Always remember that a puppy has a very short memory span. Make sure you praise and discipline in the moment that your puppy does something that is praiseworthy or requires discipline. Even as your dog gets older discipline and praise should happen in the moment. It will be much more effective if your puppy receives an immediate consequence rather than a lengthy punishment for an infraction that they can't remember committing.
Most people get a puppy between 8-10 weeks old. This is an important time in your puppy's development because they have begun to shift their focus from the mom to their litter mates and people. The puppies are exploring their independence and the outside world more. You'll really want to make sure that your puppy's breeder is exposing them to different people, sounds and environments before they come to your home. This will help your puppy adjust to you and the different situations that could arise in your home; i.e. children, visitors, etc.
