Anti-Bark Collar for Small Dogs : Take control of your dog's excessive barking with our anti-bark collar. As a training tool, it uses vibrations or a beep to interrupt the barking pattern, providing a negative stimulus. Over time, your dog will understand that excessive barking is not the desired behavior and will naturally reduce the frequency of barking. Simple Training Modes : This anti-bark collar for small dogs offers sound + vibration. During the first two barks, there will be only a beep, and during subsequent barks, the vibration will be added to the beep. The combination of sound and vibration can effectively and safely stop your dog's barking. 7 Adjustable Sensitivity Levels : Adjustable according to the environment: 5-7 for quiet environments and 1-4 for noisy environments. The higher the sensitivity, the easier it is to trigger the collar. Choose the most effective combination according to your dog's needs and usage conditions. Adjustable Size : This anti-bark collar is
