I call a prong collar "Power Steering for Dogs." A prong is probably the most misunderstood training tool there is in dog work, next to the whip. So many people take one look at it and say "Oh! I could NEVER use that on MY DOG!" Then when I explain how its used and why it is used they call back and say "Ed, this is the greatest thing since sliced bread!"
I also get asked if a prong collar is appropriate for puppies. The answer is very simple. If properly used, a prong is one of the most humane and effect training tools there are. Can it be abused? Absolutely. Any training tool can be abused. If you want to learn how to train with a prong collar get my 4 hour training DVD titled Basic Dog Obedience.
When a prong collar is used in training, the handler must first realize that a dog who required a level 8 correction before will now, with a prong, probably require a level 2 or level 3 correction. What this means is that a strong dog that had so much drive that it was too much for a small person to handle is now easily controllable without a lot of effort.
If you are a new Schutzhund trainer or a police service dog handler, you are going to need a prong collar.
The first people I usually recommend for the prong collars have 3 to 4 month old pups that pull them down the street when they take them for a walk. These dogs need a prong. There is no correction needed from the handler when a prong is worn during walks. The pup (or dog) gives itself a correction when he hits the end of the leash.
When this happens, the handler is there to soothe the shock with praise if the pup yelps. Within one training session every dog is going to be walking slowly by his handler, there is no longer any pulling. In addition the handler is not the bad guy in this work. How could he be? He is soothing and praising the dog after it yelped from a self induced correction when it hit the end of the leash?
Older dogs sometimes need a prong collar when normal corrections with a choke collar do not have the intended results (which means they do not effect the dog). My feeling is that any time a dog required a level 7 correction for normal training, he needs to be worked with a prong collar from that point on.
It's the job of the handler to read his dog. New handlers tend to go out and give the same level of correction with a prong that they did with a choke collar. This is unfair to the dog.
A prong collar is designed to be snug, almost tight, on the dogs neck. Many handlers need to take a link or two out of the collar to get the correct fit. Keep these links if you have a young dog, you will probably need to use them when the dog grows up. The point is that if a prong collar is too loose on a dogs neck, the collar loses its effectiveness.
Some dogs have very large necks, if you have such a dog you may have to purchase additional links for the collars. They are sold separately.
