Pettags No Bark Dog Collar is a gentle yet effective way to reduce excessive barking in a humane way. Each collar comes with 2 correction modes. Vibration mode gives you a choice of settings which allows you to control the correction. You also have a sound mode that releases a high frequency sound that deters your dog from barking. Both methods are very humane in that NO electrical shock is used.
