Yep its true you only have until 16 weeks to get them socailized so you are going to have 3 weeks to try to indroduce him to as many different situations and experiences as you can.
Lots of different types of people and children, allsorts of different dogs (big, small, fat, thin, young, old etc), travelling in the car, on buses, trains, going to the vets, walk him different places and let him sniff all the trees and run on the grass, make sure he experiences water. Just as much as you can possibly do with him, you'll be very busy!
The more things you get him used to the less likely he is to be yappy, badly behaved, agressive and or fearful.
