The traditional way these stunning dog collar leather are used by professional trainers is to give a sharp jerk—strong enough to make the dog stop what it's doing and do something else. For instance, if the dog starts to sniff and pull on a walk, you quickly brace yourself and give a quick yank in the hopes that the dog feels it enough to stop pulling. My first trainer told us to generate enough strength by actually running full speed in the opposite direction so that my, then 76 pound boxer, would feel a strong enough pop! The next trainer I had taught me to first attach the leash to a fence so that I could practice the technique and get it right before I tried it on the dog. The technique was a lot like karate where you have to twist your hip to get enough power for your body and so that you can get the timing of the correction right. Most trainers do not give owners practice on a fence first. They just let owners make a lot of mistakes on the dog.
With the stunning dog collar leather, the idea is that once the dog knows he’ll get a strong correction when he misbehaves, you don't need to continue to give strong corrections often; a light correction, may be good enough because it's a reminder that a stronger, more painful correction can occur. In fact, it's this phenomenon, with the use of a lighter warning correction that makes some people think that it's the sound of the collar being jerked that teaches the dog, as if there’s something innately aversive about the sound. If that were true, then you’d be able to train dogs with a recording of the sound of a stunning dog collar leather snapping, even if the dog had never received a stunning dog collar leather correction before and was not sound sensitive. In other words, if that were true, someone who could have developed a little device that dogs can wear on their leash or flat collar that makes the sound of a stunning dog collar leather snapping would be rich!
