Both dogs are wearing Elizabethan collars while facing each-other, so we can't see what they are doing. The caption implies that they are playing tug of war over a stick --- the stick is in both of their mouths. It's funny because the caption paints a vivid picture of what's happening, but it's obscured, so it requires visual imagination.
