Puppy preschool or kindergarten is a great avenue for socialization with other puppies of an identical time. However, the conflict arises from the question of doggie vaccinations "is it safe to have a puppy out during this time?" This is a issue because on the main one hand you want to teach your pup to be sociable but keep carefully the puppy safe at exactly the same time.
Ask any visitor that comes to visit to take care of the puppy all over; coming in contact with the paws and feeling in between the toes; playing with the ears; offering restrained hugs; using the mouth area and starting the mouth putting your finger on the puppy's tongue. If at all possible expose your pup to children and instruct them the way to handle the puppy dog properly. Constantly be sure when children and young puppies are playing alongside one another that they are supervised. You don't want the children to experiment with too around with the doggie and you do not want the puppy dog getting so hyped up by antics of children and becomes out of control.
