except the blurb about waiting until the puppy is fully vaccinated to bring them into the real world. One of the worst things we can do is not expose our puppies to new things- IN A CONTROLLED ENVIRONMENT! Im not saying go to the dog park and let your puppy get exposed to god-knows-what or worse, get scared by another dog now creating a negative experience. But please do not avoid controlled situations like a trainer monitored puppy class. Ask their cleaning policy before you go if you have doubts. We are creating a world of fearful, under socialized dogs by keeping them in our homes until the period when are excepting of new things more easily (18 weeks and under) goes by.
More information from a well regarded veterinarian including a study on the percentage rate your puppy could get sick vs the effects of under socializing:
