How social is your dog?  Different dogs will want more or less social engagement.  But what is most important is that we teach our dogs how to cope with the lifestyle we bring them into.  Socialization is not just about giving your dog play time with others.  It's about exposing them to a variety of sights, sounds, and experiences in a safe and enjoyable way.  To have a dog that is comfortable and happy in different social situations, you have to take them with you, teach them kindly, and never overwhelm them.
