A 2024 UK study found a life expectancy of 10.2 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds. [8] Health concerns within the breed include hip and elbow dysplasia, progressive retinal atrophy, bloat, and cancer, with a relatively high incidence of lymphoma and mast cell tumours.
One size fits all — A general rule of thumb is that the first year of a dog's life is equivalent to 15 human years, the second year equivalent to 9 human years, and each subsequent year about 5 human years. [3] So, a dog age 2 is equivalent to a human age 24, while a dog age 10 is equivalent to a human age 64.
Aortic stenosis is a disease of the heart valve in which the opening of the aortic valve is narrowed. [23] One study suggests a high predisposition in the breed. No severe cases were found in adult dogs, and most moderate to severely affected dogs died before one year of age, leading the authors to speculate that the disease is more severe in ...
A 2024 UK study found the average life expectancy of the breed to be 10.6 years, compared to an average of 12.7 for purebreeds and 12 for crossbreeds. [ 34 ] [ 35 ] A 2005 Swedish study of insurance records found 83% of Great Danes died by the age of 10, higher than the overall rate of 35% of dogs dying by the age of 10.

The AKC standard height (per their website) for this breed is 30 inches (76 cm) at the shoulder for males and 27.5 inches (70 cm) (minimum) at the shoulder for females. A typical male can weigh 150–250 pounds (68–113 kg), a typical female can weigh 120–200 pounds (54–91 kg), with very large individuals reaching 300 pounds (140 kg) or more.
If true, this would challenges the common belief [3] [4] in existence of a fixed maximal human life span. Biodemographic studies have found that even genetically identical laboratory animals kept in constant environment have very different lengths of life, suggesting a crucial role of chance and early-life developmental noise in longevity ...
A 2022 study in the UK of veterinary data found a life expectancy of 7.39 years, the second lowest of all breeds in the study. [9] A 2024 UK study found a life expectancy of 9.8 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds. [10]
