Happy or Sad?

Molly wags her tail when she sees me. I never know whether she is in pain or not. She has fallen down and never makes a sound. I have heard her bark once or twice. With an aging 'puppy', this is hard, because it is hard to tell when there is something wrong. Anyway, I have to keep my eye out for signs of anything. This makes me look like an over worried parent! And, I am. She is so, so, so precious and tender in her kisses. Just as long as there is no food involved.
