Cleverly disguised as a bird house, whenever your dog (or worse, your neighbor’s dog) barks within the range of the Outdoor Bark Control (50 foot radius), an internal microphone picks up the sound. The PetSafe Outdoor Bark Control then goes to work, releasing a high pitched squeal. The frequency of the sound can be heard by dogs but not humans. The dog will be startled by the high-pitched sound and stop barking. After several attempts at barking with the same response the dog will learn to associate its bark with this unpleasant but 100% harmless noise. When the dog stops barking the ultrasonic sound also stops. The PetSafe Outdoor Bark Control has three settings to control what level of barking activates the unit. It also has a test mode.
This product is great. I use it indoor and out to stop my dog from barking. The first time my dog barked with it on, she stopped immediately. I brought it to a neighbor for her to see how great it was. The dog next door barked and then stopped immediately and ran away. This is such agreat product.
