A 76-year-old Australian man was trapped under his car for four days before help arrived. Throughout the ordeal, his loyal dog Boydy never left his side.

Australia's Daily Telegraph reports that Herbert Schutz crashed his car on his property after hitting a tree. Police believe Shutz got out of the car, which then partially rolled on top of him, trapping him underneath. Pinned under the car, Schutz wasn't alone. Boydy, his Australian kelpie, kept him warm by lying across his chest at night.

Authorities were reportedly stunned that Schutz was in such good health considering he'd gone without food, water or shelter. Schutz gave credit to Boydy, according to Eric Merritt, a neighbor who saw the wreck and came to investigate.

"I saw the car but he wasn't in it ... then I heard him call out to his dog," Merritt told NBN News. "I thought to myself 'Where the hell is he?' ... I walked around the car and there he was on the ground beside it." Schutz told Merrit that his dog had saved him. "He said his dog lay on him and kept him warm a lot of the time."

"Even when we found him, the dog ran straight to his side and cuddled up to him. He didn't want to leave him even then," Merritt said.

Schutz suffered serious injuries, including a fractured skull, two broken hips and a dislocated shoulder, according to the Newcastle Herald. His daughter Heika told the Daily Telegraph that her father is now on the mend. "He is in very good care and is conscious and lucid at the moment, which is amazing given what he has been through," she said.

Boydy is being cared for by neighbors until Schutz returns home.
