Review on 🐶 DogRook Rechargeable Bark Collar - Humane, Non-Shock Solution - Vibration & Beep - Training for Small to Large Dogs - No Remote Control - 11-110 lbs by Cindy Jones

I love this collar! Before this collar, my deer-headed Chihuahua was a barking, aggressive nightmare. She was afraid and suspicious of everything and everyone. When my sister came to visit, I put a collar on her, she barked twice and calmed down. Yes! So I took it off her and said she was a very good girl. After 2 days of inactivity with collar and praise she sat on my sister's lap and made love to her. I recommend that you don't leave it on in case they stop barking. Praise them and only attract them when they misbehave. It is therefore ideal as a teaching tool. I love this collar!
