Clicker Training. Clicker training is a method that uses a unique sound, a click, to tell a dog that he has done something right. Because the click sound is hard to replicate in daily life it is a distinct sound that can be used to mark any action or behavior a dog does. The sound is made using a 'clicker'.
A clicker is not necessary but it's easier to teach bird tricks because it tells the bird that it done the right thing. 1  Pets & Animals.
