LOL! They use the term "throw chain" instead of "choke chain" or "choker."
Yes, the method has been around forever, and most of us who have been around awhile have deliberately or inadvertently use the methods. They do work.
Just because something has been around forever and gives results, does not mean there aren't better overall methods for training dogs.
Dog training works when the communication is effective. If the dog understands that what he just did was what you want, he is likely to repeat it. Communication includes timing, praise, reward, body language. A lot of dog training is training/disciplining the handler. If you can make your body do the same routine, the dog is going to learn much quicker. If you can make your body language work to cause a dog to naturally perform the desired trait, training becomes much easier.
For example, raising the treat up above the dog's head so that to follow it, his hind quarters must go down, and the sit is accomplished. That movement of your hand becomes the sign for sit, and it is close to natural -- this is not the Koehler method.
The Koehler Method works because it is repetitious and consistent. The idea of repeating something 25x every night is ridiculous though.
I just think there are better ways to bond with your dog and teach him what is expected. Choke chains have their place. I have used them in shows where corrections are not allowed. Once the dog is trained, a martingale or a choke chain can be interchangeable. Training a dog with a choke can cause damage...
Interesting what they say about e-collars.
