Not all dogs are blessed with long lives. Genetics, size, and health predispositions play a major role in how long a breed tends to live. Here are 10 dog breeds known for having shorter lifespans—and the reasons behind it.
Great Dane
Great Danes typically live only 6 to 8 years. Their enormous size puts stress on the heart and joints, and they are highly prone to dilated cardiomyopathy (DCM). According to a 2021 study by the Royal Veterinary College, 42% of Great Danes die of heart-related conditions.
Bernese Mountain Dog
Bernese Mountain Dogs have an average lifespan of 6 to 8 years. A staggering 50% of Berners die from cancer, especially histiocytic sarcoma, according to the Bernese Mountain Dog Club of America. Their large size also contributes to shorter life expectancy.
Irish Wolfhound
This giant breed lives just 6 to 8 years on average. The Irish Wolfhound’s rapid growth leads to bone cancer (osteosarcoma) and heart disease. A UK Kennel Club survey showed cancer accounted for over 40% of Irish Wolfhound deaths.
Bulldog
With a lifespan of only 7 to 9 years, Bulldogs are plagued by numerous health issues due to extreme breeding. Their flat faces (brachycephalic features) lead to breathing difficulties, and over 70% suffer from hip dysplasia, according to the Orthopedic Foundation for Animals.
Saint Bernard
Saint Bernards live around 8 years. Their sheer size makes them vulnerable to joint issues and heart problems. A 2022 Veterinary Pathology report noted a high incidence of cardiomyopathy and bone cancer, contributing to early mortality.
Rottweiler
Rottweilers have a life expectancy of 8 to 10 years. Cancer, particularly bone cancer, is their leading cause of death. Studies from the Morris Animal Foundation show that nearly 45% of Rottweilers die of cancer-related illnesses.
Newfoundland
Newfoundlands average 8 to 10 years of life. Their most common causes of death include heart disease and bloat (gastric dilatation-volvulus). Research from Purdue University links bloat risk to deep-chested breeds like Newfoundlands, shortening their lifespan significantly.
Boxer
Boxers live between 9 and 10 years and have one of the highest cancer rates among all breeds. According to the American Boxer Club, about 38% of Boxers die from cancer, especially mast cell tumors and lymphomas.
Cavalier King Charles Spaniel
Despite being small, Cavaliers live only 9 to 11 years on average. Over 50% develop mitral valve disease (MVD) by age 5, according to a study published in the Journal of Veterinary Internal Medicine. Heart failure is a major cause of death.
Doberman Pinscher
Dobermans have a lifespan of 10 to 12 years, but sudden death is a concern due to inherited heart disease. Up to 60% are affected by dilated cardiomyopathy, with many dying unexpectedly, according to data from the Doberman Pinscher Health Foundation.
