I had to say goodbye to my heeler last month. I was lucky enough to spend 15 years with him. It sure is tough, and still makes my heart heavy. Your description of Molly reminds me of mine. We get to feel the sadness. That's part of the human experience. I sure hope someone is sad when my time here is over. Just make sure to remember the good times. I know there are many. They are never really gone as long as you remember them.
