Puppies are BABIES!!!! A stable social well bred dog should mature into a dog who - ESPECIALLY if well socialized - understands the difference between a friendly/neutral interaction and a threat!!! You do NOT want an overly suspicious, fear motivated dog!! Seriously - the better social nerves the dog has, the more likely he is to be able to discern a negative social interaction!
Let him be a baby now and work on his social and environmental stability.
