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 Erika Martinez

I have 3 dogs who love to bark at everything! When one barks, all three begin to invade. I got tired of yelling at them to "shut up" and ordered 3 of these collars. We wore them for about 20 minutes so I'll give you our first impressions. My husband went outside. and rang the doorbell. 2 out of 3 of my dogs stopped immediately when they heard the beep. It's like frozen! My 3rd dog (usually the smartest) hasn't figured it out yet and will bark during the beep, vibration and shock so he goes through quite a few cycles. Hopefully over time he'll understand what it's for. His bark didn't activate the other collars. Only yours. I have a sensitivity of 2. When they play they growl at each other. The game's growl doesn't trigger the collar, which I'm really happy about. Someone else rang the doorbell and the 1st dog didn't even get up, the 2nd dog checked but stayed behind and didn't bark, and the 3rd dog barked all the time. I hope these collars will work for them. I will post an update.
