Review on 🐶 PetSpy P620 Extra Receiver Collar - Replacement Component for P620 and P620B Dog Training Collars by Dawn Wright

I bought this collar along with another collar and phone because I have 2 rottweilers. I didn't have to use the shock button as the vibration got her attention as soon as possible. But he's there when I need him when they decide to follow a car or truck down our gravel road. They figured out what was going on very quickly and I didn't let them just vibrate the truck from day one. Great tool for training and now I have completely different dogs. We live on a private road that is owned by us. We have a lot of traffic looking for a river access although all the signs are up. I got this so they stop chasing those invading cars and trucks and maybe get hurt or run over. It worked wonders for her. They also come when they are called now; Which used to be a problem with our 22 acres. Great product and I can only recommend it.
