Free Spirit Indoor/Outdoor Bark Control System

Free Spirit Indoor/Outdoor Bark Control System | PetSmart

The Free Spirit Indoor/Outdoor Bark Control system helps stop nuisance dog barking using ultrasonic tones only dogs can hear. When the dog stops barking, the ultrasonic tone also stops – allowing the dog to associate its bark with the unpleasant noise. The Free Spirit Indoor/Outdoor Bark Control has 3 range levels to choose from, with the highest range effective up to 50 ft. Coverage can be extended with the purchase of additional Free Spirit Indoor/Outdoor Bark Control units.
