Suggestion:

Some cities have nuisance laws regarding dog barking. Why first arm yourself with the law. If you find you have the law on your side then before doing anything legally just kindly speak with your neighbors. Let them know what happening and see if they take any action to stop the problem. Take careful notes regarding the conversation. If they don't follow thru then the next move is to take the proper legal action based on your legal rights.
