As puppies become more mobile we offer different surfaces textures for them to walk on during handling time. Mobility also marks the beginning of elimination acclimation. Puppies also have a natural inclination to keep their nest/bed clean, and as they are able to stand and move out of bed they eliminate away from the bedding area, on their own without mom's help. This is the time to acclimate puppies to very early house training skills. For this litter I will be "litter training" the puppies, and later converting the litter to an outdoor area, helping them become used to going outside to eliminate. So we place bedding in half of the whelping box, and litter or paper in the other, thus providing distinct area for puppies to sleep verses eliminate.
Mobility also makes for difficult photo ops. Wiggly squirmy puppies are very hard to keep in focus! So I have grouped the females and males, but no individual photos this time. And finally you can start to see who will be darker.
