I highly recommend kikopup too. Her videos are a joy to watch, so it makes research a breeze. She's much better at training than most of us will ever be but you don't have to be perfect at it to get big results.
I joined this forum when I got my second dog and I wanted to learn. And I did learn so very, very much. It is worth doing some browsing and checking out some of the linked resources people recommend. I personally recommend the book "Chill out, Fido!" to everyone because it gives a great introduction to dog behaviour and training methods and the actual training exercises are explained in minute detail. Even if you don't do the exact same exercises (though they all sound very useful), they are a good demonstration of how dogs learn. Which I think is really very logical but not at all intuitive to most humans.
Training doesn't have to be a chore either. Especially if you keep thinking of the end goal. I was only thinking this morning how glad I am that I put in the effort and have such a very obedient dog. It makes life so much easier.
