Practice running around in your underwear through your flower gardens at midnight trying to track down a brown dog in brown dirt in the dark who doesn't want to come back in.
I would also recommend a book called The Dog Listener.

Cesar is great but his theories are general in nature get pretty repetitive once you grasp his methods. In our case, his books and show did not address the issues we had with our dog because of our situation.
For example, Cesar would say that you need to eat before the dog does. Fine, I understand that the pack leader eats first. In practice though, I never eat breakfast and we eat supper kind of late. Our dog eats at 6 and 6. Am I expected to change my eating habits for my dog?
The dog listener says to make the dog sit while you pour food in its bowl and place the bowl on the counter. Either have a plate of crackers or pretend to snack on the dogs food out of the bowl while looking at him/her.
The difference in behavior after we started this is unbelievable.
The book is filled with great tips like this for people that have actual jobs and lives outside working at a dog rehabilitation centre.
