10 day old puppies having a feast.......
Remember to turn sound on: Bigger puppies with bigger action on the nipples. Note the pumping and pulling action. The puppy in front of picture is moving her head around using the sense of smell to locate nipple for sucking on. Puppies are still deaf/blind using their sense of smell to locate Mom, a food source.
