The experiences your puppy has during its first 16 weeks of life will
greatly influence the sort of adult dog it grows into. It is important that your puppy interacts with other people, dogs and puppies during this time to help prevent it developing antisocial behaviour.
Puppy preschool is an ideal way to socialise puppies of this age because all the pups attending classes have started their vaccination program and the sessions ensures the puppies learn to play nicely. It is preferable to complete the four-week course by the time the puppy is 16 weeks old.
Toilet training involves frequent positive reinforcement rather than punishment. When the pup starts to sniff and circle, and always after eating, playing or sleeping, take the puppy outside to the area you want it to urinate and defecate and stay with it until it does. After the puppy uses his/her toilet, reward him/her with praise and a food treat.
Ignore mistakes because the puppy will not associate any punishment with the mess on the floor.
