Some dogs will actually try to find a new family that will adopt it.
Dogs also have a tendency to run away if they become too emotionally dependent with their master.
The dog might go out of the house and try to find its master when it realizes that it has been left alone.

Dogs will normally bark or whine if it is left alone by its master in an area that does not permit escape.
