Major has developed a new habit...barking...at night. He doesn't bark for us to come, he barks either because
It's become a habit
Or there is somebody outside.
At first I think it was because there was someone outside, a few houses down which there usually is nobody. However, I think it has become a habit for him to come out of the house and bark for an hour. Any suggestions? I don't want to use the shock collar.
