We all know by now that positive reinforcement training is about immediacy, consistency, and reward. Clicker training can help you mark a specific behaviour instantly and deliver the reward accordingly.
Rather than focusing on what your dog may be doing wrong and perhaps taking good behaviour for granted, clicker training helps you, the owner, to focus on what your dog is doing right.
By encouraging the good stuff rather than telling your dog what not to do, you can have an amazing effect on how your dog chooses to behave.
