I just want to say that I am generally opposed to physically correcting your dog by spanking or whatever. I just don't think that it is necessary, when usually just a snap of the fingers or a "no" will do. I really like the dog whisperers techniques and I think that he is amazing with dogs. That's generally the approach that I take. However, I have been seeing a lot of people lately promoting "no-negative" training. This technique considers any sort of correction to be a punishment and they suggest using no corrections whatsoever and only using positive reinforcement when your dog is doing the right thing. I am not opposed to this technique, but I am wondering how effective this could be. It seems that this method would take a lot longer for your dog to catch on. Also, I wonder what you are supposed to do if your dogs are fighting if you are not to correct them? Does anyone have any experience training with this method, and is it effective?
