You can clicker train any kind of animal, of any age. To get started, push and release the springy end of the clicker, making a two-toned click, then treat, keeping the treats small and delicious. Click during the desired behavior, not after it is completed, as the timing of the click is crucial. Click when your dog or other pet does something you like, beginning with something easy that the pet is likely to do on its own, such as sitting or coming toward you. Click once, and if you want to express special enthusiasm, increase the number of treats, not the number of clicks. Don't wait for the whole picture or the perfect behavior, click and treat for small movements in the right direction. You want the dog to sit, and it starts to crouch in back: click. You want it to come when called, and it takes a few steps your way: click. Fix undesirable behavior by clicking desirable behavior, such as clicking the puppy for relieving itself in the proper spot. Click for voluntary movements toward your goal, and don't push, pull, or hold the animal, letting it discover how to do the behavior on its own.
