Every dog owner wishes their furry friend could stay with them forever, but the reality is that some breeds naturally live longer than others. Understanding which breeds have shorter lifespans and which ones tend to stick around for many years can help you make informed decisions when choosing your next companion. Whether you’re drawn to a giant breed with a big heart or a tiny pup that might outlive your houseplants, knowing what to expect makes all the difference.
Lifespan estimates are averages and can vary based on genetics, diet, exercise, veterinary care, and overall lifestyle. Individual dogs may live shorter or longer lives than typical breed expectations.
1. Great Dane
Known as the gentle giant of the dog world, Great Danes typically live only 7 to 10 years. Their massive size puts tremendous strain on their hearts and joints, leading to earlier health complications.
Despite their shorter time with us, these dogs pack a lifetime of love into every moment. They’re famous for thinking they’re lap dogs, even when they weigh over 150 pounds!
2. Bernese Mountain Dog
With their striking tri-colour coats and affectionate personalities, Bernese Mountain Dogs sadly average just 7 to 10 years of life. Cancer rates run particularly high in this breed, cutting many lives tragically short.
Originally bred to pull carts in the Swiss Alps, these working dogs form incredibly strong bonds with their families. Their devotion makes every year together truly precious.
3. Irish Wolfhound
Standing as tall as a small pony, the Irish Wolfhound lives approximately 6 to 8 years. Their ancient lineage dates back to Roman times, but their enormous frames come with serious health trade-offs.
Heart disease and bone cancer frequently affect this noble breed. Yet their calm, dignified temperament makes them unforgettable companions during their time with us.
4. Mastiff
Weighing up to 230 pounds, Mastiffs generally live between 6 and 10 years. These ancient guardians have protected humans for thousands of years, but their size creates vulnerability to joint problems and heart conditions.
Their drooling might require a towel nearby, but their protective yet sweet nature wins hearts instantly. Every slobbery kiss feels like a gift.
5. Newfoundland
Famous for their water rescue abilities, Newfoundlands typically live 9 to 10 years. Their thick, water-resistant coats and webbed feet make them incredible swimmers, but their large size brings health challenges.
These dogs are legendary for their patience with children and heroic rescue stories. One Newfoundland named Seaman even accompanied Lewis and Clark on their famous expedition!
6. Saint Bernard
Alpine rescue dogs with hearts of gold, Saint Bernards live roughly 8 to 10 years. Their history of saving lost travellers in snowy mountain passes is legendary, though their massive bodies age faster than smaller breeds.
Hip dysplasia and bloat are common concerns. Still, their patient, tolerant nature makes them wonderful family members despite their shorter lifespan.
7. Rottweiler
Powerful and confident, Rottweilers generally live 9 to 10 years. Originally bred to drive cattle and pull carts for butchers, their strength and loyalty are unmatched.
Cancer and heart issues often affect this breed as they age. Proper training and socialization reveal their surprisingly affectionate side, making them devoted protectors who love deeply but leave too soon.
8. Chihuahua
Tiny but mighty, Chihuahuas often live an impressive 14 to 16 years or even longer. Their small size means less stress on vital organs, allowing them to thrive well into their teens.
Named after a Mexican state, these pint-sized pups have huge personalities. They’re fiercely loyal and surprisingly bold, often forgetting they weigh less than a house cat!
9. Dachshund
Those adorable sausage-shaped bodies help Dachshunds live 12 to 16 years on average. Bred to hunt badgers in Germany, their tenacious spirit and long spines require careful handling to prevent back injuries.
Their stubborn streak is legendary, but so is their charm. Dachshunds come in three coat varieties and two sizes, offering plenty of personality in compact packages.
10. Toy Poodle
Intelligent and hypoallergenic, Toy Poodles frequently reach 14 to 18 years of age. Their sharp minds need constant stimulation, making puzzle toys and training sessions essential for their happiness.
Don’t let the fancy haircuts fool you – these dogs were originally water retrievers. Their curly coats protected them from cold water while hunting, and their brains make them easy to train.
11. Yorkshire Terrier
Weighing just seven pounds or less, Yorkshire Terriers commonly live 13 to 16 years. Their silky coats and feisty attitudes make them popular companions, especially in urban settings where space is limited.
Originally bred to catch rats in textile mills, Yorkies retain their fearless hunting instincts. They’ll bravely defend their homes despite being small enough to fit in a purse!
12. Shih Tzu
Bred as royal lap dogs in ancient China, Shih Tzus typically enjoy 10 to 18 years of life. Their name means “lion dog,” though their temperament is far more cuddly than fierce.
These affectionate companions thrive on human attention and adapt wonderfully to apartment living. Regular grooming keeps their luxurious coats tangle-free and their eyes clear from hair irritation.
13. Australian Cattle Dog
Energetic herders with remarkable endurance, Australian Cattle Dogs often live 12 to 16 years. One famous Cattle Dog named Bluey holds the Guinness World Record for oldest dog ever, reaching an astounding 29 years!
Their intelligence and work ethic demand plenty of mental and physical challenges. Without proper exercise, they’ll find creative (and possibly destructive) ways to entertain themselves.
14. Beagle
With their soulful eyes and floppy ears, Beagles generally live 12 to 15 years. Bred as scent hounds for rabbit hunting, their noses contain approximately 220 million scent receptors compared to humans’ mere 5 million.
Their friendly, curious nature makes them excellent family pets. Just watch your countertops – Beagles are notorious food thieves with impressive jumping abilities for their size!
