Wow, that's a tough one. We had a neighbor call us anomously one time because Oreo was barking DURING the day and they were trying to sleep - we rarely let our dogs bark more than a few minutes unless we cannot get to them for some reason. I guess because you don't know the neighbors, I might call the police. But if you want quicker relief, I guess I would go over and ring the bell. A lot of help I am, huh?
