Dog's intuition.

This is why our dog literally has a timer. At 5 p.m. he barks at me if I'm not ready to take him on his walk. He wakes my son up every morning so he can get my grandson on the bus. I swear he has an alarm clock inside him. He even knows when it's the weekends and we don't get up early. They truly are a blessing to all of us dog lovers.
