I knew it as soon as I walked out on to the porch last Sunday night. Our 12-year-old yellow lab, Fisher, was struggling to breathe, could not stand up, and would not eat or drink. I looked at Darren and said "I think it's time," as my voice began to break. Just the day before he seemed fine, but we had known for a while as we watched him age that his time was coming. We just didn't know it would be this day, this sudden.
