Here's somebody my Madison would stare in wonder at. This colossus is Giant George, the Guinness world's record holder as the largest dog on the face of the Earth. Judging from this picture, I think they may be right. George is a Great Dane that measures almost 43 inches from the bottom of his feet to the top of his shoulders. He weighs 245 pounds. That is one BIG dog. He lives in Tucson, Arizona, eats 110 pounds of food a month and sleeps in his own queen sized bed. As a dog walker, instead of walking George, I could saddle him up and ride him. He would take ME for a walk! Click HERE to see an article and some more pictures.
