Zeus, a kind of Great Dane, was named the world's tallest dog by the Guinness World Records in 2011.
The tallest dog ever is Zeus (USA), a Great Dane who measured 1.118 m (44 in) tall on 4 October 2011 and was owned by Denise Doorlag and her family, of Otsego, Michigan, USA. Zeus weighed 70.30 kg (155 lb) and ate approximately 13.6 kg (30 lb) of food every two weeks.
When deciding the name, Denise wanted a big name for a big dog, whereas her husband wanted to call him a cute little name. When standing, Zeus reached an astonishing 2.23 m (7 ft 4 in) tall!
Despite his height, Zeus had a very laid back personality, he got along well with any human or animal and was very gentle, he was a certified therapy dog that visited people at a nearby hospital.
Due to his impressive height, he was able to drink straight from the tap. Sadly, Zeus passed away in September 2014 at the age of five.
