I ran across this site the other day that has some amazing information on it.
Chinaroad Lowchens of Australia
And this one is another good one:
Canine Reproduction Video and Book on Breeding and Whelping dogs by Debbie Jensen for dog breeders and Whelping Supplies needed to deliver puppies.
Just keep asking questions. Find someone near you that can mentor you. If nobody is near you, there's lots of us here that can offer help and advice as well.
Good luck!
