Review on Ropetty Dog Bark Collar with Beep Vibration - Rechargeable & Waterproof - Adjustable Sensitivity - No Shock - Anti Barking Device for Small Medium Large Dogs - Effective Training Collar by Jennifer Dammann

anti bark collar very adjustable and perfect for my 6 month old pug with LOTS 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 really 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.
