Here's some useful info on how to socialize your new pup. Be careful of the health aspects of socializing though. I was advised to not let my pup come into a lot of close contact with the germy hands of people for the first few months of the pup's life. Their immune systems are more fragile when they are this young and can't handle every germ/bacteria out there until they're older.
