If you have a neighbors dog that won't shut up and quit barking and keeping you up at night or barking at you while you're in your yard then you will need to either call animal control if they have animal control in your area or call or contact the mayor.
If you don't have animal control then look up your mayors phone number and sometimes you'll be able to contact the mayor directly through their cell phone number and then you can make a complaint to the mayor about the issue.
Or you could show up at the next scheduled town or city meeting and voice your concerns at the meeting in front of the city council and mayor.
Sometimes the town may not yet have a noise ordinance in place and may need to put one in place and then the issue about the dogs barking can be enforced.
If the neighbors dog gets out of control and begins being aggressive and tries to attack you then contact 911 so that police can intervene.
But if it's just dogs barking then there's usually not much a police officer can do about the dog barking unless there's a noise ordinance that the dog is breaking.
