Yesterday Katie was a puppy, wearing her cone, the result of being spade last week, if not happily at least enthusiasticaly, and racing around the house.  This morning as she sleeps by my feet I glance down and realize she is the same size as Bonnie, our previous sheltie.  Katie was six months old last Friday.  Does this mean she is all grown up?  How did this happen between yesterday and today?   Should I mourn the puppy stage?  Probably not as she is still chewing and racing around and acting like a crazy dog when she is awake.  Last night I couldn’t contain her energy and finally put her to bed at 9:30 because I was exhausted.  I expect several more days or weeks of similar activity.  That makes me smile amid my tiredness!
