PetSafe Outdoor Bark Control - Available Online at petco.com
When the Outdoor Bark Control is within range of a barking dog, an internal microphone picks up the sound and the unit is automatically activated. The PetSafe® Outdoor Bark Control emits an ultrasonic sound. The ultrasonic sound can be heard by dogs but is silent to humans. Startled by the high-pitched sound that is safe and effective, the dog should stop barking, as it will associate its bark with this unpleasant noise. When the dog stops barking the ultrasonic sound also stops. The PetSafe® Outdoor Bark Control has 3 sensitivity levels to choose from that indicate what barking level activates the unit and a test mode. It is effective up to 50 feet. Operates on a 9 volt battery (sold separately).
The PetSafe® Outdoor Bark Control should be placed facing the dog and within range of the dog. The unit is designed with provisions for hanging or mounting and should be positioned at a height of no more than 5 feet. The Outdoor Bark Control can also stand alone. It can be placed in a tree, hanging from a pole, on a fence post, etc. For best results, the area between the Outdoor Bark Control and the dog should be free of any large obstacles.
Place the PetSafe® Outdoor Bark Control within range of the dog with the unit switched to Low, Medium or High Sensitivity. Most dogs will understand very quickly that the Outdoor Bark Control is disrupting their urge to bark and will relax and stop barking. You should notice a reduction in the dog's barking within the first two weeks that the Outdoor Bark Control is in use. Please note this product may not work on deaf or hearing impaired dogs.
Has 3 levels of sensitivity:
Level 1 - up to 15 feet
