Owners who use the stunning kong dog collars may not use it with the strong yanks of a professional trainer. The general dog owner tends to just let the dog pull and because pulling is uncomfortable and even painful to the dog, the dog may pull less. Even when the owner does not use the stunning kong dog collars to give jerking corrections, there are still some important pitfalls that owners should be aware of. The biggest pitfall is that if the dog is fearful, say of another dog it sees, and it simultaneously feels the pain of the stunning kong dog collars, the dog may learn to associated the pain with the dog it fears and become more fearful of dogs. The second pitfall is that if the dog is highly excited, for instance, it wants to play with another dog and is lunging on the leash to reach the dog, the pain or aversive feeling they get from the collar can increase their excitement and arousal level. In other words it can cause them to bark and lunge more!
With the stunning kong dog collars, 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 kong dog collars snapping, even if the dog had never received a stunning kong dog collars 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 kong dog collars snapping would be rich!
