A horse who vanished eight years ago after running off with a pack of wild mustangs in Utah has now miraculously been reunited with his owner.

Shane Adams had given up hope he would ever see his beloved horse Mongo again after the stallion made a run for it while they were camping in the state’s West Desert all those years ago.

But his luck changed last month when Bureau of Land Management agents were rounding up a herd of mustangs — and realized one of the horses had the same brand that Adams had flagged when he first reported Mongo missing.

“I was overjoyed. I couldn’t believe it. It was like a dream come true,” Adams told The Washington Post of Mongo’s return home.

Eight years earlier, Mongo had been tied up outside Adams’ tent when the herd of mustangs suddenly ran by.

Adams recalled scrambling out of the tent half-dressed and trying to chase Mongo as he followed his newfound friends.

The heartbroken owner said he alerted the Bureau of Land Management and returned to the same area every weekend for three years in the hope that Mongo would be there.

When agents were rounding up the herd of wild horses, Adams said they started inspecting Mongo closely after noticing he fell into line quickly and showed signs of prior training.

The now-18-year-old horse was eventually brought back to Adams’ property last week.

“He was his calm, mellow and normal self — like he had never left at all,” Adams said, adding the horse was a few hundred pounds underweight after spending years running in the wild.

“There’s not a lot of food out there with this drought, and the horses look like walking death because they’re so skinny,” he said.

“I get why Mongo ran off — horses are tribal animals and will follow each other. But I’m happy we can take care of him now and make sure he eats enough food.”
