This tabletop device can help safely control your dog’s barking from up to 25 feet away (about the size of 1-2 rooms in a typical house). Simply put it on a table or counter in the room where your dog barks the most. Whenever your dog barks, all pets within range will hear a 2-second ultrasonic tone. You can can set it to go off automatically every time your dog barks or manually press a button to make the tone sound. Your dog will learn to associate his barking with the unpleasant high-pitched sound (inaudible to most humans). Most dogs bark less within a few days. Now there’s the answer to the problem barker!
