Ask any visitor that comes to visit to take care of the puppy around; touching the paws and feeling in between the toes; using the ears; supplying restrained hugs; playing with the mouth area and starting the mouth putting your finger on the puppy's tongue. If at all possible expose your puppy to children and show them the way to handle the doggy properly. Always make sure when children and young dogs are playing jointly they are supervised. You do not want the children to experiment with too approximately with the pup and you don't want the dog getting so hyped up by antics of children and becomes out of control.
A whole lot of puppy socialization can occur in the home environment - exposure to loud banging noises, such as clanging pans and pots, vacuum cleaners, washing machines, lawn mowers, etc.
