I just found this very good website on puppy socialization. It has valuable tips for breeders and puppy owners.

While I know that there is some disagreement in what the proper age is to send a puppy to his new owner, I know we all agree that a puppy should never leave before 8 weeks of age and that is what most of the experts say. Puppies should never be shipped before 12 weeks of age. Breeders that are raising the puppies should take all necessary steps to make sure the pups are properly socialized while they are in their care.
