The pups are now being exposed to a new environment outside of their whelping box. These are some pictures of them in our hallway where it's tiled. Following the Rule of 12 Socialization Guide, they have been exposed to several different surfaces already: fabric, carpet, tile. It's also amazing how much stronger their rears are after just 2 days. Only a couple of days ago they were pulling themselves along by their front legs & today they are taking many more steps on all fours.
