YouTube user Beating Heart plays ping-pong with their dog.
The border collie is amazingly skilled at the game. Clenching a paddle in its teeth, the dog effortlessly taps the served balls back to its owner. Throughout the match, it emits a cacophony of yelps and growls (which is probably how John McEnroe also played).
