<P> Puppies are born with a fully functional sense of smell but ca n't open their eyes . During their first two weeks , a puppy 's senses all develop rapidly . During this stage the nose is the primary sense organ used by puppies to find their mother 's teats , and to locate their littermates , if they become separated by a short distance . Puppies open their eyes about nine to eleven days following birth . At first , their retinas are poorly developed and their vision is poor . Puppies are not able to see as well as adult dogs . In addition , puppies ' ears remain sealed until about thirteen to seventeen days after birth , after which they respond more actively to sounds . Between two and four weeks old , puppies usually begin to growl , bite , wag their tails , and bark . </P>
