A newborn pup is blind, deaf and toothless. The first two weeks, he depends totally on his mother for nourishment and care.  He also needs lots and lots of sleep. When the puppy is two to four weeks old, his eyes will open, his hearing and sense of smell develop and he begins to get teeth.  He will begin interacting with other puppies in the litter by learning to walk, bark and wag his tail. He’ll also begin to recognize you and other family members now. At about four weeks, the mother dog will start weaning her pups by showing impatience while they nurse.  This is the time to start the puppies on soft food and water. From four to six weeks he will learn to play so this is the time to get some dog toys for him. He’ll find out his rank in the pack and generally how to be a “real” dog.
