Soo.. The dog I was bitching about the other day, neighbor's dog that barks for hours at absolutely nothing.. (I've watched, it really is barking at nothing)
Turns out a few other neighbors are hearing it and getting annoyed about it. So, if people start complaining to the cops or the city, what will they do? Fine the neighbor? They can't really come and take his dog or force him to get rid of it so, legit question; what happens in such a case?
I'd say you should contact animal control on that more then the law enforcement, worst thing I think though that can happen is they get a fine.
might depend on where you live also, if there are any kind of local ordinances or laws you can cite them.
