It's worriesome indeed, but I feel as if that's why most people don't recommend socializing until after your puppy has their parvo vaccination and to keep the puppy with the mom for 8 weeks. As I imagine a puppy isn't going to pick up parvo from their mother or father. My puppy got his first vaccination when he was five weeks old, and will be getting his parvo as well as others around 8 weeks. Thus giving plenty of time within the puppy socialization window to be introduced to new dogs and new things.
