dog training collar with walkie talkie Remote Control Distance Up to 3280Ft

Simple operationAfter using two weeks, I think this is the most useful remote collar I have bought. I have two dogs and they have very high energy every day. In order to stop them always fight with each other. I bought two training collar to use. It is very easy to pair two receivers and the remote together, so I can use one remote controller to control two dogs. But the training collar cannot be operated at the same time. If you want to train another dog, you need to swap from channel one to two. But it still very easy to operate.
