A 5-year-old boy from Prescott, Wis., who'd been missing for 20 hours, was found a half-mile from his home by a four-legged volunteer — an 8-year-old Golden Retriever named Autumn.

According to WCCO, when Scott Meyer disappeared from his parents home last Tuesday on a sweltering hot day, hundreds of volunteers showed up to search for the child, who has autism.

The boy’s furry rescuer almost didn't join the search because his owner, Melissa Moser, was reluctant about the idea at first, but her husband, Jason Moser, convinced her to let them go.

"We were over here as soon as we could," Moser told the Star Tribune. "There are so many bad places he could have gone. There's a train down there, the river."

Autumn, who isn't a trained rescue dog, found Scott under an evergreen tree on Wednesday morning. Despite being dehydrated, sunburned and covered in bug bites, Scott is expected to make a full recovery.
