Dog awakens Dad late at night after spotting danger in the walls.

After defending his new owner from a hidden threat in the walls, a dog in San Diego is being hailed as a hero. The father will never forget when Carl the Wonder Pup informed him that something was wrong.

Carl attracted Drew Smith’s attention while he was browsing the shelter for a Golden Retriever. He was intended to adopt this dog in its place. The two got along right away, and for the first three weeks, Drew didn’t hear the amiable, laid-back dog bark.

Then, one night, Carl’s frenzied barking kept waking Drew up. He understood there must be a problem. It was discovered that the dog had already detected smoke in the walls before the smoke alarm had sounded. Carl saved his father shortly after his father had just saved him, and the home was on fire!
