Review on 🐶 Enhance Dog Training with Rechargeable Shock Collar - 2 Receivers, Remote Control, Beep, Vibration, and Shock Modes by April Martin

That's a great thing! It comes with two collars, a remote control and a charging cable that can charge the collar and remote control at the same time. After reading the instructions it is really easy to use and I love the fact that there is only one remote control for two collars. It fits my 65 year old pit bull perfectly. And she's definitely learning to stop jumping on the fence after a few vibrations. I only had to use the shock method once! I even shocked myself before putting it on her and the first stage doesn't hurt. It just makes your muscles twitch a little.
