The footage, which was published on TMZ today, was recorded during the production of family film A Dog’s Purpose and features a German Shepherd named Hercules being lowered into the water as he makes repeated attempts to climb out. A second shot shows Hercules appear to go under the water, at which point production staff shout cut, and handlers scramble to reach him. TMZ says the white water effect was achieved with eight outboard motors in a closed pool, and claims that director Lasse Hallström was present at the time.
