Great Danes' Health Issues
The Great Dane is one of the giant dog breeds of the world. Optimal breeding practices strive to produce physically healthy dogs with a sound temperament, but numerous hereditary diseases continue to affect this very old and powerful breed of dog. Danes typically have a life expectancy of 10 years, which is less than that for most smaller dog breeds. Some of the inherited diseases that affect the Dane are, unfortunately, life-threatening.

Hypothyroidism
-
Hypothyroidism is an inherited disease that is caused by an inactive thyroid gland. Danes suffering from hypothyroidism do not receive sufficient hormones from their thyroid gland, which affects their metabolism and immune system. This condition can be diagnosed by a blood test and is managed with thyroid replacement therapy, which must continue for the duration of the dog's life. Symptoms of hypothyroidism include susceptibility to infections and skin problems, such as hair loss and excessive shedding.
Bloat
-
Bloat is common in deep chested dog breeds and Danes are therefore predisposed to this painful and potentially life-threatening condition. The stomach of Danes suffering from bloat swells and typically rotates, thereby cutting off blood to the surrounding organs. Early warning signs of bloat include noticeable swelling of the animal's abdomen and rapid breathing. The dog experiences considerable pain and begins to salivate excessively. Danes suffering from bloat must receive immediate veterinary attention, as surgery is necessary in almost all cases. Great Dane owners can minimize the risk of bloat by elevating the dog's food dishes. Danes should also be offered small, but regular, meals throughout the day and must not be allowed to drink large amounts of water after exercising.

Hip Dysplasia
-
This is an inherited disease that afflicts a number of Danes. Hip dysplasia is not a fatal condition, but is both debilitating and painful. This condition is caused by an abnormality of the hip socket. The thighbone does not fit correctly into the hip socket and through normal use it continues to deteriorate, causing progressively more damage to the joint and surrounding tissue. Danes that suffer from hip dysplasia invariably exhibit an abnormal gait. These dogs may also become lame in the rear quarters and choose to move as little as possible. Hip dysplasia is correctly diagnosed through X-rays of the hip joint.
Dilated Cardiomyopathy
-
According to the Great Dane Club of America, heart disease is one of the most prevalent fatal conditions experienced in this breed. Dilated cardiomyopathy is an inherited, degenerative heart muscle disease. The condition involves an enlarged left ventricle, which results in the heart not being able to function optimally. Dilated cardiomyopathy is unfortunately a fatal disease.
