Have you ever used a shock collar?

Would you put a shock collar on your kids? I mean, if it's safe and harmless for dogs, it should be safe and harmless for humans too, right?

I would never use a shock collar on an animal. Who knows what kind of damage it causes them, both short term and long term. I doubt the manufacturers of these products are entirely up front about how safe they are. It just seems like a cruel way to try and get your dog to follow your commands. Plus, what happens when the power goes out or something while you are away?

I would never want to stress an animal out like that.
