All Dog Breeds >>Health of Great Dane
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. Great Danes have some health problems that are common to large breeds, including gastric dilatation-volvulus (GDV) (a painful distending and twisting of the stomach). This is a critical condition that can affect Great Danes and other deep-chested breeds, and which may cause death if not quickly addressed. Drinking large amounts of fluid in a short period of time can provoke GDV in Great Danes, as well as other larger breeds of dogs.
It is a commonly recommended practice for Great Danes to have their stomachs tacked (Gastropexy) to the right abdominal wall if the dog or its relatives have a history of GDV, though some veterinary surgeons will not do the operation if the actual sickness has not occurred. Elevated food dishes are often believed to help prevent GDV by regulating the amount of air that is inhaled while eating, although one study suggests that they may increase the risk. Refraining from exercise or activity immediately before and after meals may also reduce risk, although this has not been validated with research.
Signs that GDV may have occurred include, but are not limited to, visible distension (enlargement of the abdomen) and repeated retching that resembles repetitive non-productive attempts to vomit. GDV is a condition that is distinct from another condition referred to as bloat; though, bloat may precede the development of GDV. GDV is a surgical emergency; immediate veterinary evaluation should be sought if a dog demonstrates signs of this condition. Breed clubs health surveys in the UK and US put the average life span of Great Danes at 6.5 to 7 years.
Dilated cardiomyopathy (DCM) and many congenital heart diseases are also commonly found in the Great Dane, leading to its nickname of the Heartbreak breed, in conjunction with its shorter lifespan. Great Danes also suffer from several genetic disorders that are specific to the breed. For example, if a Great Dane lacks color (is white) near its eyes or ears then that organ does not develop and usually the dog will be either blind, deaf, or both.
