If you administer a physical correction for a particular unwanted behavior and it has no effect on the dog whatsoever, what should you do?

If a physical correction indicates punishment, this form of correction does not affect a dog because it is not likely that the dog will make a connection between its behavior and this type of correction. Positive reinforcement should be tried to correct the dog's behavior. Dogs respond very well to treats and will perform the desired behavior when taught that they will receive a food treat in response to appropriate behavior. In addition, most dogs respond to positive praise since they want to please their owners, so using terms like "good boy" to reinforce good behavior can be highly effective.

Basically create a schedule on what you need to study and stick with it
