I met Edge while covering Seoul National University.

In a kennel off to the side of the veterinary hospital, an old Labrador sat alone. Eleven years old — 65 in human years. Six years as a narcotics detection dog, four as a blood donor dog. The fur around his mouth had gone white. The attending vet said: "If he doesn't find an adopter this month, he's scheduled for euthanasia."

I stopped for a moment.

A dog who'd spent his whole life serving the country, serving other dogs — to be put down if he couldn't find a home. That story hit directly.


I thought about how to write it.

I could write an explainer on blood donor dogs. I'd have statistics, expert comments, institutional context. But written that way, no one would read it to the end. Institutional articles don't move readers. Something different was needed.

I decided to write it in Edge's first person. Edge telling his own story. Starting from his first training at Incheon Airport, through his peak years finding eight drug cases, through four years in the hospital kennel. At the end, a postscript:

"If no one comes to take me home, I may have to face euthanasia."

The day the article ran, the phones at Seoul National University veterinary hospital didn't stop.


Adoption applications exceeded a hundred. An elementary school student sent a letter with 50,000 won cash enclosed: "Buy Edge what he needs." A former member of the National Assembly applied. A diplomatic official at the New York Consulate emailed. An animal protection organization in California made contact.

Edge was adopted by the Son family in Chungcheong. The family, who had been living in an apartment, moved to a standalone house for Edge's sake. Ten days later, when I visited again, Edge was running in a wide yard with younger dogs.

I had never received a response like this after writing an article.


SBS Animal Farm reached out. They broadcast Edge's story — nationwide awareness of blood donor dogs.

Later, a children's book called Blood Donor Dog Edge was published. The publisher asked me to write the foreword. I did, happily.

In 2019, Hyundai Motor launched a nationwide pet blood donation vehicle campaign. A billion and a half won custom blood donation car, dogs receiving the title "DOgNOR" along with scarves and vests. The blood donor dog system that had zero applicants and faced euthanasia in 2012 became a major corporate CSR program seven years later.

Sometimes the chain of causation from a single article takes this long to confirm.


One thought stays with me from Edge's story.

The same facts told from different voices produce entirely different articles. The blood donor dog system article could have been written dozens of times. But the article where Edge spoke directly existed only once.

What moves readers is not data or expert commentary but the story of one being right in front of you. Edge was the one who taught me that.
