In troubled times, we all look to heroes to step up and lead us from a dark place to one of hope.

And in the wake of Hurricane Harvey, which battered and then flooded much of southeast Texas over the weekend, we didn't have to wait long.

Countless everyday Texans have risked their own lives to haul people and pets out of the affected areas.

But Otis may be the unlikeliest hero of all.

After all, he wasn't exactly leaping into the breach when Tiele Dockens snapped this picture over the weekend. Nor was the golden retriever hauling anyone out of danger.

Instead, Otis was carrying cargo that was precious mostly to him: a big bag of dog food. And he was just trying to get it home.

But there was something about that picture — a humble family pet clinging tightly to his one precious possession, despite the chaos all around.

A new survival icon emerges

Since Dockens posted the image on Facebook — a photo snapped while she was taking stock of the flood-wracked city of Sinton — the post has been shared more than 35,000 times.

"We are a population of about 6,000," Dockens told the Weather Channel. "We were out today clearing tree limbs from streets. Families are already starting to clean up. Our town is still out of water and power. I was driving around checking on family and friends' properties that decided to evacuate."

Then she spotted Otis.

"With his dog food of course," Dockens added.

It turned out, the man taking care of Otis, who belonged to his grandson, had been looking for the furry refugee who had slipped out of a screened-in back porch on Friday night.

"I kept yelling his name and yelling his name and he wasn't around," Segovia told the Houston Chronicle.

Amid devastating floods, with countless family pets already missing, the situation could have taken a dark turn. But not long after he was photographed high-tailing it down a city street, Otis found his way back home.

And, along the way, into the hearts of millions.

Sure, images of ordinary people doing extraordinary things can be a powerful cure for despair. And right now, Texas needs all the heroes it can get.

But sometimes, we need a simple reminder from our four-legged friends that they are in this mess, too. They're trying to get by one way or another. And if that happens to involve looting — err, retrieving — a bag of food, then this is a survivor's tale worth cheering for.
