Dogs have evolved alongside us to perform many types of jobs over generations, but guard dogs were among the first and most important. The scariest-looking dogs are the most effective at intimidating would-be intruders. Having the scariest-looking dog can prevent conflict before it happens, and there are plenty of big and wild dogs that fit the bill. Whether they are scary because of their strongest bite or simply because they bark loudly, these are the dogs you want to keep around. Some were originally bred from wild breeds for use as war dogs, while others were developed due to the need for strong workhorses on farms.
We should clarify that just because a dog breed looks scary doesn’t mean it’s inherently more dangerous than any other. In fact, dogs bred for guarding duties often need to be bred for dogs that look the most dangerous but are gentle with the household or livestock they are assigned to protect.
Like any other type of dog, these breeds require early and frequent socialization, tailored training, and enough exercise and mental stimulation to discourage aggressive and problematic behavior. With proper training and care, they can make excellent, well-behaved pets.
Here are the 8 scariest dogs by breed, along with information on what makes them valuable companions, as well as their ability to repel intruders.
1. The Scariest Dog in Pop Culture: The German Shepherd
You can at least partially blame Hollywood’s portrayal of German Shepherds in movies and TV. The heroic Rin Tin Tin was arguably the world’s most famous German Shepherd and the first big animal movie star, but German Shepherds are more likely to be portrayed as ferocious and barely restrained beasts – and German Shepherds are trained to Attacking police officers as part of their training is a metaphor that’s both for laughs and to create a sense of danger. While it is true that these dogs are often employed by the military and police, this is due to their general abilities as working dogs rather than their reputation as some of the scariest dogs around. Because while the German Shepherd’s large build and bark can deter intruders, these dogs are intelligent, quick to train, and fiercely loyal to human families.

2. The breed with the strongest bite: Kangal
The national dog of Turkey, the Kangal is another dog whose professional breeding as a herding worker has also earned it a solid reputation as both a defense against intruders and one of the strongest breeds in existence. In their native country, Kangals are often bred as outdoor dogs, but their gentle dispositions actually make them the preferred family pets. Kangals are loving and gentle at home and also tend to adapt well to long periods of time alone. But their reputation as one of the most aggressive breeds can be traced to the strength of their bite. Due to their large size and the design of their skulls, these dogs possess a bite force of over 700 pounds per square inch. That’s only one-fifth the bite strength of an alligator, but it’s still enough to make the kangaroo one of the strongest breeds.
They may be scary looking dogs, but after getting to know them here, you’ll love Kangal.
3. The Wildest and Most Unpredictable Dog: The Wolfhound
Many dogs have a reputation for being the most dangerous or intimidating because of their history as working dogs to the benefit of strong, burly canines, but the feral unpredictability of wolfdogs may actually be earned. These fearsome dogs are not a breed per se, but the result of a co-breeding of dogs and wolves. The most dangerous are those with a particularly high proportion of wolf blood, but the large genetic differences between the two subspecies can produce somewhat unpredictable results even after several generations of breeding. But these dogs actually tend to be shy around people, preferring to hide rather than let out the most dangerous barks.

4. Most Restricted Dog in America: American Bulldog
The Pit Bull gets its name from the fact that it was originally used in blood sports that could take the form of pit bulls or dogfights. Due to its reputation as one of the most aggressive and powerful breeds, nearly a thousand cities across the United States have passed legislation to ban or restrict the breed. But as public awareness of the real risks of owning pit bulls grows, many of the restrictions are being reconsidered. They may have the strongest bite force of any breed, but they have not been proven to be more dangerous than other breeds. That said, their history as pit dogs means they don’t always get along well with other dogs in the house.
As with any breed, Pit Bulls need proper exercise and socialization to do well, which you can learn more about here.
5. Strongest Breed: Rottweiler
Rottweilers have the strongest bite of any breed, but they are also one of the strongest in general. This is by design. Rottweilers are often used as butchers’ companions, handling everything from herding livestock to slaughtering, setting down any large bulls that might pose a danger, and pulling heavy carts full of meat to market. This no doubt explains the breed’s massive neck, strong frame and powerful bite. Properly trained Rottweilers can be loyal, playful, and friendly companions—but their large, powerful builds mean they can also be clumsy at times. As typical working dogs, they are happiest when they have a task to perform.

6. Fastest Guard Dog: Doberman Pinscher
With proper training, Doberman Pinschers can be one of the most loyal companions around—but that’s no surprise when you consider that they were bred with the express purpose of being guard dogs. More specifically, they were bred to protect game such as elk and deer on country estates from poachers. Their reputation as the scariest-looking dogs is partly due to the fact that they form very close bonds with their human companions and are otherwise cold to strangers or acquaintances alike. But if their reputation isn’t enough to deter intruders, the fact that they can run at close to 35 mph should do the job just fine. They’re also known for being one of the smartest breeds around, which means they can learn various commands with considerable ease.

7. Largest dog in the American Kennel Club: Great Dane
The Great Dane easily ranks among the largest dog breeds on Earth, with one member earning the honor of being the tallest dog in the world. Freddie stood an unbelievable seven-and-a-half feet tall when he stood upright, but he was actually a large, tame giant. This is actually standard for this breed. While they may have large bodies and a terrifying deep howl, these dogs require only moderate exercise and are very gentle with both humans and other pets. Originally bred to be a hunting dog, the average Great Dane will happily nap through the afternoon. But they can have a tendency to be bossy at times, so it’s crucial to establish a training routine with clear boundaries from an early age.
If you’re considering bringing a majestic Great Dane into your life, you can find all the basics right here.
8. Most aggressive dog: Cane Corso
The Cane Corso dates back to ancient Greek times, and it’s often seen as one of the most aggressive dog breeds in history. While they were indeed once bred to be war dogs, these Italian mastiffs have matured with age. In fact, Cane Corsi is known for being especially aware of the feelings of his companions. They were bred for various tasks on farms, but they are now likely to be used as therapy or emotional support animals. As far as his family is concerned, Cane Corso is overly loyal. This means that proper training may be needed to keep them from becoming too territorial.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
