For most of his life, Messi — an 8-year-old Labrador retriever — has been a proud and dedicated member of the Transportation Security Administration (TSA). Stationed at Ronald Reagan Washington National Airport, his days were spent doing what he did best: using his remarkable nose to screen luggage for explosives and help keep travelers safe.

From his very first day on the job, it was clear Messi was born for this work. He thrived in the airport environment, greeting each shift with enthusiasm and focus. His handler, Peter, was always by his side, guiding him through countless searches. And while Messi took his responsibilities seriously, he also had simple joys: watching planes take off and land, running in the grass at nearby Gravelly Point, and, of course, playing with tennis balls after a job well done.

But earlier this year, after years of service, Messi reached a milestone — it was time for retirement. His TSA teammates weren’t about to let his last day pass quietly. They planned a special celebration, one that would let their four-legged colleague know just how much he was loved and appreciated.

On his final shift, Messi entered a large training room with Peter, just as he had many times before. A scent-training device was hidden somewhere inside, and Messi quickly got to work, his tail wagging as he sniffed and searched. When he located the device, the room suddenly came to life — dozens of tennis balls rained down around him, tossed from every direction by fellow canine handlers.

Messi’s reaction was pure joy. He jumped and spun in the air, scooping up balls in his mouth, chasing after others that bounced across the floor. The room filled with laughter, cheers, and even bubbles floating through the air to add to the festive chaos. It was the perfect farewell for a dog whose reward had always been a tennis ball and a pat on the head.

Then came the moment that truly marked the end of an era. Peter knelt down and removed the “Do Not Pet” patch from Messi’s harness — a quiet but deeply symbolic gesture. In that instant, Messi was no longer a working canine; he was simply a dog ready to enjoy his well-earned retirement. Hands immediately reached out to scratch behind his ears and rub his back, and Messi happily soaked up every bit of affection.

That evening, Messi went home with Peter, where a new chapter awaited. Instead of long shifts and focused searches, his days will now be filled with naps on the couch, leisurely walks, and as many tennis balls as he wants. His colleagues will miss him dearly, but they’re comforted knowing that their loyal partner is now free to live out his golden years in comfort and love.

Messi may have left the airport, but his years of service — and the joy he brought to those who worked alongside him — will never be forgotten.
