Canine Caddy (1941)

Mickey's going golfing, and Pluto is his caddie. Besides the usual caddie duties, Pluto runs to the ball and points to it. But when the ball lands in a gopher hole, Pluto's got another task: chase the gopher. They eventually chase each other through a number of holes in a knoll where Mickey is trying to putt out, causing the knoll to collapse.—Jon Reeves
