You’re looking at that little white cloud of fur and wondering how many years you’ve actually got left together. It’s a heavy question. Honestly, the Maltese is one of those breeds that seems to defy the laws of nature by looking like a puppy even when they’re basically a senior citizen.
So, how long does a Maltese live?
The short answer is a long time. These tiny athletes—and yes, they are surprisingly athletic—typically live between 12 and 15 years. But that’s just a median. Many owners report their Maltese hitting 16, 17, or even 18 years with the right mix of genetics and luck. There are even anecdotal accounts of these dogs reaching the ripe old age of 20, though those are the "marathon runners" of the breed.
The Reality of the Maltese Lifespan
We often hear the "one dog year equals seven human years" rule. It’s a myth. Total nonsense. In reality, a Maltese hits adulthood much faster than we do, then slows down their aging process significantly.
According to recent data from the American Kennel Club (AKC) and veterinary studies from 2024 and 2025, a one-year-old Maltese is roughly equivalent to a 15-year-old human. By age two, they’re about 23 or 24. After that, they only "age" about four human years for every calendar year. This slow-burn aging is why small breeds outlive the giants like Great Danes, who might only see seven or eight birthdays.
Why do they live so long?
Scientists aren't 100% sure why small dogs live longer than big ones. One theory is that large dogs age "faster" in a biological sense because they grow so rapidly from puppyhood. A Maltese stays small. Their cells aren't under the same pressure to expand and divide at breakneck speeds.
What Actually Determines How Long Your Maltese Lives?
It isn't just about the number on the calendar. It’s about the "mileage."
The Hidden Danger: Dental Health
This is the one that catches people off guard. You might think "dog breath" is just a fact of life, but for a Maltese, it’s a warning sign. Because their mouths are so tiny, their teeth are crowded. This makes them absolute magnets for tartar and bacteria.
If you don't brush those teeth—and I mean daily—that bacteria can enter the bloodstream. From there, it travels straight to the heart and kidneys. Veterinary experts at VIDA Veterinary Care note that untreated dental disease can actually shave one to three years off a dog's life. It’s not just about a pretty smile; it’s about organ failure prevention.

The "White Dog" Heart Issues
Maltese are prone to something called Mitral Valve Disease (MVD). Essentially, the heart valve wears out and starts to leak. It’s incredibly common in older Maltese, affecting nearly 75% of those who reach senior status.
The good news? If you catch it early through a regular vet checkup (they’ll hear a "murmur"), there are medications that can keep them going for years.
Weight and the "Soulful Eyes" Trap
It is so easy to overfeed a 7-pound dog. One extra treat for a Maltese is like a human eating a whole Snickers bar as a snack. Obesity is a silent killer here because it puts immense strain on their tiny joints and their even tinier hearts. A lean Maltese will almost always outlive a "cuddly" one.
Common Health Hurdles to Watch For
- Tracheal Collapse: If your dog makes a "honking" sound when they get excited or pull on their leash, that’s their windpipe weakening. Switch to a harness immediately. This keeps the pressure off the throat.
- Luxating Patella: This is a fancy way of saying their kneecap pops out of place. It’s common, and while not usually fatal, it can lead to arthritis which slows them down.
- Liver Shunts: This is usually a genetic issue found in younger dogs where blood bypasses the liver. It's serious but often treatable with surgery if caught early.
Real Examples of Longevity
Look at the famous case of Trouble, the Maltese owned by billionaire Leona Helmsley. Trouble lived to be 12, which is respectable, but she was famously pampered with high-end food and a security guard. Then you have "regular" pets like Yasmina, a dog found in a Roman tomb in Carthage. Skeletal analysis suggested she was quite old for a dog of that era, proving that humans have been keeping these little guys alive through dedicated care for over 2,000 years.
Making the Most of the Golden Years
When a Maltese hits age 9 or 10, they officially enter their "senior" phase. You’ll notice the muzzle getting a bit whiter. They might sleep through the mailman’s arrival instead of losing their mind.
At this stage, your vet visits should probably move to twice a year. Blood work becomes your best friend. It can catch kidney issues or "haywire" immune systems (like hemolytic anemia) before your dog even shows symptoms.
Actionable Steps for a Longer Life
If you want to maximize the time you have, stop treating these things as optional:
- Professional cleanings: Yes, they are expensive. Yes, they require anesthesia. But they are the single best thing you can do for a senior Maltese.
- Water filtration: Some studies suggest that the sensitive systems of toy breeds do better with filtered water to avoid excess mineral buildup that leads to kidney stones.
- Low-impact exercise: Don't stop walking them. Even a 10-minute sniff-around-the-block keeps their brain sharp and their heart pumping.
- Blood work at age 7: Get a "baseline" while they are healthy so your vet knows what's normal for your specific dog.
The Maltese isn't just a lap dog; they are a long-term commitment. They are hardy, ancient, and surprisingly tough. If you watch their weight and keep those teeth clean, you’re looking at a decade and a half of companionship. It’s never enough time, but for a dog, it’s a pretty great run.
To start today, check your dog's gums. If they're red or the breath is stinky, book a dental consultation. That one move could literally add years to the clock.
