I am not a big fan of clicker training. After a dog has learned a behavior, and given treats when the task is performed correctly, a clicking sound is made with a clicker along with the positive reinforcement, usually a treat. This is done repeatedly until the dog begins to associate the click with the correct behavior, reinforced with the pleasant biological, positive reinforce. The only problem I have with it is, what happens when the dog hears a similar click from someone or something else? I know people have had success with them, they are just not for me.
