Puppies generally stand by day 15 and take their first wobbly walk by day 21. By age three weeks, puppy development advances from the neonatal period to the transitional period. This is a time of rapid physical and sensory development, during which the puppies go from total dependence on Mom to a bit of independence.
Puppies are not born naked. Their skin is covered by a short, soft, and sometimes wooly-like hair. Sometimes the puppy hair, or fur as it is sometimes referred to, is a similar color to what is expected as an adult. Sometimes the puppy fur is slightly lighter when first born.
