Is dog obedience training worth the money?

I greatly enjoyed going to my first obedience class, back when dinosaurs roamed the earth. Today, I’d do things a little differently. I’d go to watch a few classes before I paid my fee, to see if I liked the methods by which the dogs were being trained. For example, does it seem too rough? What is the main training tool, a choke chains, or a clicker? Something else?

It is no secret that I favor clicker training but that is not to say that other methods don’t work, too. I would prefer to keep training as much fun as possible for my dog and I, without using avoidance techniques. You’re entitled to your opinion, too.
