Barking can also be a sign of fear. Because it’s darker and there are fewer visual stimuli, dogs feel more vulnerable at night. This can generate anxiety that expresses itself through barking.

If a dog senses something isn’t right, or that it’s not in control of the situation, it may start barking, and if other nearby dogs sense the same thing, they’ll follow suit.
