TUCSON, Ariz. -- A 250-pound blue Great Dane from Arizona gives new meaning to the term "big dog."
Guinness World Records says Giant George from Tucson is the tallest dog ever on record.
The 4-year-old Titan took the title of world's tallest dog in 2009 after Gibson, a Great Dane from Grass Valley, Calif., died of bone cancer.
Guinness officials say there were conflicting reports about Giant George's height, so they sent a judge to verify it.
The 4-year-old is owned by David Nasser.
