Sheila, The clicker makes one "click" sound. You start off with just clicking (once) and giving a treat. This can be done without the dog doing anything at the beginning. At first, you just "click" and treat, "click" and treat, over and over so the dog associates the "click" with the reward of the treat. Always give the dog the treat AFTER the "click" sound. Then, you start guiding the dog to do what you want, such as sit. As soon as the dog's bottom hits the ground, you "click". Then you give the treat. Do this over and over a few times and then start adding the voice command "sit". Most dogs pick it up really fast if they are food motivated. I don't think the age of the dog makes any difference. There are many classes out there that offer clicker training. Most dog training facilities use the clicker method in the puppy and basic obedience classes. You would just have to be careful with bringing a little Chi to a class with big dogs. Or...you can always train your own dogs! Hope this helps! Stef
