Training (puppy training)(ie Operant Conditioning) should begin the day you bring your pup home.
Evan Graham (of Smartwork fame) has a DVD dedicated to training the "meat dog"
Go to his website at
www.rushcreekpress.com/ and click on "Books and DVDs"
then scroll down toward the end and you'll see "Gundog Essentials - Basic gundog"
that's the one you need.
I would however suggest the "Puppy" video to start out with.
