7 of the Longest Living Dog Breeds
A dog's size offers a useful clue about lifespan, but breed estimates cannot predict your years together. Compare seven long-living breeds and the care commitments to consider before adopting.


If you're choosing a dog to adopt, it's natural to hope for many years together. These seven breeds often have long lifespans, but their daily care needs matter just as much as the numbers.
Understanding Dog Lifespan by Breed
Small dogs usually live longer than large dogs. Size is one of the strongest general clues to lifespan, as the AKC's lifespan overview explains. Health and individual differences still matter.
These breeds appear alphabetically, not in a longevity ranking. Their overlapping ranges are estimates, not promises.
| Breed | Estimated lifespan | Care commitment |
|---|---|---|
| Chihuahua | 14 to 16 years | Regular dental care |
| Dachshund | 12 to 16 years | Back health and weight control |
| Papillon | 14 to 16 years | Daily activity and training |
| Pomeranian | 12 to 16 years | Frequent coat brushing |
| Shih Tzu | 10 to 18 years | Grooming and heat precautions |
| Toy Poodle | 10 to 18 years | Regular haircuts and enrichment |
| Yorkshire Terrier | 11 to 15 years | Coat and dental upkeep |
Ranges come from the AKC's longest-living breed guide and the individual breed profiles linked below.
Chihuahua
Estimated lifespan: 14 to 16 years. Chihuahuas often enjoy close companionship, short walks, and indoor play. Small size does not mean they want to spend every day being carried.
Plan for tooth brushing and veterinary dental checks. A Chihuahua or Chihuahua mix at a shelter or breed rescue is worth meeting, especially when staff can describe that dog's personality.
Dachshund
Estimated lifespan: 12 to 16 years. This curious, active dog usually needs walks and opportunities to sniff, not just couch time.
A long lifespan does not mean freedom from health problems. Protect back health by keeping your dog at a healthy weight and asking your vet about safe exercise, stairs, and jumping. Sudden back pain or trouble walking needs prompt veterinary attention.
Papillon
Estimated lifespan: 14 to 16 years, according to the AKC Papillon profile. That range cannot predict an individual dog's lifespan.
Papillons are alert, trainable companions who often enjoy learning tricks. Budget time for daily walks, play, and short training sessions. A tiny dog can still need plenty to do.
Pomeranian
Estimated lifespan: 12 to 16 years. A Pomeranian's fluffy coat needs frequent brushing, and dental care belongs in the routine too.
Most enjoy everyday walks and play. Ask the shelter about barking and comfort when left alone, especially if you live in an apartment. Grooming and noise may affect your daily life more than a lifespan estimate.
Shih Tzu
Estimated lifespan: 10 to 18 years, from the AKC Shih Tzu profile. This wide range is not a promise that your dog will reach 18.
Long coats need daily attention; shorter cuts still need regular grooming. Take breathing comfort seriously and avoid exercise in heat. Labored breathing or collapse is an emergency, not something to watch overnight.
Toy Poodle
Estimated lifespan: 10 to 18 years. The AKC Toy Poodle profile gives this broad breed estimate, not an individual forecast.
Toy Poodles are bright companions who need regular haircuts, brushing, and mental activity such as training or food puzzles. A poodle mix does not automatically share this range; ancestry, size, and health can differ.
Yorkshire Terrier
Estimated lifespan: 11 to 15 years. Yorkies are small terriers who often enjoy walks, exploration, and play. Their coats need brushing or regular trims, and their teeth need ongoing care.
Choose the individual dog, not just the breed label. Compare dog breeds for first-time owners, then ask how a particular dog's behavior fits your home.
Choosing a Dog for the Years Ahead
When you browse adoptable dogs, ask about estimated age, medical records, dental condition, and daily care needs. Choose a dog whose needs fit your routine, then plan when to take your newly adopted dog to the vet.
As your dog ages, regular checkups can help identify problems earlier. The AVMA's senior pet guidance recommends more frequent veterinary visits for older pets.
Consider pet insurance versus emergency savings before unexpected bills arrive. Insurance exclusions, waiting periods, and pre-existing-condition rules vary by policy. Neither insurance nor a breed label guarantees a longer life.
Frequently asked questions
Which dog breed lives the longest?
There is no single breed guaranteed to live the longest. Several small breeds have overlapping lifespan estimates, including Chihuahuas, Papillons, and Toy Poodles. An upper limit of 18 years does not establish that a breed usually outlives one listed at 14 to 16 years. Choose for health and lifestyle fit, not the highest number.
Why do small dogs usually live longer than large dogs?
Large dogs generally age faster, although the biology behind the size difference is complex. Size helps describe broad patterns, not an individual dog's future. A small dog can develop serious illness early, while a larger dog may live beyond its breed's estimate. Keep preventive care consistent regardless of size.
Do mixed-breed dogs live longer than purebred dogs?
Mixed-breed dogs may have a longevity advantage in some comparisons, but being a mix does not guarantee a longer life. Size, inherited conditions, and individual health still matter. For a shelter dog, ask about known medical history and estimated age rather than trying to calculate lifespan from a guessed breed mix.
Can a dog live for 20 years?
Yes, some dogs reach 20 years, but that is unusual and should not be your expectation. Breed lifespan ranges are planning tools, not deadlines or guarantees. If you adopt an older dog, focus on comfort, mobility, appetite, and enjoyable daily routines rather than measuring success by reaching a particular birthday.
What can I do to support my adopted dog's long-term health?
Keep your dog at a healthy weight and build a preventive care plan with your vet. Include appropriate exercise, dental care, vaccinations, and parasite prevention. Ask which health risks deserve attention for your individual dog. Report changes in appetite, thirst, breathing, movement, or behavior rather than assuming they are simply signs of aging.
