The Great Dane, also denoted as Grand Danois, is a German breed of domestic dog (Canis lupus familiaris) known for its giant size. The name of the breed in Germany is Deutsche Dogge (German Mastiff). They are known for their enormous bodies and great height. The Great Dane is one of the world's tallest dog breeds; the current world record holder, measuring 112 cm (44 in) from paw to shoulder, is "Zeus".
Their large size belies their friendly nature, with Great Danes known for seeking physical affection with their owners. The Great Dane combines, in its regal appearance, dignity, strength and elegance with great size and a powerful, well-formed, smoothly muscled body. It is one of the giant working breeds, but is unique in that its general conformation must be so well balanced that it never appears clumsy, and shall move with a long reach and powerful drive.
The Great Dane is a short haired breed with a strong galloping figure. In the ratio between length and height, the Great Dane should be square. The male dog should not be less than 30 in (76 cm) at the shoulders, a female 28 in (71 cm). Danes under minimum height are disqualified. From year to year, the tallest living dog is typically a Great Dane.
Like most dogs, Great Danes require daily walks to maintain their health. However, it is important not to over exercise this breed, particularly when young. Great Dane puppies grow very large, very fast, which puts them at risk of joint and bone problems. Because of a puppy's natural energy, Dane owners often take steps to minimize activity while the dog is still growing.
Given their large size, Great Danes continue to grow (mostly gaining weight) longer than most dogs. Even at one year of age a Great Dane will continue to grow for several more months. Great Danes, like most giant dogs, have a fairly slow metabolism. This results in less energy and less food consumption per pound of dog than in small breeds. The average life span of Great Danes is 6 to 8 years. Like many larger breeds, Great Danes are at particular risk for hip dysplasia.
