Welcome to e-Bedience. I've been answering people's questions in Blunderchat about dog training for many months, and Pat suggested that it would be a good idea to get the information into a spot where more people could access it at their convenience. No single book or method is ever entirely wrong or entirely correct.
Different methods work for different breeds and for different dogs and for different handlers.
The suggestions that I will make have worked for me, or for people with whom I have worked. Never, ever do anything that you feel may put you in danger of being bitten. Never, ever do anything that you feel will harm or injure your dog. If you aren't very sure about what the suggestion says, don't try it. Please keep in mind that I'm trying to do this without ever having actually seen you, your dog, and most importantly, how you interact.
