The PetSafe Ultrasonic Bark Control is activated by the dogs bark or manually by the owner. Excessive barking can cause a real strain on the owner/pet relationship. The Ultrasonic Bark Control unit controls indoor barking and no collar is needed!

This tastefully designed tabletop bark control device can help safely control your dog�s barking from up to 25 feet away. Whenever your pet barks, a 2-second ultrasonic tone correction can be delivered either automatically or manually � your choice. No receiver collar is necessary, but your dog will learn to associate his barking with the unpleasant sound that is inaudible to most humans.
