Dog training and barker collar

This is a brand new in the box. Dog training and Barker breaker collar. also trains dogs for house train8ng.It has different settings from a vibrating setting up to a shocking setting. But the shocking setting is not needed. I have found that as soon as they feel the vibration. They stop barking. But every dog is different. This is brand new in the box with the instructions. And everything is included. The collar is adjustable so can be used for pretty much. Any sized dog it says on the box suitable for all breeds. I had another one that I used on my Chihuahua. And I would never have another Chihuahua. Without having one of these first. I saw a difference in a couple of days. she is not an overly barking dog anymore. It is wonderful.brand new in the box
