10 Dog Breeds With the Shortest Lifespan

Despite our deep bonds with our four-legged best friends, we know our time with these dogs can’t last forever. If you’re considering adding a dog to your home, you may want to learn more about breed life expectancy and general health. Certain dog breeds have shorter lifespans than others. This is especially true among larger breeds, whose lifespans can sometimes be shorter than those of small breeds by as much as 5-8 years. Below are ten dog breeds with the shortest lifespans.

Scottish Deerhound (9.5 years)

Known as the “Royal Dog of Scotland,” this breed exhibits an exceptionally high prey drive, which often translates to an active and spirited puppyhood. However, as they mature, typically between 3 to 5 years of age, they can undergo a noticeable shift towards becoming more sedentary, earning the nickname of “couch potato.” To maintain their physical and mental well-being, it’s crucial to provide ongoing opportunities for exercise and mental stimulation.

Rottweiler (9.5 years)

Pet Premium Pet Health Insurance reports that the Rottweiler ranks as the most costly dog breed to care for. This robust breed, known for its fluctuating energy levels from couch potato to tornado, thrives best in a spacious, securely fenced yard. Aside from their iconic appearance, Rottweilers are devoted, obedient, and alert.

Saint Bernard (9.5 years)

Despite an unfavorable depiction in the Stephen King novel “Cujo,” the Saint Bernard is lovable, devoted, and playful. This large dog, who can weigh up to 180 pounds, gained popularity for their heroic role in rescuing humans from the harsh conditions of the Swiss Alps’ icy winds and snowstorms. These wonderful dogs do face some predispositions to conditions like cancer and a heart condition called dilated cardiomyopathy.

Newfoundland (9 years)

Named after the Canadian province the breed originated from, the Newfoundland is celebrated for their versatility as both a devoted companion and diligent worker. Renowned for their intelligence, strength, and remarkable swimming ability, this breed excels in various roles. Notably, Newfoundlands have earned a reputation as natural caregivers and protectors, with their nurturing instincts showcased famously in literature, such as Peter Pan, where a Newfoundland named Nana served as the beloved nanny. To that end, their gentle demeanor and unwavering loyalty make them cherished family members and valued assets in roles ranging from water rescue to therapy work.

Bullmastiff (9 years)

The Bullmastiff, slightly smaller than the English Mastiff, combines the strength of their Mastiff lineage with the agility of the Bulldog. Renowned for their exceptional tracking abilities, Bullmastiffs possess a heightened sense of smell. Alongside their innate protective instincts and unwavering loyalty to their families, they excel as guardians and beloved companions. While this loveable pup is low-energy Mastiff breed who adapts well to most home environments, his size makes him best suited to a house with a fenced yard.

Great Dane (8.5 years)

Great Danes are renowned for their impressive size, often holding Guinness World Records for being the tallest dogs. Beyond their stature, they are cherished for their gentle and affectionate nature, making them beloved companions for families. With their loyalty and playful demeanor, Great Danes bring joy and companionship to any household fortunate enough to welcome them. These gentle giants may face an elevated risk for conditions such as bloat and bone cancer.

Greater Swiss Mountain Dog (8 years)

As one of the four Sennehunds, the Greater Swiss Mountain Dog stands out for their prowess in various dog sports, including weight pulling and agility, reflecting their heritage as a versatile working dog. Originating from a lineage of all-around workers, this breed has historically been valued for tasks such as standing guard, herding cattle, and pulling carts.

Mastiff (8 years)

The English Mastiff, the largest Mastiff breed, exhibits an imposing size and imposing appearance. Fortunately, their calm demeanor complements this ferocious facade. With a history dating back centuries, they have been celebrated for their gentle and patient temperament, exemplified by a legend from the 1400s where a Mastiff saved an English knight at the Battle of Agincourt. The Mastiff faces an elevated risk for conditions like bloat and a kidney defect called cystinuria.

Irish Wolfhound (7 years)

Hailing from Ireland, the majestic Irish Wolfhound showcases an impressive size and noble appearance. Sadly, Irish Wolfhounds possess a short lifespan due to their massive stature. Despite this, owning an Irish Wolfhound promises days filled with admiration, love, and an abundance of affectionate, sloppy kisses from this gentle giant.

Bernese Mountain Dog (7 years)

Originating from Switzerland, the Bernese Mountain Dog is a large breed cherished for their gentle nature and striking tricolor coat. These large dogs boast a well-muscled build with a regal appearance. Their appearance is also characterized by a broad head, expressive eyes, and a bushy tail. Affectionate and loyal, they are additionally known for their love of children and goofy smiles. Despite the breed’s short lifespan averaging around six to eight years, they remain popular.

Increasing your dog’s lifespan involves a combination of proactive healthcare and responsible breeding practices. Regular veterinary care is paramount, as routine check-ups and vaccinations help detect and prevent health issues early on. Additionally, maintaining a healthy weight through proper diet and exercise can significantly impact your dog’s longevity. Ensure your furry friend receives a balanced diet tailored to their nutritional needs. Don’t underestimate the power of exercise!

Mental stimulation, such as interactive toys and training sessions, also contributes to their overall well-being. This can help prevent cognitive decline as they age.

They also conduct thorough health screenings and genetic testing to minimize the risk of hereditary conditions. They provide proper socialization and care for their puppies from birth, setting them up for a healthy start in life. Avoid puppy mills and backyard breeders, who often prioritize profit over the welfare of the animals, is essential.
