Puppies are teething and playing!

We are now at almost three weeks old and I am noticing rapid changes. Puppies are becoming more mobile which means it's almost time for the puppy pen. There are also tiny teeth popping through and they are either teething or learning to play by chewing on their litter mates. They are becoming more interactive with us and will all run over to where we are when we are near the whelping box. They are also becoming more interactive with each other and becoming more vocal with growls and barks and I even watched one howling this morning! What a sight! Their personalities are starting to develop and they are becoming so much fun! I just posted new pictures in the puppy gallery but here's one I just love.
