It is illegal to let your dog bark after 6 PM.

The Law

Under various state and local noise ordinances read a bit too strictly, dogs are legally prohibited from barking loudly after 6 PM. In reality, authorities enforce nuisance animal laws where owners can be fined if their pets continuously disturb the peace during evening hours. The law exists to ensure neighborhood tranquility, placing the legal burden on the owner to quiet their vocal canines.
