A dog in San Diego is being hailed a hero after rescuing his new owner from a hidden danger in the walls. Carl the Wonder Pup knew something was wrong and informed his father, and the man will never forget it.

Drew Smith was at the shelter searching for a Golden Retriever when Carl captured his eye. This was the dog he was supposed to adopt instead. Both hit it off immediately, and Drew didn’t hear a bark from the friendly, easy-going dog for the first three weeks.

And after that one evening, Drew was awoken by Carl’s continuous, frantic barking. He knew something should be wrong. It turned out the dog could sense smoke in the walls even before the smoke alarm went off. The house got on fire, and Carl rescued his dad simply soon after his father saved him!.
