Review on 🐶 JSCLYAN Waterproof Dog Training Collar: Rechargeable Shock Collar for Medium & Large Dogs, 1600ft Range - Beep, Vibration, Shock Modes - Keypad Lock, Support for Training 3 Dogs by Kurt Virden

I can't believe how quickly my dog's behavior has changed. It may be very sensitive, but after a few hits on the lowest settings I was only able to switch to horn. A beep immediately forwards it. Make sure I prefaced any input into the collar with a "no" command. I originally bought this because he chased my older dog around the garden and bit his ears. In fact, they couldn't both be on the road at the same time. Now it's not a problem if it gets a little lively, usually no command is enough, sometimes a beep, but rarely. Used on walks, had to take a few light smacks when he went for squirrels etc. Not anymore, he's that good now. As said, maybe my dog is sensitive and doesn't like the beep, but this is a game changer. I highly recommend.
