Review on 🐶 Rechargeable Dog Bark Collar with Beep Vibration Shock - Humane Anti-Bark Collar for Small Medium Large Dogs - 5 Adjustable Sensitivity Levels - Effective Dog Training Device by Sarah Foreman

The collar is very adjustable and fits my 6 month old pug perfectly with plenty of room to grow. We set the sensitivity to 4 and it does its job well. It gets more sensitive the more times it's turned on, which we actually like. Some reviewers complained that it could be activated by other dogs or human voices. I only experienced this after my dog barked continuously for over ten minutes. However, she has learned to be quiet when the collar is on and continues to bark when it is off. The battery lasts about three days with constant use. I would suggest that if your dog barks less, it will last longer. 😂The shocks are like static electricity and everyone in my family was shocked by it before applying it to the dog. You can also set it to only vibrate when you want it to.
