Totally agree. I use a prong collar almost daily and my dogs go NUTS when they see it. So obviously it's not causing them harm. They know it means we're going to work (which they love) or just walk, which of course they love too. But I was trained on how to use it. It's almost as if they shouldn't be sold to the public, but you can earn the right to buy one with training. Like a drivers license ;)
