Vastar® VDS25 No Bark Dog Collar Electric Advanced Anti Bark Shock Control Collar with 7 Levels Button Adjustable Sensitivity Control, No Harm Warning Beep and Shock

This New Model VDS25 Vastar Anti-Bark Collar improved with a better senser and control chip. It helps to effectively stop barking by progressively increasing sound and shock which is controlled by a microprocessor distinguishing your dog's bark from other environmental noises and automatically delivers sound and shock after each bark, most of the pets will quickly understand the new sensation is telling her to be quiet.

How to it works:

At the first bark, the Collar applies a short warning tone . if a second bark occurs within thirty seconds, a more intense tone is sounded. From the third bark, a more intense tone is sounded along with a short , mild shock. This pattern is repeated through 7 correction levels. The first two levels are only with progressively warning tone.
If your dog continues to bark through the rest five levels, the more intense sound and shock are applies until your dog stops for thirty seconds, and then it will automatically resets to the first "tone only" level of correction. If the continuous stimulus reaches the 7 levels, then the Collar will stop working for 1 minutes to protect the dog.
