Pet Safe Deluxe Outdoor Bark Control House

Noisiest dog on the block? Hang this ultrasonic bark controller in your yard, and Buddy will quickly pipe down! Looks like a decorative birdhouse, but powerful enough to cover up to a quarter-acre yard. Whenever your dog barks, it emits an unpleasant, high-pitched tone that only dogs can hear. When the bark-fest stops, the sound does, too—a lesson most dogs learn quickly. (If your neighbors' dogs are within range, they'll learn, too.) Weatherproof, with a 50-foot transmission range, digital timer, and low-battery indicator. For outdoor use only. Uses 1 9-volt battery (not included). 8" h x 6" w x 6" l.
