The weak point of the clicker trainer's argument is in the assumption that using compulsion (giving a dog a correction) is the same as punishment and/or force. In reality, a well timed motivational correction is merely a method of telling the dog that he did something wrong. ( I guess you think that the mother dog uses "violence" on the puppies, too?) Imagine trying to learn how to drive a car with an instructor who only told you when you were doing something right. And refused to tell you when you were doing something wrong. Sure, you might eventually learn how to drive (if you didn't kill yourself first), but the fastest and easiest method of learning ANYTHING is to know when you are doing something right as well as when you are doing something wrong.

The prong collar is like power steering. It is a phenomenal tool for teaching your dog to walk on a loose leash, as well as allowing you to give your dog a motivational correction in a manner that gets your point across. (No pun intended). Used by anyone who knows how to use it, this training collar is safe and humane.
Our club tried clicker training and decided we weren't getting the desired results in the long run so we don't use it anymore, just think if you were ever caught without a clicker.

To each his own I guess. I would never use anything but a prong as it allows me to work any strong dog that comes along without losing an arm or hurting the dog. JMO
