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.
This x-ray was taken the day before the puppies were born. You can see the one pup engaging in the birth canal. She is within 24 hours of delivery. X-ray showing three puppies. X-ray showing four puppies. If you x-ray at days 55/56/57 then you will be able to see heads, spines, ribs and legs. Count the heads first, and then find a spine to go with each head.
