The Great Dane is a German breed of domestic dog known for its large size.The record holder for the tallest dog ever is a Great Dane called Zeus (died September 2014; aged 5), who measured 111.8 cm (44.0 in) from paw to shoulder. The tallest living dog is another Dane named Freddy, measuring 103.5 cm (40.7 in). Their average lifespan is 6 to 8 years; however, some Great Danes have been known to reach 10 years of age or more. Like many larger breeds, Great Danes are at particular risk for hip dysplasia. Dilated cardiomyopathy  and many congenital heart diseases are also commonly found in the Great Dane, leading to its nickname: the heartbreak breed, in conjunction with its shorter lifespan. Great Danes also may carry the merle gene, which is part of the genetic makeup that creates the harlequin coloring.
