PetSafe - Outdoor Dog Bark Control, Birdhouse

In Original Box !! Stop outdoor nuisance barking with a decorative touch. The PetSafe Outdoor Bark Control unit looks like any ordinary birdhouse and can be hung or mounted to a tree, a wall or fence post to keep your dog or your neighbor's dog from barking. The unit emits a high-pitched, ultrasonic sound that will stop barking up to 50 feet away. When in range, an internal microphone picks up the sound of constant barking and activates the unit. It emits an ultrasonic sound that can only be heard by dogs, who will be startled by the high-pitched sound and associate their bark with the unpleasant noise. The unit has four settings including three sensitivity levels and a test mode. Safe and effective for all sizes and breeds of dogs. Offers Welcome!!
