Petsafe Outdoor Bark Control Birdhouse

If your dog (or your neighbors) is driving you bonkers with his barking, help is here! Our ultrasonic outdoor bark control unit looks like an ordinary birdhouse that can hang in a tree, on a fence post, or anywhere outside. It can detect barking up to 50 feet away and has 3 range settings. Whenever the dog barks, he will hear the high-pitched sound (inaudible to humans) that will teach him to stop his annoying habit. It features 4 levels of operation, runs on a 9V battery with a low battery indicator light, and it is durable and weatherproof.
