More years, more tail wags, fewer tears, and a home that feels fuller.
Picking a dog is not just about looks. It is about the dog’s life you will share. Many pet parents want time, not a quick goodbye.
Some small dogs often reach 15 years or more with the right care. You will see them with the Longest living dog breeds and healthiest dog breeds. Large dogs can be wonderful, but many larger breeds have shorter lifespans, so their average lifespan target is often lower.
It feels hopeful to plan for a dog’s lifespan that can stretch into the senior years, like the oldest dog. Dogs live on habits, and daily choices matter too.
A balanced diet, regular exercise, and regular vet check-ups help protect overall health.
Household Favorite Dog Breeds With Lifespans Over 15 Years
1. Chihuahua
Average lifespan: 12 to 18 years.
Chihuahuas are tiny, but they do not act tiny. This furry friend often bonds with one person, then guards that bond like a treasure. Many are bold little watchdogs who alert you to every hallway sound.
Sounds crazy, right? They were originally bred for companionship, and they still crave closeness. They like warmth, soft beds, and being near your voice. Their small size also makes them easy for apartment living, as long as they get gentle play and short walks.
Their dog’s lifespan can hit the longest lifespan, and this is why they often show up on Longest living dog breeds lists, when you protect them from injuries. The biggest danger is not age. It is accidents.
A drop from a couch can be a big deal. So can rough play with other dogs. Keep them safe, and keep them lean. A healthy weight supports joints and heart health, and it helps them stay spry for longer lives. Feed measured meals, not endless snacks.
Choose a proper diet with real protein and fiber, plus healthy fats in sensible amounts.
Key Points:
Use the steps for sofas and beds to prevent jumps
Keep them warm, since cold can stress their body
Pick soft toys and calm games instead of wild leaps
Do routine vet visits for teeth, knees, and heart checks
But wait, there’s more! Chihuahuas can get anxious when the world feels loud. A steady routine and a calm environment can support longevity by lowering stress and helping their overall health stay steady.
2. Dachshund
Average lifespan: 12 to 16 years.
Dachshunds are famous for their long body and brave spirits. Yes, wiener dogs can be the longest living dog breeds in the right home. They were originally bred to hunt, so they still have that fearless “I got this” energy.
They love sniffing, digging, and chasing tiny mysteries across your living room rug. Many become great family pets when kids learn gentle handling. They are funny, loyal, and a bit stubborn, in a way that makes you grin.
Their dog’s lifespan is closely tied to back care. Extra weight puts pressure on the spine. Jumping off furniture can add strain, too. So this is one place where weight management is not a buzzword. It is a real kindness.
Keep them at a healthy weight with a balanced diet and calm treat habits. For movement, moderate exercise beats intense bursts. Think steady walks and low games.
It gets even worse, though, when boredom hits. Dachshunds can turn into tiny chaos machines if their brain has nothing to do.
Key Points:
Use ramps for sofas and beds to cut risky jumps
Keep playing low to the ground, not airborne
Split daily exercise into short sessions
Book a vet visit if you notice stiffness or yelps
Here’s the good part. When you plan for safe movement and stable meals, you support longevity in a way that feels simple. Add gentle training for mental stimulation, and their senior years can stay bright and playful.

The Shih Tzu is a cuddle expert with a gentle manner. This small breed was made to be close to people, and it shows. These small dogs love quiet together time, then pop up with little bursts of play.
Many fit into busy homes, and they can also shine in apartment living. Their vibe is sweet and calm, like a tiny friend who always wants to hang out near your feet.
Their life expectancy often depends on comfort care. Their flatter face can make heat harder, so keep walks cooler and shorter during warm days. A calm pace protects breathing and helps the dog’s life feel easy. Regular grooming is also key. Their coat can mat fast, and mats can pull at the skin.
Consistent grooming keeps them comfy and helps you spot bumps or irritation early. Also, take dental hygiene seriously. Small dogs can build plaque quickly, and tooth pain can hide behind a cute smile.
Key Points:
Brush and comb often to prevent mats
Wipe the face after meals to keep skin clean

Many are social dogs who enjoy visitors and learn new routines quickly. They often love games, learning tricks, and trotting around with confidence like they own the room.
AKC notes that their longest lifespan often stays strong because many are generally healthy, but good habits still matter. Keep them lean, since extra pounds can stress joints. Offer regular exercise, but keep it safe.
