Take him out now—I carried mine around everywhere in one of those puppy pouch things I got from petplanet from about the age of 8 weeks. We did shopping areas, the park, train, you name it he came too so that by the time he was raring to be put down he wasn't scared of anything. Its fun carrying them everywhere as you won't get far because someone will always want to give him a cuddle and its a good way to get used different people.
Good luck—while they're not as mad as labs they make up for it in being very wilful, but its fun trying to outmanoeuvre them!
