Review on 🐶 Advanced Training Collar for Dogs: Remote Control, 4 Humane Modes, 16 Levels, Rechargeable & Waterproof - 1000 Ft Range by Becky Guyer

I almost gave up because you really need to read the instructions before using it. But if you take a minute to read this, it's not hard to sync your remote and collar. And from the start my dog was obedient with it. I didn't even use shock. Just a beep or vibration and it comes instantly. It saved his life because I tried other collars but nothing worked. My dog loves to chase wild mother cows and I was afraid he would get a kick in the head. But not now. This, of course, helps him learn obedience. I'm so, so, so, so careful.
