The Spray Bark Control collars use a lemon or citrus spray burst to discourage a dogs barking behavior. These collars do require a battery and can be refilled with the spray. Usually these units will last around 30-50 sprays per fill and can be refilled when empty. These anti bark devices are considered to be a safe alternative to static bark collars.
