A healthy dog really does make life happier—for both of you. And while no dog is guaranteed a lifetime without sniffles, aches, or surprise vet visits, some dogs are simply built to stay healthier for longer.
These are the dogs that tend to live well into their senior years, bounce back faster, and spend more time enjoying life than dealing with health issues.
Studies consistently show that dogs who maintain a healthy weight can live up to 2 years longer than overweight dogs. That alone tells us something important—genetics matter, but everyday care matters just as much.
When strong genetics are paired with regular exercise, balanced nutrition, and routine vet checkups, dogs can thrive well into old age.
If you’re looking for a companion who’s easier to care for, stays active for years, and brings joy without frequent health scares, you’re in the right place.

Health‑Boosting Dog Breeds with Extended Lifespans and Low Maintenance
1. Chihuahua
Chihuahuas may be tiny, but they often forget it—and that confidence is part of their charm. These loyal, energetic dogs are known for their sharp intelligence and strong bond with their humans.
Despite their small size, these tiny dogs are eager for life and love being close to their people, making them long-term and affectionate companions.
It’s not uncommon for them to live close to 20 years. They generally remain healthy for most of their lives and are remarkably resilient to many common illnesses seen in other breeds. This long lifespan allows pet parents to enjoy their company for a significant part of their lives.
Health notes to keep in mind
Prone to obesity, so regular exercise is important
Simple activities like indoor play or fetch work well
Obesity can lead to joint problems in small dogs
Predisposed to some breed-specific issues
These include heart problems, eye issues, and loose kneecaps
With proper exercise and routine care, Chihuahuas tend to stay active and healthy well into old age. Their low maintenance needs and long life expectancy make them a smart choice for anyone looking for a small dog with big health benefits.
2. Beagle
Beagles are famous for their powerful noses and food-driven curiosity. They follow scents everywhere—even when it gets them into mischief.
As pets, they are loving, affectionate, and full of charm. Because they are highly motivated by food, they do best with scent-based activities and a carefully controlled diet, as mentioned by PetMD.
Bred to hunt small animals like hares and rabbits, Beagles are naturally hardy dogs. They have lots of energy and stay healthier when they live an active lifestyle.
Regular walks, playtime, and mental stimulation help keep them happy and balanced. When their need for movement is met, they tend to thrive both physically and mentally.
Health highlights to know
Known for being durable and generally healthy
Average lifespan of 10–15 years
Health issues are more common in older dogs
Possible concerns include eye, hip, and heart problems
Poor breeding can lead to serious conditions
A controlled diet is essential to prevent overeating
With proper exercise, good breeding, and mindful feeding, Beagles make resilient companions who stay active and healthy for most of their lives.
3. Dachsund
The Dachshund is hard to ignore, thanks to those short legs and long body. Often called “wiener dogs,” this small dog breed is clever, playful, and deeply devoted to their families. These affectionate dogs love being close to their people and often make excellent lapdogs and couch companions.
Originally bred as badger hunters, Dachshunds are more muscular and energetic than they look. They usually need only moderate exercise to stay healthy. However, their long backs need special care. Too much jumping or excessive running can increase the risk of injury, especially as these dogs age.
Health and care highlights
Average lifespan of 12–16 years
Prone to back issues, including intervertebral disc disease (IVDD)
Other possible concerns include epilepsy and diabetes
Basic training helps manage their stubborn streak
Moderate exercise is best for long-term health
Long-haired varieties need more grooming than others
With mindful care and proper activity, Dachshunds fit well into the category of health-boosting dog breeds with extended lifespans and low maintenance. Their loving nature and long life make them a rewarding companion for many years.
4. Basenji
The Basenji is often called the “cat of the dog world,” and for good reason. This breed is independent, alert, and even grooms itself.
With an energetic mind and an athletic body, Basenjis are always on the move. Britannica states that they don’t bark like most dogs and instead make a unique yodel-like sound, which adds to their charm.
Originally bred as hunting dogs, Basenjis are intelligent and active by nature. They need plenty of mental and physical stimulation to stay happy and out of trouble. Secure play areas and leash walks are important, as their curiosity and independence can easily lead them astray if left unsupervised.
Health and care highlights
Average lifespan of 13–14 years
Generally healthy with few serious issues
Genetically predisposed to Fanconi syndrome
Also prone to hypothyroidism and hip problems
Thrive with regular exercise and mental challenges
Thanks to their durability, cleanliness, and relatively low health concerns, Basenjis make great pets. With the right care and structure, they remain healthy and active for most of their lives.
5. Shih Tzu
The Shih Tzu is a wonderful choice for anyone looking for a small dog that adapts easily to apartment or small-home living. These charming companions love attention and prefer staying close to their people. If cuddling is your thing, a Shih Tzu will happily stay by your side all day.
With a moderate energy level, Shih Tzus need daily exercise but nothing intense. They enjoy playtime and short walks, then settle in as relaxed lap dogs.
Training is important, as they are smart and can become stubborn without clear guidance. Their cheerful and gentle nature makes them a joy to live with.
Health and care highlights
Can live up to 18 years
Generally low shedding and considered hypoallergenic
Weekly brushing keeps the coat soft and smooth
Regular trims help manage coat length
Their brachycephalic face may cause breathing issues
Prone to overheating, especially in warm conditions
With proper grooming, routine exercise, and mindful care, Shih Tzus fit well among health-boosting dog breeds. Their affectionate nature and long life make them loving companions for many years.
6. Chinese Crested
The Chinese Crested is a unique and elegant dog known for being deeply devoted to their owners. According to the AKC, this breed comes in two varieties: hairless and powderpuff.
Both need regular grooming to keep their coats healthy, but the hairless variety requires extra care to protect its sensitive skin. Sweaters are a must in colder weather to keep them warm and comfortable.
Though small in size, Chinese Cresteds are known for their long lifespan, typically living between 13 and 18 years. Their mostly hairless bodies make them a great option for people with allergies.
However, this means they are sensitive to extreme temperatures and need protection from both cold and sun exposure.
Health and care highlights
Long lifespan of 13–18 years
Hypoallergenic, especially the hairless variety
Need skin care and sun protection for hairless dogs
Prone to eye issues, luxating patella (loose kneecaps), and epilepsy
Powderpuff variety requires regular grooming
With their affectionate nature, allergy-friendly coat, and long life, Chinese Cresteds are a smart pick. Their charm and loyalty make them wonderful lifelong companions.
7. Cavalier King Charles Spaniel
The Cavalier King Charles Spaniel is often admired for its puppy-like appearance that seems to last a lifetime. These small to medium-sized dogs have a calm, affectionate personality and truly thrive on closeness with their humans or other pets.
These dogs are smart and eager to please, which makes training a fairly smooth process. They respond well to positive reinforcement and enjoy learning new tricks or commands.
While they do need regular grooming — including brushing to keep their silky coats tangle-free, ear cleaning to prevent infections, and occasional trips to the groomer — Cavaliers are considered low shedders. Their grooming needs are manageable and won’t overwhelm most pet parents.
Health and care highlights
The average life span is about 10 to 14 years
Exercise requirements are moderate, easily met with a couple of 20-minute walks each day
Prone to some health concerns, including heart disease (particularly mitral valve disease), ear infections, and neurological issues
Other common issues include hip dysplasia, cherry eye, dry eye, and cataracts
Regular vet check-ups and monitoring are important to catch problems early
With attentive care, a balanced diet, and regular exercise, Cavaliers can enjoy a happy, comfortable life. Their sweet temperament, ease with children and other pets, and willingness to be close to their humans make them truly special companions who enrich the lives of those around them.
