Another clicker training fan here!! There is a specific method to using the clickers for training. I had always used the verbal and hand training with my other dogs, very slow process in my opinion. I used the clicker with aprillove and nappy and I was amazed at how quickly they pick up on it. After a certain skill or behavior is learned via the clicker than you transition that to verbal. I use the clicker now only when we are learning a new skill/behavior.
Check out this site, it will give you some good info on the method of clicker training.
