Many methods for dog training exist, including using a dog clicker, classical
conditioning, positive reinforcement and the Premack principle. Although you may not
have heard of the Premack principle, you might already be using it with your dog and
even your children.
Developed in 1965 by David Premack, who was an Emeritus Professor of psychology at
the University of Pennsylvania, the Premack principle works on both humans and dogs.
