Tucson lost one of its big dogs Thursday. Its biggest, in fact.

George, a Tucson Great Dane who was once crowned the Guinness World Records World’s Tallest Dog, died at age 7, a month before his eighth birthday.

George, who measured 43 inches from foot to shoulder, reigned as the record holder from February 2010 to September 2012, when he was overtaken by Zeus, a 44-inch-tall Great Dane from Otsego, Mich.

George was the star of a popular book co-written by his owner, real estate agent Dave Nasser, and made the rounds on national talk shows. His Facebook page racked up nearly 200,000 likes.

“George passed away peacefully surrounded by loved ones, one month before his eighth birthday,” a George handler wrote on his Facebook page.

“We appreciate the love and support you have given Giant George over the last several years. We look forward to honoring his spirit by continuing his charitable works.”
