Pet Safe Indoor Bark Control

Stop your dog from barking inside your home, apartment or condo! This clever device uses safe, proven ultrasonic technology to stop noisy, nuisance behavior. Whenever your dog barks, it emits an unpleasant, high-pitched tone that only dogs can hear. As soon as pups go silent, so does the sound—a lesson most dogs learn quickly. Place the device on a table or mount to a wall (adhesive-backed hooks included) in the room where your dog barks most. 25-foot transmission range. Water-resistant, with low-battery indicator. For all size dogs. Uses 2 CR-2032 batteries (included). 2 3/4" h x 1 3/4" w x 1 1/4" d.
