These Are Some Of The World’s Most Dangerous Dog Breeds

While you probably know exceptions to the breeds on this list, some dogs are more dangerous simply based on their size and force of their jaws.

Dogs have long been known as man’s (and woman’s) best friend. Canines are loyal and lovable, and they often provide comfort, protection and other services to their human counterparts. However, they can also be dangerous.

Depending on the animal’s upbringing, temperament and circumstances, any dog can be a threat. Even small dogs might bite someone. In fact, chihuahuas sink their teeth into vets more often than any other type of pooch.

But certain breeds can cause greater harm simply because of their size or the force of their jaws. Based on the damage they can do, these are some of the world’s most perilous pooches, in no particular order.

St. Bernard

These giant dogs from the Swiss Alps are famous for rescuing people from the snow. They are generally intelligent and friendly animals. However, they can become aggressive in certain situations, especially if they are not properly socialized. Due to their enormous size, this can mean trouble.

Great Dane

Standing as high as 32 inches at the shoulder and taller than an adult human when on their hind legs, Great Danes tend to be sweet, friendly and patient with children. However, they are alert guard dogs as well. Great Danes have even caused fatalities.

Bull Terrier

Depending on your age, these pups might make you think of either Spuds MacKenzie or Bullseye, the Target dog. Bull terriers are affectionate pets that love to have fun. Although the unique-looking dogs are not especially large, they are quite muscular and were originally bred to be champion dog fighters. Because of their strength and strong prey drive, they should be watched around children and other animals.

Siberian Husky

These lively and striking dogs are loaded with energy and ready for playtime. Although they are friendly, outgoing and eager to please, they can also be stubborn and require a great deal of training and attention. Studies show Huskies are among the most dangerous dogs, particularly when there is a lack of structure or training.

Chow Chow

This East Asian dog breed is one of the most ancient still in existence. In northern China, chow chows are called Songshi Quan, which means “puffy lion dog,” and it is easy to see why, with their small ears and bushy “manes.” They also have powerful jaws like a lion, with a bite force of 220 pounds per square inch (PSI), and can become aggressive due to lack of socialization or an overprotectiveness of their owners.

Belgian Malinois

Often mistaken for a small German shepherd, these herding dogs are highly intelligent and energetic. Their nature makes them excellent guard dogs and police dogs. However, they can also be aggressive, especially with small children and other animals. They have a bite force of 195 PSI, as well.

Pakistani Bulldog

This strong, intelligent dog is known by several names, including bully gull terrier, gull dong and kanda. Pakistani bulldogs are smart, loyal and strong-willed, which means they need an owner who is a strong leader. Without proper, consistent training and a watchful eye, they can be quite dangerous.

Labrador

Labrador retrievers are consistently the most popular pet dogs in the United States. Perhaps this is why they are also responsible for a high number of serious biting incidents. While labs are generally very well-natured, lab owners should learn and watch out for signs of reactivity, such as fearfulness, frustration and even medical issues, that may cause them to bite.

Akita

Akitas tend to be big-boned and burly. They naturally have an imposing appearance and their quiet nature can add to this impression. Although they are affectionate with their favorite people, Akitas tend to be protective, wary of strangers and not especially fond of other animals. They can become dangerous without proper training and careful handling.

Doberman Pinscher

Dobermans are powerful and energetic, and they are excellent guard dogs. They are fiercely loyal to their human companions and will be affectionate and protective of children with whom they are raised. Their excessive energy and protective personalities can cause them to become irritable, aggressive and dangerous. Dobermans require a great deal of exercise, training and socialization.

Pit Bull

Intelligent, affectionate, funny and playful are all words that can be used to describe these dogs. However, these beloved pets are also responsible for a large number of injuries and fatalities, and even PETA advocates for all pit bulls to be spayed or neutered. Some experts believe the many pit bull attacks are because the dogs are increasingly popular, were bred for fighting and are often improperly trained, handled or treated.

Caucasian Shepherd

Also known as the Caucasian Ovcharka, Caucasian sheepdog or Kaukasische Schaferhund, these massive dogs can weigh as much as 200 pounds. Originally bred for herding and guarding livestock, the dogs are known for being powerful and confident. Because they are so large, strong and protective, they can become aggressive and dangerous when they are not trained correctly.

Boxer

Boxers are happy, playful, loyal and smart. They tend to be gentle with children and protective of their families. They can also be strong-willed and stubborn, making training a chore. However, proper training is a must, as they can become aggressive and have an extremely powerful bite.

German Shepherd

One of the most popular dogs around the globe, GSDs (German shepherd dogs) have been around for a little more than a century. They were the first service dogs, they often work alongside military and law enforcement personnel, and they thrive on protecting the humans they love. Perhaps this is why they are responsible for many injuries to people, including 19 fatalities over a 17-year period.

Rottweiler

This muscular breed looks like the beefier cousin of the Doberman. However, Rottweilers were actually bred to be draft dogs, hauling carts as well as guarding homesteads. They are active, intelligent and require a great deal of exercise and attention. Lacking these things, they can become aggressive, leading to potentially dangerous behavior, as they have a bite force of 328 PSI.

Kangal

This large sheepdog has its roots in Turkestan and comes from the mastiff family. Kangals are large and strong enough to ward off impressive predators, such as wolves and bears. Although they are protective, Kangals are also gentle and friendly. However, their size and bite force, which is reportedly as strong as 743 PSI, make them dangerous to anyone who threatens these gentle giants or anything in their care.

Bullmastiff

As the name would suggest, bullmastiffs were originally a cross between bulldogs and mastiffs. These big dogs can weigh more than 100 pounds and stand as tall as 27 inches at the shoulder. During the 19th century, gamekeepers bred bullmastiffs to stop poachers in their tracks. Although they usually form deep bonds with their people, a dog that is not socialized can be dangerous.

Wolfdog

A hybrid of a domestic dog and one of four types of wolves, wolfdogs are a controversial pet and are restricted in some states and cities. Wolfdogs may have fear-induced aggressive tendencies, which can be hard to predict or control. The hybrid dogs have a powerful bite force of 406 PSI.

Australian Shepherd

Aussies are highly intelligent, energetic and agile ranch dogs with a strong urge to herd everyone and everything. Because of their herding nature and tendencies to chase and nip, they should be watched around small children and other animals. They can also become aggressive, particularly toward strangers, so early socialization is vital.

Tosa Inu

Also known as a Japanese Mastiff, these dogs were originally bred as fighters in Japan. Fully-grown Tosa Inus can weigh up to 200 pounds and can pull about 3,000 pounds, making them a serious force to be reckoned with. While Tosa Inus can be calm and gentle, they are actually banned in the U.K. and several other countries because of their potential for aggression.

American Bulldog

Bulldogs were originally bred for farm work, guarding and fighting. American bulldogs can be gentle, loyal and affectionate pets when raised properly. However, the strong dogs can hurt small children inadvertently due to their sheer size.

Perro de Presa Canario

This mastiff’s name translates to “Canary Island catch dog,” and they are used to drive livestock or chase off (and kill) predators. These dogs typically weigh upward of 100 pounds and are extremely powerful. Socialization and consistent training are crucial for this breed, as poorly trained dogs have killed people.

Alaskan Malamute

Originally bred to be arctic sled dogs, malamutes are strong pack animals. Because of this, they require firm leadership and disciplined training from their owners. Without leadership, they might believe they are in charge and can become dangerous pets.

Cane Corso

A mastiff breed from Italy, the cane corso has been around for thousands of years. The dog’s name roughly translates to “guardian dog,” and they were originally bred to hunt, battle and participate in blood sports as well as guard people and property. Irresponsible breeding and training practices can result in dogs that are aggressive and dangerous.

English Mastiff

Large, strong and instinctively protective, English mastiffs are naturally low-maintenance guard dogs. The massive breed is generally gentle but is better suited for homes without small children. With a bite force of 556 PSI, they can do some damage with their jaws.
