Review on Flittor Dog Training Collar: Waterproof Shock Collar with Remote for Small, Medium, Large Dogs - 2 Receiver Rechargeable, Beep, Vibration, Shock Modes by Julie Lee

Bought for my 2 year old Mini Schnauzer. Her barking pierces her ears. We borrowed a stun collar from my daughter and it worked wonders. Of course she needed him back. I ordered this. The first time we put it on her she knew what it was for. We let her out while the neighbors were in the yard, she usually goes nuts when she lights my gold. This time there is no sound from her and the golden one is silent and follows her example. Our daughter knocked on the door, our chihuahua was wearing a new vibrating collar and (hoping it would work) barked a little until it vibrated. My moustache let out a soft bark, I gave the command "quiet" and pressed the sound button. That's all it took. Our daughter knocked again, total silence from all four, yes four dogs. Chi and the younger Mini Schnauzer Bark, Golden is just a puppy and will learn from them. My 15 year old doesn't bark very loudly. I really hope this continues to work. But so far the first day is a success! Update 9/25/20 They were working fine until I saw the neck mark of a small mini schnauzer by a pip with a protector on it! She hasn't worn it in so long. As soon as we saw the mark on her neck, that was it. Done. I would rather find another teaching method. Seeing the mark on her neck made me very angry at my husband and I. I felt terrible. I'm glad we were still in the return window.
