They know

In a dimly lit room, a man with a beard lies in the foreground, appearing to sleep or be unconscious, while two other men stand behind him; one shirtless man leans forward and then moves out of frame, and the camera shifts to a close-up of the sleeping man's face. The scene abruptly cuts to a dog with its mouth wide open, baring its teeth in a snarl or yawn, before returning to a close-up of the man's face from a different angle.
