Puppies are usually weaned at six to seven weeks, but are still learning important skills as their mother gradually leaves them for longer periods of time. Ideally, puppies should stay with their littermates (or other “role-model” dogs) for at least 12 weeks.
Puppies separated from their littermates too early often fail to develop appropriate social skills, such as learning how to send and receive signals, what an “inhibited bite” (acceptable mouthing pressure) means, how far to go in play-wrestling, and so forth. Play is important for puppies because it increases their physical coordination, social skills, and learning limits. By interacting with their mother and littermates, puppies explore the ranking process (who’s in charge) and also learn how to be a dog.
Skills not acquired during the first eight weeks may be lost forever. While these stages are important and fairly consistent, a dog’s mind remains receptive to new experiences and lessons well beyond puppyhood. Most dogs are still puppies, in mind and body, through the first two years of life.
