Puppy Socialization 101

You've got a new puppy and you are looking forward to many happy years of bringing your dog with you nearly everywhere - the dog park, long hikes, friends' houses, road trips, campsites, your neighborhood, maybe even the local cafe where he can loll at your feet and thump his tail charmingly at all who pass by, inviting pats on the head and belly rubs. You envision your dog as an ambassador for his species, a friendly and relaxed diplomat able to charm your friends, other canines at the dog park, children and maybe even - gasp! - cats (perhaps there is hope for world peace, after all).
