Ultrasonic Bark Control System

Barking no more. You've seen a lot of dog collar out there that stop your dog from barking. But our little dog it seem to put too much added weight around her neck. Even though we only put it on when we would leave for a few hours. That's the only time that she gets out of control. We just found this new one though that not a collar its just a little box. We set it in the hallway where she is. If she barks for more than twenty seconds it sends out a tone which is softer than the collar tone. But it still warns her to stop barking.
