The tallest dog living (male) is 1.031 m (3 ft 4.5 in), and was achieved by Atlas and his owner Spencer Seay (USA) in Canton, Georgia, USA, on 3 April 2021.
Spencer decided to get Atlas, a Great Dane, officially measured after being told time and time again that the dog was the biggest anyone had ever seen.
