The puppies eyes are open fully, they are reacting to sound, and beginning to investigate everything around them. We added some toys to the whelping box for visual interest and they are attracted to them, trying to grab them with their mouths and rubbing their faces against them. While they are still wobbly on their feet, they appear more deliberate and determined in their movements. These facial shots show the pigment appearing around their nose and mouth. Each puppy continues to grow at an astonishing rate, all have more than tripled their weight since birth.
