Puppyhood is mysterious, exciting, challenging, curious, and full of transitions. Puppies are busy developing physical, cognitive, and social skills, which follow a very general timeline. If this sounds familiar, it’s not so different from the timelines and transitions we recognize in human babies and toddlers. And, as with children, understanding what happens and when helps us know what to expect and what puppies need from us in order to grow into happy, healthy, and well-adjusted adult dogs.
