Here's what a an expert from the American Veterinary Society of Animal Behavior had to say about socializing puppies.
Because the first three months are the period when sociability outweighs fear, this is the primary window of opportunity for puppies to adapt to new people, animals, and experiences.
Incomplete or improper socialization during this important time can increase the risk of behavioral problems later in life including fear, avoidance, and/or aggression.
There are other benefits of Puppy Socialization sessions too.
Play sessions and play-fighting teach puppies to be gentle with their mouthing and biting. This will help your puppy learn to bite other dogs and toys, rather than you.
Owners can drop off their puppies and get some separation anxiety practice too. Separation anxiety can be a big issue with puppies and this helps get them used to being in a new environment without their owner. If you want to see how your puppy's session is going, you can always watch live via a free streaming service.
