Chicago, Illinois - Edmon Lighthall from Chicago has experienced the impossible! After ten years of uncertainty, his missing dog named Peter was finally found.

The four-legged friend disappeared from the family's backyard without a trace in 2015, but the 51-year-old never gave up hope.

"I just felt deeply, a lot, for a long time, that we were inseparable in some way, and somehow this worked out," he told ABC News.

Then, on September 22, he got the incredible news: an animal chip company contacted him by text message to let him know that Peter's microchip had been scanned!

The dog was found on a road in Hammond, about 45 minutes away.

The next day, Ed drove straight out – and when he saw Peter, it was clear that his old friend had not forgotten him.

"It was absolutely unbelievable. I saw Pete. He came out, he greeted me, and it was almost immediate. I felt like he recognized me immediately," Ed recalled.

He later shared the moment in a TikTok video, which has since gone viral.

The returned family member is now about 14 or 15 years old, a little slower, but still the same happy guy!

To celebrate the incredible reunion, a "welcome home party" was organized in the park with family and friends.

"We went to the park, we did a picnic, we introduced him to his sister [dog] and a couple of other pooches from different family and friends," Ed said. "It was just a great experience."
