Review on 🐶 Dr.Trainer B1s Dog Bark Collar with APP Control | Waterproof Training Collar | 3 Modes (Vibration/ Beep/ Shock) | Adjustable 0-99 Static Level | Rechargeable Dog Barking Collar by Randy Gunnmann

Excellent collar. The first one I bought was defective from the start. But I liked the app and the way it was structured so much that I wanted to give it another try. I ended up getting two more for my two pit bulls. I insisted on not using the shock feature but after a few weeks one of our dogs became too stubborn and wouldn't stop barking from the vibration so we had to turn on the shock. However, I lost the second collar one night while taking it off the dog. I swear she must have hidden it. I would like to somehow track this from within the application. But I turned it off so I couldn't call sound from the app. It looks like it was thrown in the trash somehow as we've been looking for it for over a month. I need another one but really don't want to buy a third one lol.
