the Best Guard
Dog Breeds

Updated 2022

Guard Dog Breeds take action, unlike watch dog breeds that are all talk (bark). The American Kennel Club suggests that good guard dogs be, "loyal, brave and extremely protective of their territory." I might also add, trainable, confident and reserved around strangers.

Watchdogs are very good at letting you know there is a stranger about, by barking, but they may not necessarily do much more. On the other hand, a guard dog breed will be prepared and equipped to defend its owner's property and life, if needs be.

Guard Dogs vs. Watch Dogs

Guard dog characteristics relate to many different types of dog breeds. Many watchdog breeds are ALSO capable guard dogs. 

So what exactly differentiates watchdogs from guard dogs? 

It is almost entirely the size and strength of the dog.

Owners of four pound Chihuahuas might argue that they dogs are brave and loyal, act confidently, but not always outgoing around strangers. Why aren't they in the list of best guard dog breeds?

It's because, although they will alert their owner to unusual activity by barking, they simply don't have the size and weight to intimidate an intruder, nor attack if required.

How did they become Guardians?

Some of the dogs on the list have been developed to be guardians and excel at the job because of their innate nature. On top of that, they can be trained to be even better guardians. Not only were they developed to protect people, but they were also needed for livestock protection. Livestock guardian breeds are alert, suspicious, and capable of taking on wolves and even bears.

Historically, people sometimes lived on isolated farms or ranches where their nearest neighbor could be miles away. Visitors were few and far between. Early settlers depended on dogs to alert and protect them if anyone came onto their property. A prime example of this is the Rhodesian Ridgeback.

In some areas of the world, people's lives and livelihoods depended on the dogs. These dogs needed to be able to take down the large cats such as snow leopards in Asia and the biggest and most dangerous predators on the African safari. Think Rhodesian Ridgeback, African Boerboel or Bully Kutta.

Beyond that,

most of the dogs that make our list have the right "look" that tells would-be intruders, "Don't mess with me." It could be their size, the color, their body posture. Or, it could be that people learn over time which dogs to stay clear of especially if their owners are not at home. The Cane Corso looks like the Mike Tyson of the dog world . . .

Personal Anecdote...

We were in the process of house hunting in a new community and one house was on our list of "must see."

Unfortunately, the owners had two large Doberman Pinschers in the front yard. Even though we had been given permission to enter the home, the Dobermans would have none of it. 

I think they might have killed my daughter who was three at the time.

Later in the week, we had another appointment to see the house and, this time, the owner was home. The dogs could not have been more friendly and gentle. 

Unless I had known better, I would have believed they were different dogs.

It should not come as any surprise that some of these guard dogs could also be called the most dangerous dogs in the world. 

Their fierce sense of loyalty, combined with their size and strength make them not only a brave guardian but a force to be reckoned with.

Recommended Owners for Guard Dog Breeds

Guard Dogs can make good pets for the right kind of owners, but these breeds should not even be considered for the first time or inexperienced dog owner.

Guard dog breeds are almost always independent and dominant and unless the owners can fulfill the role of Alpha Male, the dog could become more dominant than you!

Dog owners who do not have the time, energy, stamina or desire to socialize and train should not own one of these breeds. These dogs need ongoing training and socialization throughout their lives and that requires a significant time commitment.

The Best Guard Dog Breeds
from Around the World

Listed in alphabetical order. Due to variations between individual dogs, it is difficult to classify the best guard dogs only by breed. For example, an individual American Pit Bull Terrier may be a better guard dog than the much bigger Japanese Tosa, despite the weight difference.

You have to take into account how alert the breed may be, as well as how aggressive they may become when faced with an intruder. How intimidating they may appear. And then how brave they might be. And, finally, how much protection they may ultimately afford you when taking on someone who means you harm.

Akita Inu

The American Akita is a loyal, alert dog with a strong, muscular body build. The breed is well known for its intelligence, with many being seen performing in obedience trials. They are quick learners.

These dogs have energy to spare, and need plenty of exercise. They are not known for being particularly outward-going, and are reserved with strangers.

To some people, the American Staffordshire Terrier means only one thing - - PIT BULL - - and with that comes all the negative propaganda that has spread throughout the news at every level, prompting breed bands and high insurance rates.

To many, all they see is a vicious fighting dog that should be banned if not destroyed.  Just how much of this rhetoric is accurate of this breed? It is true that the American Staffordshire Terrier has suffered and gained a bad reputation. However, while they are strong, powerful, and courageous, they are not vicious.

Great Dane

These dogs were not bred specifically to be guard dogs (like the Dobermann or the Rhodesian Ridgeback). But their sheer size will act as a deterrent for most would-be intruders. For sheer size combined with protection, the Irish Wolfhound is probably a better bet.

Although they are not good watch dogs, once aroused they are virtually invincible. Bred to take on a wolf one-on-one, the Irish Wolfhound is immensely brave, powerful and agile.

Superb family members and relaxed around the house, the Irish Wolfhound has the motto "Gentle when stroked, fierce when provoked". As guard dogs they are without peer once stoked into action. Their sheer size, weight, power and bravery are the result of its breeding to take down the huge Irish Elk and then wolves in 1-on-1 fights.

But they are slow to react, and quiet by nature until they are stirred into action. This breed does not have a long life span, at around 7 to 8 years on avarage.

Kangal Shepherd

Kangal dogs are originally from the Anatolia region of Turkey. They were bred to be livestock guardian dogs, protecting flocks of sheep and goats at night from wolves, jackals and bears.

There is an important distinction between dogs that help a shepherd to herd animals, ie. move a flock from place to place, and dogs that protect the animals. These are livestock guardians, and they have to be big, strong, and ready to take on an attacker - but at the same time they must be non-aggressive towards their flock.
