For pups that are smaller and 4 days younger, you wouldn't know. Most times you find them on top when playing.
They are really a fun bunch and they are hopping and jumping over to get to one point to the other. They are really used to the hallway now so soon - today - early evening we will take them upstairs in the hall to play with all sorts of new toys. We will see how they do there.
How can it be that they are growing up...
