Contact 311. Provide the call taker with as much information as possible such as: location, date, time of the incident, and specific details.
Regarding noise complaints, a letter is written to the owner and a copy to the complainant (the owner will not have your information). If the letter does not remedy the problem, the complainant is then advised to file a formal complaint with the Municipal Court. To file a formal complaint with the Municipal Court, the dog has to be recorded barking consecutively for fifteen (15) minutes or longer. Please fill out an Application for Outside Complaint if you are sending the information to the Municipal Court.
