Whether you’re after a dog who can protect your home, loved ones and/or your business, the best guard dog breeds are well worth checking out. Most guard dogs also have a commanding presence, and many are often born with the natural instinct to protect the home, people, or business they are guarding.
It probably comes as no surprise to hear that guard dogs typically have a range of characteristics and qualities that make them good for warding off unwanted visitors. They're not shy of being vocal – just like the loudest dog breeds – especially when it comes to signs of stranger danger.
That being said – as is the case with all dogs – guard dogs will need proper training, the right care, and a strong bond with their human parent and family from the get-go. If housed incorrectly and not well looked after, guard dogs can rapidly cause destruction.
To help you decipher which loveable dog is the perfect match for you, we’ve rounded up the best guard dog breeds, known for their defending and protecting qualities.
Best guard dog breeds
1. German Shepherd
It probably comes as no surprise to hear that the German Shepherd tops our guide to the best watchdog breeds around. A favorite of the police, this breed tick all the boxes of brilliant guarding skills. They are easy to train, fiercely loyal, have amazing stamina, and are great under pressure.
Couple this with their strength and size, and this is the perfect mix for warding off any potential home invaders. But alongside their guarding traits, they also make for a brilliant pet who loves to play, so the perfect blend!
2. Cane corso
There are no prizes for guessing why the cane corso makes for such a good guard dog. At around 26 inches tall, they may not be the biggest dog breed vertically, but they are incredibly muscular and powerful animals.
With their Italian roots, the cane corso was originally bred as a fighting dog to protect Roman soldiers, and its name comes from the Latin word for ‘bodyguard-dog’. Therefore, guarding is quite literally in its name. But it’s also a docile fur friend until called into action.
3. Akita
Blending brains with brawn, the Akita might not look intimidating. But long, long ago, these Japanese dogs were bred to stand by the side of Japanese royalty and keep them safe from enemies.
So, it’s fair to say that this breed has protection qualities instilled into its every being. That said, nowadays, these friendly-looking dogs tend to be incredibly inquisitive and suspicious animals.
This makes them the perfect breed for alerting you to any danger they sense. So if you aren’t keen on a big, powerful guard dog, then the Akita may be the one for you.
4. Bullmastiff
A natural guard dog, the Bullmastiff is perhaps one of the first breeds that come to mind when you think of a four-legged protector. This breed has a very strong bite force as it’s estimated to be at around 550 pounds per square inch – which is around three times higher than the average dog.
Originally bred to protect game and large estates in the English countryside, this natural watchdog instinct is still present today. If properly trained and socialized, however, a Bullmastiff can be gentle and laid back with its human parents.
5. Doberman Pinscher
Bred in the 1800s by German tax collector Louis Dobermann, who needed a pooch to protect him, the Doberman Pinscher features in our guide to the best guard dogs for more reasons than one.
Its mighty size, sheer power, and quick speed are just some of the attributes that make this breed perfect for protection duties. But, couple this with its alertness and intelligence, and you’ve got a recipe for a fur friend that has great guarding dog abilities, with little training necessary.
Nowadays, the Dobermans' naturally aggressive trait was bred out of it, making them highly affectionate dogs for the family while also retaining the ability to protect. So, what’s not to love?
6. Komondor
We know what you’re probably thinking: a corded Komondor as a guard dog? Surely not!
But its unassuming nature and super loud bark are what set this unexpected ally against intruders. This Hungarian breed is a brilliant sheep herder – and this livestock herding quality is what makes the Komondor an innately protective pooch.
So, if you’ve got children you want to keep a watchful eye on, consider a Komondor a trusty sidekick that’s happy to take on the challenge.
7. Giant Schnauzer
Say hello to the Miniature Schnauzer’s bigger cousin! In days gone by, the Giant Schnauzer was bred to herd cattle, so they are naturally courageous animals capable of standing their ground against larger creatures in the animal kingdom.
But the same goes for those in the human realm. Strong and intelligent, these creatures take training in stride. So they’ll quickly learn which visitors are welcome and which aren’t. Therefore, they’re one of the most dedicatedly loyal pets you can welcome into your home and they are bound to grab attention with their iconic facial hair – as does any dog with a beard!
8. American Staffordshire Terrier
With a reputation for aggression (due to bad owners forcing them to fight), the muscular-framed and strong-jawed Staffy often gets misunderstood.
Naturally, American Staffordshire Terriers are incredibly protective of their owners so they score top marks when it comes to their guard dog skills. But good training is essential in keeping them under control when they feel they need to step up and keep you out of harm's way.
9. Rottweiler
Just like the American Staffordshire Terrier, the Rottweiler has a reputation for being an aggressive dog breed. But when given the proper training and raised with a family, traits like loyalty and affection come to mind.
The reason why we’ve included Rottweilers on this list is that they are inherently wary of outsiders. But if you take your time introducing them to friends and family, these intelligent and quick learners will be able to understand and remember who is a threat and who is a foe.
So, as long as you put in the effort to train and socialize them early, these protective abilities can make these muscular dogs brilliant guard dogs.
10. Rhodesian Ridgeback
With their strong stature and sizable frame, the original purpose of a Rhodesian Ridgeback was to hunt lions – so you can rest assured the average intruder won’t be too much of a threat for this protective breed.
Originally bred in Africa, Rhodesian Ridgebacks are fearless and natural protectors. They have the incredible ability to switch from a loving pooch to a furious guard dog in seconds.
Another quirk about this dog? They don’t tend to bark just because they feel like it. But when they do, you’ll know that there’s a problem.
11. Dogo Argentino
Weighing between 70 and 100 pounds – as long as you train these pups from an early age and provide them with lots of daily exercise – Dogo Argentinos can make for a brilliant guard dog.
This breed was originally bred to hunt big game. So much so that they are capable of taking down wild hogs up to six times their size! Therefore, guarding your loved ones will seem like light work.
Of course, as is the case with many other guard dog breeds, you will need to assert authority from the get-go, otherwise, they won't respect you or listen to your important dog cues.
12. Great Dane
Great Danes are often depicted as guard dogs due to their impressive size. But there is much more to this breed than their seriously impressive and imposing stature.
The origins of these large dogs, which were initially bred by German nobility for hunting and guarding. Today, Great Danes are known and loved for their caring, noble, and loyal personalities. They are also a brilliant mix of patient and protective, making them ideal for keeping around young families.
Like many other dogs, a Great Dane can become defensive when threatened, and while displays of this are rare, if trained well, they represent an obstacle for any menace.
13. Great Pyrenees
Hailing from the Pyrenees mountains, this breed of dog was the loyal companion of shepherds who needed a tough breed that could look after flocks of sheep in chillingly cold environments no matter the time of day or night.
Therefore, this breed is known for waking up during the night. Of course, being a night-owl isn’t normally welcomed by dog owners. But it will have the effect of deterring potential burglars.
14. Dogue de Bordeaux
Also known as a French Mastiff, the loveable Dogue de Bordeaux (which shot to fame thanks to the Tom Hanks movie Turner and Hooch) was bred as a guard dog for centuries.
Today, this big and wrinkly dog breed has a sweet disposition. For example, they are often named as one of the biggest drooling dogs, and although they may look like gentle giants, they are naturally protective and loyal to their family and territory. Therefore, they can be incredibly effective guard dogs.
15. Boxer
High on energy, packed with athleticism, and having a softer side, boxers are incredibly versatile dogs. They are a naturally protective breed, so they are used as service dogs by police forces for patrol and drug detection. They also also considered to be a good breed for emotional support.
Therefore, in a domestic setting, if properly socialized and trained, Boxers can make great guard dogs as they can form strong bonds with their family members. Plus, parents will be pleased to know that they are especially protective of kids.
They’ll also alert you to sounds and tend to confront intruders with their barks and bodies rather than their bites.
16. Belgian Malinois
Heard of the Belgian Malinois? Similar to a German Shepherd, this strong and well-muscled pooch is one of the best tracking dogs.
In more recent times, this protective, loyal, and very alert breed is one of the most popular breeds used by the police and military.
However, just like their German counterparts, Belgian Malinois require consistent training in order to ensure they are well-mannered and happy. Either way, under the right tutelage, they make for great companions and guard dogs.
17. Tibetan Mastiff
Back in the day, large guardian breeds like the Tibetan Mastiff were bred as guard dogs for property and livestock – and they still perform that role today.
They have strong territorial instincts and are highly intelligent, all of which are brilliant traits for protection. They are also often reserved when around strangers. But they are protective of their family and home. If trained properly from puppyhood, they are one of the best guard dogs you’ll come across.
18. Australian Shepherd
Known and loved for being a herding breed, the Australian Shepherd joins our list of the best watchdog breeds.
However, a fact about Australian Shepherds is that they are technically bred to be watchdogs, not guard dogs. So, if you want them to exhibit more guarding behaviors, you'll have to train them to do so.
19. Boerboel
Confident, calm, and coming with a protective nature, the boerboel hails from South Africa, where they work tirelessly to protect remote homesteads from predators. So, it’s no wonder they are often depicted as one of the best guard dogs.
Boerboels have a bright nature and are eager to learn, which makes them easy to train, and they are hugely devoted to those they love. Their highly intelligent nature and training and socialization needs mean that they aren’t the most suitable breed for first-time owners.
However, if you're able to be firm and quickly establish your place as leader of the pack, this affectionate dog will have a hard time leaving your side.
20. Beauceron
If there was a prize for a breed of dog that takes its role as a guard dog seriously, the Beauceron would win every time. Brilliant at herding, super smart, and good-spirited, the powerful and faithful beauceron is an incredibly loyal breed of the dog kingdom.
This perfect concoction of qualities makes this breed a brilliant guardian for you and the kids. However, just like the boerboel, this breed isn’t for first-time dog parents. Generally speaking, this breed is quick to exert their dominance and they’ll do so if they’re not trained or socialized.
21. Catahoula Leopard Dog
Just look at this beauty. One of the fastest dog breeds, the state dog of Louisiana (where it originated) is instantly recognizable thanks to its varied coat and eye color pattern.
But it’s not just their outward appearance you’ll fall in love with. Alert, wary of strangers, and coming with strong protective instincts, the Catahoula Leopard Dog makes for a brilliant protector, too.
22. Staffordshire Bull Terrier
More informally known as a Staffy, a Staffordshire Bull Terrier is a mix of a Bulldog and terrier breeds, and it was originally bred for dog fighting in the 19th Century.
Due to this, the Staffy often gets a bad rap. But if trained correctly and socialized as a pup, this breed can be a very loyal, calm, and protective dog, and today, these pooches are considered great family or companion dogs.
23. Bull Terrier
Coming with a muscular frame, loud bark, and strong physique, Bull Terriers can make for brilliant guard dogs. That’s not to say that they don’t have a playful and mischievous side, however.
Known for being one of the most comical fur friends, Bull Terriers have a very unique look with their long egg-shaped heads.
It’s worth knowing that while today, they are known as affectionate and endearing family dogs, they will need early socializing and lots of exercise.
24. Bouvier des Flandres
You might not have come across this herding dog breed before. Not only is it one of the best farm dogs, but along with ticking all the guard dog must-haves – they have an inherent protective nature and can be intimidating to look at – thanks to their thick fur and heavy bones, they are also one of the best dog breeds for cold climates.
The Bouvier des Flandres hails from Belgium and was originally used to herd livestock. Nowadays, this calm dog breed is loved for its ability to train easily, impressive hard-working nature, and affectionate persona.
25. Puli
With their dreadlock hair, the puli is perhaps best known as one of the most unusual dog breeds.
Often black, although you can find white, apricot, or gray colored pulis, these dogs might look slow and steady, but they are deceivingly fast. They also have the brilliant ability to change direction quickly, so they are agile, and they are naturally protective of their owners and home.
26. Chihuahua
Any Chihuahua owner will know that no one is getting in or out of the house without you (and your fur friend) knowing about it. That’s because this small, loyal, and very vocal breed is wary of outsiders.
Of course, their toy-size stature might not necessarily deter visitors, but their bark might. Therefore, they can make for brilliant guard dogs; as they might be small in size, they are big in personality.
27. Caucasian Shepherd Dog
As seen with the Caucasian Shepherd, it’s entirely possible to be a serious guard dog and a soft and playful fur friend, depending on who they are around.
Described as fearless and bold, the Caucasian Shepherd makes for a brilliant guard dog both inside and outside the home. No matter whether they’re guarding livestock or your four walls. But when they’re around their human pals, they’re soft, devoted, and kind. The perfect blend, if you ask us!
28. Estrella Mountain Dog
The Estrela Mountain Dog is a large-breed dog that’s also one of Portugal's oldest livestock guardian varieties. This strong pup hails from the Estrella Mountains, where they protected flocks of sheep and became loving companions of remote shepherding families.
Therefore, with strong watchdog roots, these loveable breeds are very loyal to their human family, protective and they are wary of strangers.
29. Saint Bernard
Standing at up to 28 inches in height, Saint Bernards have a deep bark, natural protective instincts, and loads of strength, which makes them a brilliant deterrent to would-be intruders.
They are also fiercely loyal toward their human family and kids and very loving.
30. Appenzeller sennenhund
This Swiss breed of medium-sized herding dog is another dog that has natural guarding instincts. They can also add agile, alert, and muscular to their profile.
And the appenzeller sennenhund is believed to be one of the most intelligent dogs, too – all of which makes them brilliant working dogs, no matter whether they are being put to work on the farm or guarding your four walls.
31. Anatolian Shepherd
Along with being one of the biggest droolers, the Anatolian Shepherd has qualities that make it one of the best guard dog breeds for maximum protection.
For example, they are bold, confident and have strong protective instincts instilled into every fiber of their being. Anatolian Shepherds, which hail from Turkey, are also highly territorial.
They are, however, very devoted to their human family and hugely loving. So, if you’re looking for a hard-working pup who’s intelligent, independent, and protective, you’ll find it in an Anatolian Shepherd.
32. Chow chow
They might look fluffy, friendly and full of life, but the loyal chow chow was originally bred in China to be a guard dog, guarding royal palaces.
So, while you might not have a palace to protect, chow chow dogs still have a protective role instilled into their every being. Therefore these natural guard dogs will be fiercely protective of their home, along with the family they are looking after.
