19 Most Dangerous Dog Breeds in The World

ByThePetster Team

It is difficult to tell if there are some specific breeds or varieties of dangerous dogs. The way that a dog reacts and turns out depends on how the dog is trained and raised, how he is treated, and the conditions in which he lives.

That being said, there are some breeds and varieties of dogs that are more prone to showing aggressive behavior than other breeds. This does not mean in any way that these varieties are going to present themselves as aggressive dogs with a mean streak.

It only implies that if these dogs are dealt with poorly, they will be more likely to evolve contentiously and may become more brutal than other breeds of dogs. Under the right conditions, these dogs of these Breeds can be loving, caring, happy, family pets.

According to the study conducted by The Journal of the American Veterinary that took place over 20 years to recognize and have a better understanding of the breeds which stand out to be the most dangerous varieties based on violent behaviors and bite fatalities.

1. Labrador

The Labrador breed is generally considered a friendly, easy-going, and lovable dog breed. If these dogs are not raised and treated well with love, however, they may become very dangerous. In the light of statistics shared by the Merritt Clifton Dog Bite, during the years 1982 and 2014, there were as many as 56 attacks that resulted in painful and serious injuries. Out of these nearly 17 were children.

Also, this breed is known for causing just one death during this period. In 2011, a boy nearly three years of age was mauled by a dog belonging to this breed which resulted in very serious facial injuries to the boy. As with any dog, it is the responsibility of the dog’s owner to make sure that their dog is given proper attention and is loved, properly trained, and properly cared for. Proper care may stop him from doing a deadly attack.

2. Cocker Spaniel

It is shocking to hear that, but this dog breed belongs to the varieties of dogs that may prove to be dangerous. At first sight, and if he is trained, raised, and treated well, he will make a great and lovable family relationship. Dogs of this breed are, however, very sensitive and emotional. Because of this trait, poorly trained dogs belonging to this bread may tend to attack.

In the light of a study done by JAVMA, the Cocker Spaniel is known to be responsible for at least 59 fatal attacks on people during the last 25 years. In the year 2016, an old-aged man in Jacksonville, Florida was attacked by a group of stray dogs, and at least one of those dogs was recognized as a Cocker Spaniel. The man couldn’t make it and he passed away.

3. The Bullmastiff

The Bullmastiff seems to be a very large, and very muscular dog. The Bullmastiff may weigh up to nearly 130 pounds and he may grow as tall as about 27 inches. Unless these dogs are very well trained, well treated, and well behaved, they may behave violently. Poorly trained and if not raised with proper attention dogs belonging to this breed may become very unpredictable and sometimes may become violent.

During the year 2014, a boy nearly 13 years old, belonging to New Jersey was attacked by a Bullmastiff and he was seriously, rather fatally injured. Another boy was also known to be attacked by a Bullmastiff and he was also fatally injured.

In the light of the statistics shared by the Merritt Clifton Dog Bite, there were at least 111 attacks during roughly 14 years. Out of these numbers, at least 46 were children and nearly 63 of the attacks proved to be fatal. With proper care, proper attention, and training, however, dogs belonging to this breed can make excellent family pets.

4. Tosa Inu

This breed is known to be a dangerous breed of dog and it is also known to be the fighting dog’s breed. This breed is also very rare. Being a very harmful dog variety, it has been outlawed in many countries incorporating the UK, New Zealand, Denmark, Norway, Hong Kong, Australia, and many other states. The main reason for its ban was due to an increasing number of attacks on many people, most of them being children.

Almost twenty years ago, the number of attacks was greater and was about in the thousands. Since they have been banned from owning one of these dogs and since there are almost no breeders left, in the light of statistics of ASPCA, there was only one attack reported by this breed during the last three years.

5. Malamute

The Malamute dogs are usually mistaken for the Husky. These dogs are huge, and they may weigh approximately up to 85 pounds. These dogs seem to be passive and they can make outstanding work dogs. Similar to the Husky, the Malamute breed is famous for pulling sleds in the blistering cold.

Due to their huge size, they have not proved to be the best pet to have for your young children. In the light of studies done by JAVMA, this breed was seen to be responsible for at least 12 fatal attacks over 20 years.

In February 2014 in the UK, a citizen’s six-month-old daughter was attacked and killed by the family’s Malamute dog. On the other hand, in Cornwall, UK, a man was walking with his family Malamute when a “pit bull-like” dog attacked him and his dog saved his life.

6. Saint Bernard

If you have seen the Beethoven movies at least once in your life, you can remember Saint Bernard as an intelligent, protective, caring, and loving family pet. This is a genuine thing. This breed of dog comes from the Italian and Swiss Alps and it is very popular for its ability to rescue hikers who may be stranded in the snowy mountains.

But don’t confuse yourself by thinking that these dogs can only be loving, while such dogs may behave friendly, protective, and caring they may also become very territorial and violent. If you want to keep your Saint Bernard breed dog from rising and representing territorial, violent, and aggressive behavior, you need to start socializing him with strangers, making him comfortable with other people and other animals at a young age.

As long as these dogs are trained properly, they can behave like great and friendly dogs. If the dog belonging to this breed isn’t, he can be potentially violent, aggressive, and dangerous due to his very big size and aggression. The average weight of this breed can be between around 140 to 260 pounds.

The largest dogs belonging to this breed can reach a maximum of about 310 pounds. If your dog is trained and taught to be aggressive, he can do a great amount of damage and fatality because dogs of this breed weigh so much. In the light of JAVMA’s study, there were just 7 fatalities from a Saint Bernard dog attack during the 20 years.

The number of attacks may be much more, and many went unreported. In July 2016, a Canadian woman was stepping at a bus stop when a Saint Bernard at the end of a harness came to ambush her. In the light of reports and pieces of information gathered from victims, she didn’t provoke the dog even when it attacked her and she ended up losing a lot of blood. She acquired 40 stitches and her patella was broken.

It is not known what type of home life and training the Saint Bernard dog had, however, it was approximately the size and the strength of a huge dog that made it impossible for its holder to pull and maintain the dog off of the sufferer.

7. The American Bulldog

The American Bulldog is incredibly huge and muscular also, he has a stocky build. He can weigh as much between around 60 to 120 pounds, he maintains a great deal of power in his muscular body. This breed was originally bred to work on a farm where he could help his owner go catch and hold cattle and wild boar. He was made to also kill the vermin that tried to take over and destroy the farm and he would protect his owner’s property. Today, he is considered a family dog.

On the other side of the story, this dog has attacked people but in May 2012, an American BullDog guarded a woman and a sleeping child when an intruder entered the home.

8. The Great Dane

The Great Dane is an incredibly huge dog. He holds the record as he is the tallest dog in the world, having a height of around 44 inches.

If these dogs are not trained and taught properly, their huge size can make them very dangerous. If the dog becomes aggressive and violent and he has a weight of up to 120, you could find yourself in an incredibly dangerous situation.

9. Akita

The Akita is native to the mountains of Japan. It is a very strong, bossy, dominant, and independent breed. They can be very territorial around strangers. Dogs belonging to this breed are very muscular dogs and they can weigh around 100 pounds. Considering their size and their territorial behavior, they can be very dangerous if they are not properly trained and given attention.

In June 2014, an Akita who was properly trained saved his 5-year-old owner from a bear attack, also there have been some cases reported in which dogs of this breed harmed people.

10. Boxer

The Boxer dogs are not normally aggressive. They are typically very playful, intelligent, loving, and energetic dogs. They are also very headstrong. The only cause that these dogs are known to be dangerous is that there were around 48 attacks reported that involved dogs of this breed from 1982 to 2012.

However, in Goshen Township, around 2010, a home caught fire. It was the boxer belonging to that family who saved his owner from catching the fire, doing this he risked his own life. He also did recover from those injuries he suffered, but he had to fight for his life. These dogs can be friendly, loving, caring, loyal, and heroic under the right conditions.

11. Wolf Hybrid

The dogs belonging to the category of Wolf Hybrid are a cross-link between a dog and a wolf. Due to the genetic nature of a wolf, the dogs belonging to this breed can be very unpredictable. A few of these dogs acquire more traits of a dog and their behavior tends to be more towards that of a dog, while other few acquire more traits from the wolf and their behavior tends to be more like that of a wolf.

Some of these dogs can be very calm, caring, non-aggressive, and docile. Unfortunately, a greater percentage of the dogs belonging to the wolf hybrid breed is more likely to be violent and dangerous and they tend to attack humans and small animals.

In the list of the study and research of different dog attacks, JAVMA listed about 14 fatalities and at least 364 attacks. The total number of attacks may not be exactly correct, as some dog bite incidents were not reported. In May 2013, a neighborhood Wolf Hybrid attacked a 5-year-old boy, causing him serious injuries. In 2009, a Wolf Hybrid attacked a sleeping baby from his crib and the baby died of his serious injuries.

Many people blamed the dog, supposing that he is partially a wolf. Others blamed the owners of the wolf hybrid for not carefully and properly training and teaching their dog.

This breed is the only dog breed on this list that can become violent, aggressive, and dangerous, even under the best conditions, just since he has the genetic makeup of a wild animal.

12. The Husky

The dost belonging to Husky may become dangerous to humans, however, they can be especially killers and attackers to smaller animals. They are very strong and huge dogs and are specially bred for pulling sleds through the snow. They have a great predator instinct, which can make them extremely dangerous at times.

In the light of statistics developed by the National Association of Dog Bite statistics developer, during the past 15 years, the Husky dogs were responsible for at least 15 fatal deaths. With proper teaching, proper upbringing, and training, however, you could safely bring a smaller animal into the home but not the bigger one.

These dogs aren’t only violent and dangerous to living things, they can be very aggressive and destructive in your home. If the husky gets bored while its owners are away, the one could come home to chew up the furniture and a huge mess just done by this creature to get rid of its boredom and due to its aggressive nature.

13. The Rottweiler

The Rottweiler is a very huge-sized and massive dog. They can weigh up to about 130 pounds and most have extremely large and are pure muscles. This dog is considered to be very aggressive and dangerous because he has a genetic predisposition to protect, fight, attack, and herd. Not all of these dogs belonging to the Rottweiler breed are savage beasts.

As with many breeds, these dogs can have a bad reputation due to abuse, neglect, carelessness, lack of attention, lack of socialization, lack of training, a poor environment for the upbringing, and being cared for by irresponsible owners. According to the statistics proposed by Merritt Clifton Dog Bite, the Rottweiler was responsible for at least 535 dog attacks between 1982 to 2014.

14. German Shepherd

Most German Shepherd dogs are caring, loving, and friendly. They are usually intelligent, smart, vigilant, protective, alert, and fearless. Due to these remarkable qualities, these dogs are mostly used with police K-9 units.

While these dogs can make lovely family pets, they need to be properly cared for, taught, socialized, and trained from a very young age. They can become very protective and caring of their owners, their family, and their home. Because of this quality, they can be fatal and dangerous. If a friendly stranger who is also a stranger for the do comes into the home, a German Shepherd who has not been properly taught and trained can attack.

This can make them violent and dangerous. If a stranger comes into the home who is planning to harm, these dogs become violent, aggressive, and protective and then they get attacked. Overall, these dogs can be aggressive and dangerous if they are not properly trained.

15. The Bull Terrier

The most distinctive feature of the Bull Terrier that differentiates it from other dog breeds is its large, massive and egg-shaped head. He is also recognized for his incredibly huge muscular body. The Bull terrier dogs have gotten a bad reputation in the past, due to being not taught properly, not cared for, treated badly with cruelty, mistreatment, abusive behavior, and trained to attack.

These dogs are not actually and technically dangerous towards humans if properly trained, they are not bred to attack or guard, however, they can be attacking and dangerous to smaller dogs and animals. This is due to the reason that they have a strong instinct and urge to hunt their prey.

If they cannot learn to get rid of this urge, they can become violent and aggressive to these smaller animals and can cause them serious wounds and injuries when they attack. This breed is not very huge but it can weigh up to 65 pounds and he is swift and tough. If he is properly trained, taught, loved, and cared for, he can be a great and lovely family pet, even in homes and with small animals.

16. Gull Dong

The Gull Dong breed is a cross-link between a Bully Kutta and a Gull Terrier both being different dog breeds. These dogs are recognized as being incredibly strong. They were originally bred as protective and fighting dogs, and they are said to be very difficult to control, violent, harsh, and very aggressive.

If someone wants to own one of these dogs, they would need to get the dog professional training started from a very young age. He can weigh so much approximately up to 140 pounds and this is a lot of weight to put behind and the attack can not be inhibited once done.

17. Pitbull

The Pit Bulldog breed is considered to be one of the most dangerous dog breeds in America. In the light of studies and research done by dogsbite.org, between 2005 to 2014, approximately 203 Americans were killed to death by a Pit Bulldog and 305 people belonging to America were seriously injured and wounded after a mauling.

These dogs were originally bred for baiting bulls and guarding hunters against bears. These dogs are incredibly huge and muscular. Most of the Pit Bulldogs don’t have even an ounce of fat on them. They are huge and pure muscle.

These pit bull dogs are certainly decent looking and very cute, however, numerous Pit Bull parents/owners make shifts to the dogs to give them a mean, tough and intense look. This is part of the reason that people get so scared of their looks and are usually so afraid of these dogs. The other reason is the way that the dogs are trained, and treated.

Many unethical criminals out there train and teach them in such a way to use these dogs to fight with each other for money and profit. To train them for criminal purposes, they starve them, mistreat them, beat them, abuse them, and torture them.

It is one of the inhuman and cruelest crimes imaginable.

18. Tibetan mastiff

It’s believed the Tibetan mastiff is powerful enough to slaughter a tiger easily, and when you see the appearance of this towering breed, it’s not difficult to believe this fact.

It is about 26 inches tall and has a huge body and it is so massive, weighing up to 150 pounds, the Tibetan mastiff dogs have abundant, furry coats.

Although these dogs are highly guarding, fighting, and protective, they are intelligent and smart and they also show restraint and signs before attacking, so they are not like a loaded weapon aggressive to go off. If someone feels capable of asserting his authority over this dog, the Tibetan mastiff will make for a rewarding if challenging dog. You won’t have any worries about your house or territory being burglarized with him staying inside either!

19. Kangal

Kangal has a very strong protective streak, he will protect his owner rather than outright attacking and aggressive threats. In this sense, they can be recognized as more of a guarding and protecting dog than an attacking and ruthless aggressive dog.

Such dogs have the strongest and most killer bites in the canine world, rated at around 743 PSI (pounds per square inch). Nobody should be in disarray with a Kangal or they are likely to face worse circumstances.

The Kangal breed was originally bred to guard the sheep. Stable on thin and very tall front legs, this dog looks more violent, imposing, and intimidating than the average canine.
