Professional tennis player Jannik Sinner is known for his precision, composure, and strength on the court. But off the court, a recent encounter has captured the hearts of fans around the world—not for his tennis, but for a simple act of kindness that unfolded on the streets of Rome.

It began like any other day. Sinner, currently training in Rome ahead of the summer tennis circuit, was out for an early morning jog through a quiet neighborhood park. As he picked up his pace along a winding path, he noticed a small, scruffy stray puppy trailing behind him.
“At first, I thought it was just a coincidence,” Sinner said in a short interview. “But after a few minutes, I looked back and saw the little guy still running after me, his tail wagging like crazy.”
The puppy, believed to be around three months old, was visibly malnourished and dirty. Still, he didn’t seem afraid. In fact, he appeared determined to stay close to the athlete, despite being unable to keep up with his speed.
“I stopped and kneeled down, and he ran straight into my arms,” Sinner recalled. “He had this look in his eyes… like he was asking for a second chance.”
Moved, Sinner sat down with the dog for a while, gave him water from his bottle, and eventually resumed his jog, assuming the dog would eventually wander off. But to his surprise, the puppy stayed.
“I had to go back to the training center, so I left him near the entrance of the park. I looked back a couple of times. He was just sitting there, watching.”
A Loyal Friend Waiting
The next day, Sinner returned to the same spot—and there he was. The puppy, covered in dirt and curled up beneath a bench, had waited overnight.
“That moment broke me,” Sinner admitted. “I knew then that I couldn’t just leave him there again.”
Sinner took the pup to a local veterinarian for a full check-up. Apart from being underweight and suffering from fleas, the dog was otherwise healthy. No microchip was found, and no one had reported a missing pet matching his description.
What came next was perhaps the most heartwarming twist of all: Jannik Sinner adopted the puppy.
A New Life Begins
Naming the dog “Fede” — short for “fedele,” which means “faithful” in Italian — Sinner brought him home and introduced him to his life off the court.
“He follows me everywhere now,” he said with a laugh. “Even to training, when it’s allowed.”
Fede has quickly become a fan favorite, appearing in Sinner’s Instagram stories and even getting his own little dog bed in the tennis locker room.
Fans were quick to share their reactions.
“This is the most beautiful story I’ve read in a long time,” one user wrote.
“Jannik didn’t just win on the court. He won our hearts,” said another.
A Message of Compassion
The story has gone viral on Italian and international sports media, not just because of its feel-good nature, but because of the genuine humanity shown by one of tennis’ rising stars.
Animal rescue organizations have praised Sinner for his example, encouraging people to consider adoption over purchasing pets.
“Jannik’s story reminds us that sometimes, animals choose us. And when they do, it’s a bond that goes beyond words,” said Laura Bianchi, spokesperson for Cuori Pelosi, a local dog rescue nonprofit.
Sinner, who is preparing for a demanding summer season, says the puppy has brought him peace and balance.
“There’s something about coming home and being greeted by pure joy. It helps me stay grounded,” he said.
More Than Just a Pet
While Fede may never understand the fame or headlines his new human brings with him, he certainly seems to know he’s loved—and that he found exactly who he was looking for when he ran after a jogger one morning in Rome.
“It started as just another run,” Sinner reflected. “But it ended with me gaining a friend for life.”
