I was awakened at 4:30 am by a ringing bell.
My first collie, as well as being my first "used" collie, arrived with the instruction that she rang a bell when she needed to go out. And after she proved to me that a bell was the only way she knew how to ask to be let out, we got a parrot bell and hung it on the door. Subsequently all of the collies at our house learns to ring the bell to go out.
Milo rang the bell because he needed to go out.
Good boy Milo!!
