to fetch balls. We’re guessing he can do it for hours on end, and perhaps that’s why his owner built this ball machine. Jerry ain’t your average dog, either. In no time flat he figured out that putting the ball back in the machine would result in more play time. Jerry’s owner built the machine from scratch and even implemented a proximity sensor to protect both his dog and infant son. From what we can gather, Jerry has since passed away, but we’ll never forget his happy disposition and tiny little legs.
