The Third Week

During this week, the puppy’s other senses start to
operate.Their eyes are open now.They can detect light and dark, as well as movement,
and will respond to large or sudden sounds. They will start
to interact with his brothers and sisters, and he starts
developing social skills by this interaction, i.e.,
touching them with his paws and mouth.
They learns to crawl, and his tail begins to wag. They can also
venture from his mother to urinate on his own. In some
cases, puppies, though not weaned, can be fed liquid food
suggested by a veterinarian.
