It's sad to see a dog grow old. I remember him when he was a young, frisky, misbehaving, and uncatchable blaze of fur. Eventually we channeled all that energy into agility training, and for a time, he was the poster pup for many local dog shows. Now he's droopy and limp. But he still comes when I call. I only wish I could have brought him with me after I got married, and we might still have had plenty of morning walks together.
