Puppy preschool or kindergarten is a great avenue for socialization with other pups of a similar age. However, the turmoil comes from the question of doggy vaccinations "could it be safe to have a puppy out during this time?" This is a problem because on the main one palm you want to teach your puppy to be sociable but keep carefully the puppy safe at exactly the same time.
Ask any visitor that involves visit to handle the puppy around; coming in contact with the paws and sense in between the toes; playing with the ears; supplying restrained hugs; playing with the mouth and opening the mouth positioning your finger on the puppy's tongue. If at all possible expose your puppy to children and coach them the way to handle the puppy properly. Constantly be sure when children and pet dogs are playing along they are supervised. You do not want the kids to play too approximately with the puppy and you don't want the puppy getting so hyped up by antics of children and becomes uncontrollable.
