Review on 🐶 Waterproof Rechargeable Dog Training Collar with Remote – Dual Dog System, Electric Dog Shock Collar with Beep Vibration & Adjustable Safe Shock Levels, Suitable for Small Medium Large Dogs - 0 to 99 Levels of Training Set… by Ashley Varela

I love that this easy to use control can call both dogs at once. Set any vibration strength you want, there are 99 levels so start with the lowest level and increase according to your dog's reaction as not all dogs react the same. This product comes with devices already charged so I don't have to wait to use it which is a huge plus in my books! Simple snap collar, adjustable and durable. Very easy to understand instructions. Remember to always read all instructions before trying on your pet. You might just learn something new. I'm watching a video on how to train a dog with training collars. I just love these collars!
