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.
The third stage is passing of the placenta. The afterbirth might pass with each individual puppy, usually within 15 minutes of delivery. If the mother has a few puppies in rapid succession, those placentas may come out en masse. The final placenta should appear within half an hour of the last puppy's birth.
