The magic switch, the wand wave, the erase button: these all come up in classes or privates and it's common for folks to look for a quick fix. It makes me think about an author named Brandon Sanderson (New York Times best seller) and his Second Law of Magic: limitations are greater than the power. Which means there is always a weakness or cost associated with magic. For example, Gandalf (in Lord of the Rings by JRR Tolkien) defeated the Belrog but at a great price to himself (death.) Meaning the magic he performed had a great cost.
What the heck does this have to do with dog training?
Well a lot actually. There are companies that take advantage of this magic seeking and sell products like ecollars and other aversive training methods. An aversive may impact dog behavior but the overall cost isn't worth paying. When you send an electric current through the artery of a dog there is a great cost. There is damage to the relationship, the dog's trust of you, and an even bigger price of causing a possible negative association to whatever you shocked them for. Meaning that if a dog is harmed every time they bark at another dog, they most likely will start associating dogs with pain. Meaning that your dog may not have been aggressive, but you are now creating an aggressive dog. Magic comes with a price, always.
Positive Reinforcement also comes with a price. However, it's one I'm willing to pay. When I found agility many years ago, I watched fast flashy dogs run over, around, and through everything they were asked to. I fell in love with the sport and wanted to start right away. What I didn't realize was the cost. Not the monetary cost, but rather the sweat equity cost that came with training my young brilliant and very distracted/over aroused/wild/beautiful hound. So I became frustrated when a few months training really wasn't even making a dimple in the surface. We didn't have a good foundation and our training time together hadn't been equal to the magic I wanted. The magic did come with a very great time equity cost. AND IT WAS WORTH EVERY MOMENT.
So when you start looking for magic, remind yourself that there is a cost. Take a giant step back and really think about the price you are willing to pay in training. The best moments, come with hours of time, sweat, and understanding with your dog. Magic comes with a price, just make sure it's a price you are willing to pay.
