A whole lot of puppy socialization may appear in the house environment - exposure to loud banging sounds, such as clanging pots and pans, vacuum cleaners, washing machines, garden mowers, etc.
Ask any visitor that involves visit to take care of the puppy all over; coming in contact with the paws and sense in between the toes; using the ears; providing restrained hugs; playing with the oral cavity and beginning the mouth placing your finger on the puppy's tongue. If at all possible expose your puppy to children and show them the way to handle the doggie properly. Constantly be sure when children and puppies are playing jointly that they are supervised. You do not want the kids to learn too approximately with the puppy and you don't want the pup getting so hyped up by antics of children and becomes out of control.
