The first period of a puppy prospect's life is normally spent in socialization rather than formal training. Large formal organisations often use puppy foster parents during the pups first year and the pup grows up in a normal family environment surrounded by the sights, sounds and smells of the type of environment they will later work in, learning to be clean and toilet trained, confident and happy.[7][8] Owner Trainers raise their pups themselves, so the dog lives with the same person who will later be their handler, but will also focus on giving the puppy confidence, play experiences and socialisation in the environments they will later work in.
