9 Guard Dog Breeds with a Long Lifespan That'll Watch Your House

Most people think guard dog breeds are huge and live less. But guess what? You can actually have a dog that will bark at your mailman for years even after its age of retirement!

According to PetMD, small dog breeds have 10 to 15 years of average lifespan and can even go longer if they skip the doggy donuts.

If you are looking for a lifelong companion who doubles as a furry alarm system, you are in luck. We are diving into the 9 longest living dog breeds with minimal vet bills (Thank goodness).

Guard Dog Breeds With a Long Lifespan

Before you assume all good guard dogs must weigh 100 pounds and chew bricks for fun, let’s burst the myth bubble. Guarding is not just about extreme strength. It is about alertness, loyalty, and a healthy weight.

Many small dogs live longer and make great guard dogs. They are suspicious, loud, and love their humans fiercely. Better yet, the ones we have rounded up tend to dodge major health concerns most pet owners deal with.

1. Akita

Akita

The Akita is basically the detective of the dog world. It is stoic, loyal, alert, and will ruin an intruder’s afternoon without making a fuss. Originally bred in Japan for guarding royalty, the Akita has a built-in sense of duty and suspicion.

What makes it even better? These fur tanks can live up to 10 to 14 years, according to WebMD. They are surprisingly low on major health problems aside from potential hip dysplasia.

Providing regular exercise and mental stimulation can help contribute to their health. Plus, they don’t bark much, which makes the one time they do bark more terrifying.

2. Belgian Malinois

Belgian Malinois

If the Belgian Malinois had a LinkedIn profile, it would say: ‘Specializes in protection, herding, and serving as intruders’ worst nightmare.’ These guys are the choice for military and police dogs worldwide, as mentioned by Britannica.

They are fast, focused, and loyal. Despite their active lifestyle, Malinois are built like steel, free from many joint and heart issues that plague other large dogs.

With regular exercise and a job to do, they can easily live for 14 strong years. And don’t let that slim build fool you, they don’t just bark, they bite like a pro. With proper training, they will ensure you stay safe.

3. Chihuahua

Chihuahua

Yes, we are serious. Underneath that tiny dog is a heart full of suspicion and a voicebox that is 100% volume. Chihuahuas are not just ankle-biting memes; they are fiercely loyal and alert.

They will notify even when a leaf moves due to their vigilant nature, according to Orvis. The best part: they can live forever (okay, not really, but close).

They often reach 17 years or more with minimal health problems if fed well and not over-spoiled. Their small size means less joint issues and less pressure on internal organs.

4. Yorkshire Terrier

Yorkshire Terrier

Time for Yorkies! They are scrappy little watchdogs with a fashionable twist. Originally developed to chase rats in a mine (yes, really).

They have instincts for alertness and loyalty, making them surprisingly great family pets and guard dogs. Be ready for a loud announcement whenever any visitor is at the door.

They will even bark if the only threat is the pizza guy, and will fight over the pizza afterwards. The best part: these cuties live up to 16 years due to a few genetic health issues. They age like fine wine!

5. Dachshund

Dachshund

According to the American Kennel Club, Dachshunds live up to 12 to 16 years. They are generally healthier than most large dogs. But don’t turn them into couch potatoes, or they might get overweight.

They are built like sausage-shaped sirens, low to the ground and high on alertness. These bold little hounds were once bred to hunt badgers.

They are generally low maintenance. With proper training and care, a Dachshund can live longer and spend its healthy life guarding your house like its royal palace.

6. Beagle

Beagle

Who can say that this sweet-faced dog can be a siren barker? Well, Beagles can be great guard dogs.

They are often seen as floppy-eared goofballs, but don’t underestimate them. They have one of the sharpest noses among small dog breeds and an extremely persistent bark.

Beagle Profile

Health-wise, they are champs. With minimal hereditary issues besides occasional ear infections and a love for snacks, they can stick around for 15 years. Just expect every mailman, squirrel, and even wind to trigger barking!

7. Miniature Schnauzer

Miniature Schnauzer

One of the few dog breeds with a beard, the Miniature Schnauzer. They look like they pay taxes and give advice to everyone in the neighborhood, but in the best way.

This dog takes guarding very seriously, barking at threats, real or imaginary. But that loyalty is what makes them great pets for families who also want a watchdog. They are one of the most intelligent dogs (and their wise appearance is proof of that!).

That Are Natural Intruder Detectors-01

They are sturdy, low on genetic health issues, and generally live up to 15 years with good food and exercise. Their wiry coat makes them look high-maintenance. But the real challenge is convincing them your cousin is not an intruder!

8. Miniature Pinscher

Miniature Pinscher

The Min Pin is a tiny dog and one of the longest living dog breeds. With an active lifestyle and routine veterinary care, they can live up to 12 to 16 years.

They are not just a cuddle bag but also a security alarm system that keeps you out of trouble. It may be a small breed, but it is terrifying and intimidating.

These dogs are confident and require consistent training with positive reinforcement. You don’t get past a Min Pin without being announced like a royal visitor, or a potential threat!

9. Pomeranian

Pomeranian

Fluffy? Yes. Fierce? Surprisingly yes! The Pom might look like it is a walking cloud or a dog angel, but it has the heart of a lion and the bark of an old, angry man.

These little furballs are sharp, alert, and weirdly obsessed with guarding their home (and their favorite person: you).

Pomeranian Profile

Health-wise, they avoid major structural issues due to their petite size. Their main health concern is their teeth, according to the Pomeranian Blog. But with proper dental care, it can be avoided. This can help them become the oldest dog in your household with a life span of 16 years!
