DogRook Bark Control Collar - New

I'm selling a brand new DogRook Bark Control Collar, model DR-0040B! It's a humane training method that uses vibration and sound. The system includes: - Bark control unit - Adjustable reflective collar - 2 x batteries - 2 x plastic covers (black, pink) - 2 sets of plastic probes - Instruction It's recommended for dogs from 11 lbs to 110 lbs or more, and the high-quality nylon strap adjusts from 9 to 22 inches. I use them with my little yappy dogs when I need them to stay quiet. It doesn't hurt them at all. On first bark it beeps a warning. On second bark it vibrates. They quickly learn what the beep means. I no longer need to turn it on, as they are quiet whenever I put it on them 😉
