All pups need to be gently exposed to lots of different sights, situations, experiences, people, sounds, etc. It's called socialization. The more socialized your pup is when he's 5 months old or younger, the better adjusted and less flighty/scaredy he'll be when he's all grown up. It's not hard to socialize a pup, it just takes some planning, some very good tasty food, and the willingness to leave if your pup's not having a good time.
Last week, Ike got to visit a federal building and rode on a freight elevator, saw some really strange looking staircases, and experienced a long, shiny hallway. He was unaffected by most of what he saw – watch the video below and take note of his waggy tail and happy demeanor.
