My neigbor's dogs are barking in the middle of the night, and I can't get to sleep what should I do?

Do you have a Home owners accosiation as i see you are in the US they have rules and regulations about dogs being a nusicance and barking if you dont have a HOA, check city laws governing noise levels, barking pets, or nuisances. When these laws exist, contact the authorities, generally your police department. Do not call 911, since a neighbor’s barking dog is not an emergency. Call the police department or animal control during regular business hours on their business phone number. You may want to check back with the more approachable neighbor if the problem of the neighbor’s barking dog has not been remedied. Give about a one to two week interval, after first contact.
