Your Dog is Hearing Strange Noises
One of the first theories that will come to owners’ minds is that the dog is barking because it hears strange sounds emanating from outdoors. It’s not a bad theory.

Some breeds need constant stimulation and exercise. If your dog isn’t getting enough of these in the course of a day, it may act out even at night while you are trying to sleep.
