Birth to Two Weeks From birth, puppies are able to use their sense of smell and touch, which helps them root about the nest to find their mother's scent-marked breasts. The first milk the mother produces, called colostrum, is rich in antibodies that provide passive immunity and help protect the babies from disease during these early weeks of life.
For the first two weeks of life, puppies sleep nearly 90 percent of the time, spending their awake time nursing. All their energy is funneled into growing, and birth weight doubles the first week. Newborns aren't able to support their weight, and crawl about with paddling motions of their front legs. The limited locomotion provides the exercise that develops muscles and coordination, and soon the puppies are crawling over and around each other and their mother.
Week Two-to-Four The second week of life brings great changes for the puppy. Ears and eyes sealed since birth begin to open during this period, ears at about two weeks and eyelids between ten to 16 days. This gives the furry babies a new sense of their world. They learn what their mother and other dogs look and sound like, and begin to expand their own vocabulary from grunts and mews to yelps, whines and barks. Puppies generally stand by day 15 and take their first wobbly walk by day 21.
For the first three weeks of life, a puppy is almost devoid of senses. Its eyes, ears and nose don't begin to work properly until the third week.

A puppy should remain with its litter mates till it is at least seven or eight weeks old
