German Shepherd Obedience Training

I just got a German Shepherd 8-week old pup, and im just so exicited. anyway i have a question about obedience
..training. I planning to attend classes as soon as possible because I heard that its best to train a dog when its very young. Any way if I were to take those classes, how many sessions does it take to complete the course, and how much does it usually cost??
I used to teach puppy kindergarten classes and it was so much fun! Look for a teacher who is experienced with Puppy Training–lots of socialization, play time, and gentle training with lots of praise and treats. A typical 6-8 week course can run around $10.00 a class on average. You may need to attend more advanced classes as he grows and learns. There is also a lot you can teach him now in the meantime–I strongly recommend Dr. Ian Dunbars book “AFTER YOU GET YOUR PUPPY”. It will teach you everything you need to know on puppy training. Dr. Dunbar is the one who first introduced puppy kindergarten to us over 25 years ago. His web site is http://www.siriuspup.com
