Camera Caught What This 155lb Great Dane Did Seconds Before the Carbon Monoxide Hit

#greatdane #gentlegiant #dogstory #rescuedog What makes a 155-pound Great Dane lose his mind on a freezing winter morning—and what does the home camera catch him doing four minutes before his family ever felt a thing? Gunner spent 502 days in a shelter while 24 families walked past the gentle giant everyone called "too much." Then one Navy wife, alone while her husband was deployed overseas, took a chance on him. Months later, that single decision is the only reason she and her baby girl survived an invisible, odorless poison creeping through their home. This is a story about the things dogs sense long before we can, and why the dog nobody wanted became a family's guardian. Watch until the end.
