Some of my favorite dog-training, puppy-raising expert authors are:
Dr. Sophia Yin, Patricia McConnell, Pat Miller, Susan Garrett, Jan Fennell, Dr. Karen Overall, Cesar Millan, Karen Pryor, and Leslie McDevitt. My favorite groups/pages are Puppy Culture, Avidog and the Vermont Dog Pack (they also run "My Dog Camp" courses).
I recommend reading anything they have written (except for The Education of Will, by Patricia McConnell -- you might like it but I did NOT), watching YouTube videos, DVD's, etc. While you will want to take your puppy to a class or two, it's also good to educate yourself as much as possible.
Below are some suggested reads. Perfect Puppy in 7 Days is much cheaper HERE than on Amazon.
