The PetSafe® PCB00-11005 Spray Bark Control Collar effectively stops barking when it isworn. The Bark Control Collar has a unique patented sensor that providesthe most reliable bark detection available. The Bark Control Collar uses bothvibration and sound sensors (dual-detection) to discriminate each bark fromother external noises. A burst of lemon-scented spray is emitted to deter barkingonly if both the vibration from vocal chords and the sound from the bark matchthe same criteria.
