Ask any visitor that involves visit to take care of the puppy around; coming in contact with the paws and sense among the toes; playing with the ears; providing restrained hugs; using the mouth area and starting the mouth placing your finger on the puppy's tongue. If at all possible expose your puppy to children and instruct them the way to handle the dog properly. Always make sure when children and pups are playing collectively they are supervised. You do not want the children to experience too about with the dog and you don't want the doggie getting so hyped up by antics of children and becomes uncontrollable.
Puppy preschool or kindergarten is a great avenue for socialization with other young puppies of a similar get older. However, the turmoil arises from the question of doggie vaccinations "could it be safe to take a puppy out during this time period?" This is a dilemma because on the one hands you want to teach your pup to be sociable but keep the puppy safe at exactly the same time.
A lot of puppy socialization can occur in the home environment - contact with loud banging noises, such as clanging pots and pans, vacuum cleaners, washers, lawn mowers, etc.
