Hey I have a Cade too! (Although obviously spelled differently)
Although books on dog raising are similar to books are child-rearing...lots of different opinions and no 1 book is totally right. You have to pick and choose. My first piece of advice would be to immerse yourself and read everything, even if it doesn't pertain necessarily to foundation work. You want to know where you're going before you start the journey. It's not a recipe. Doing certain things does make you a Schutzhund dog. Training has to be tailored.
My second piece of advice is find a club. Can you do stuff at home? Sure you can. But you're really much better off working with people who know what they are doing. Schutzhund can be so subtle. It's not just about sitting, or platzing, or chasing, or biting. There's alot that has to do with HOW it's done. have raised 2 dogs and am on my third puppy, and have consistenly gone to training for almost 3 years. My dogs are doing well but I can tell you right now that this puppy has a HUGE advantage on my other 2 because of all I've learned. Not just from my previous dogs but from all the other dozens of dogs I ahve gotten to see being worked at club.
This website lists alot of different books that you can check out.
You might want to check out Leerburg. It was one of the first places I started reading when i got my dog because it has ALOT of information, of course you have to pick and choose what you like but some of it is very valuable.
Nate Harves has been writing articles for Schutzhund USA and he ahs some of them posted here. Maybe more advanced but it always good to learn more and be a sponge, so you can get an idea of where you might want to go.
Claudia Romard also write articles for the magazine. She has them posted here and some have to do with raising dogs. I really liked her when I saw her at a seminar.
