I suggest you get the books The Other End of the Leash by Patricia McConnell and/or The Culture Clash by Jean Donaldson(I think). Also The Power of Positive Dog Training by Pat Miller would be helpful. These three books are the core of my dog training philosophy. There are many other books but these are the core.
I own all three of those, and I would wager about half or more of our regular members have read them as well.
You assume a lot.
