PetSafe Stationary Bark Control PBC-1000

This tastefully designed tabletop device can help safely control your dogs barking from up to 25 feet away. Whenever your pal barks, a 2-second ultrasonic tone correction can be delivered either automatically or manually your choice. No receiver collar is necessary, but your furry friend will learn to associate his barking behaviour with the unpleasant sound (that only he can hear) in no time.
