#10 Giant George: A 43-Inch-Tall Great Dane (Arizona)

Giant George, a 43-inch-tall Great Dane from Tucson, Arizona, held two world records: the tallest living dog and the tallest dog ever (until February 15, 2010).

George has made appearances on The Oprah Winfrey Show & Live with Regis & Kelly. However, that’s not all; Giant George has developed quite a fan base, so his owner keeps fans up to date with the dog’s activities via his website and YouTube channel.

As incredible as it seems, this pet also has a book, “Giant George: Life with the World’s Biggest Dog,” and a Twitter account, of course.

Unfortunately, George passed away on October 17, 2013, one month away from his eighth birthday.
