Being a veterinarian, I had been called to examine a ten-year-old Irish Wolfhound named Belker. The dog's owners, Ron, his wife, Lisa, and their little boy, six-year-old Shane, were all very attached to Belker, and they were hoping for a miracle. After examining Belker, I found that he was dying of cancer. I told the family we couldn't do anything for Belker, and offered to perform the euthanasia procedure for the old dog in their home.

As we made the arrangements, Ron and Lisa told me that they thought it would be good for Shane to observe the procedure. They felt as though he might learn something from the experience.

The next day, I felt the familiar catch in my throat as Belker's family surrounded him. Shane seemed so calm, petting the old dog for the last time, and I wondered if he understood what was going on. Within a few minutes, Belker slipped peacefully away.

The little boy seemed to accept Belker's transition without any difficulty or confusion. We all sat together for a while after Belker's death, wondering aloud about the sad fact that animal lives are so much shorter than human lives. Shane, who had been listening quietly, piped up and said, "I know why."

Startled, we all turned toward him. What came out of his mouth next stunned me. I'd never heard a more comforting explanation. He said, "People are born so that they can learn how to live a good life -- like loving everybody all the time and being nice, right?"

The six-year-old continued, "Well, dogs already know how to do that, so they don't have to stay as long."
