There's a guy named Hassan who is marketing his training biz under the name Sit Means Sit. He claims to be a positive trainer, but he isn't using a training technique that you will find at trulydogfriendly.com! The name of his game is the shock collar. Don't like the terminology? Tough. I don't like an e-collar trainer calling himself "positive" to fool the public either. Does e-collar training work? Sure it does, and Mr. Hassan will be only too glad to show you the videos. But, take a closer look at this method. It gets the dog to behave in order to avoid a penalty, which these people will tell you is a "stim", or stimulus. Well, in plain talk, the "stim" is an electric shock. Granted, the shock can be minimal, but if the dog does not respond, the "stim" gets stronger until he does. Personally, I don't mind spending more time training my dogs with more positive (really positive) means, and I don't want them to work to avoid a penalty, or to avoid pain. That produces a dog that's basically an automaton. I like a dog that understands how to learn! That's why I choose clicker training over e-collar, or any other type of correction training. I want my dog to exhibit behavior because there's a reward in it for him, whether that be food, a toy, praise from me, or something else that my dog is willing to work for. I want a willing partner, not a dog that is coerced to work because he will be in pain if he doesn't. Sure, e-collar training works, but is it the most humane choice? I think that's a big fat NO. Buyer beware. Make sure anything labeled "positive" really is positive before you subject your dog to it..
