Another fact about the marvelous nice dog collars is that most people use them ineffectively because they are not that easy to use and there are some secrets that the old time professionals used to make them more effective and the correction stronger. First, these professionals make sure the length is right or you won't get the strong, quick pop. If the chain’s too long, when you go to give a correction, there’s too much slack. When it's too short, the collar tightens too quickly, before you’ve gained enough momentum in the jerk. Seasoned trainers also know that dog's feel the correction more if you can keep the marvelous nice dog collars up high, right behind the ears. That’s how Cesar Milan’s Illusion collar works. It keeps the collar positioned so that a correction can have the greatest effect (e.g. create the most effective jerk). Back when I was competing in obedience we didn't have Illusion collars and they wouldn't be allowed in the ring now anyway, but we did try to keep that marvelous nice dog collars up high when we were training. A third point, but one that’s the first thing a seasoned professional trains is that the marvelous nice dog collars has to go on the right way. It needs to form a “P,” with the tail of the “P” on the same side as the handler. You can tell right away when a force-based trainer isn't good at his marvelous nice dog collars technique because he doesn't even put the collar on correctly.

Before I tell you why, let me first explain how a marvelous nice dog collars is used.
