20 Most Dangerous and Aggressive Dog Breeds

September 13, 2022

According to the Dog Bite Statistics

Dogs are affectionate, loyal, and often considered to be man’s greatest friend. Indeed, most of these friendly pets are dedicated to protecting our lives from things they consider dangerous. In the process, they might be aggressive towards strangers and, in some instances, may even attack.

The listed dogs are actually dangerous, without any exception. There are some breeds that have a higher likelihood of displaying aggressive behavior.

We didn’t put together this list to discourage people from owning any of these animals. Instead, it’s meant to inform owners and others about the dangers that could arise from interacting with an animal that’s not familiar to you. Apart from dog breed, there are many aspects that determine if dogs are a danger to you or not.

By the Numbers: Dangerous Dogs

How can we determine how much “dangerous-ness” a dog breed is? What are the factors we should be considering? There isn’t an exact method or 100% accurate method of determining the degree of danger a dog poses. Instead, we must take advantage of the information we have.

However, we evaluate these breeds as dangerous using two different statistics:

  1. How many human deaths (deaths) are due to this dog breed?
  2. How many of these attacks have been reported?

Aggressive dogs and attacks on human beings have been hotly debated topics from the very first dog domestication. In the 90s, the Centers for Disease Control & Prevention (CDC) took the decision to look into the evidence of these attacks.

They realized Pit Bulls were the most dangerous breed. Pit Bull was the most dangerous dog breed in the United States (between 1979 and 1996). In reality, Pit Bulls were involved in 60 fatal incidents, which is more than twice the incidents of the second-ranked Rottweiler (29 instances).

Of course, it’s not impossible to find exceptions in the context of many external factors that influence this. We’re not trying to define all dog breeds as aggressive or dangerous. It’s just objective information we can use to gauge the danger dogs pose.

Fatal Dog Attacks – The Report

Of course, these canines have engaged in dog-related attacks since the 1990s. Following where the CDC stopped, DogsBite.org also investigated deadly U.S. dog attacks (from 2005 until 2017).

The police documented the incidents and the victim’s age, the number of dogs involved, and the resulting punishment (if there were any). It’s troubling that Pit Bulls were responsible for 66% of all fatalities. Pit Bull is responsible for the majority of the deaths in the 13-year period. There were 284 deaths between 2005 through 2017.

In the second position, Rottweiler made up only less than 11% deaths from fatal assaults and a paltry 45 deaths. The reason for this is the numbers. Data tell us that Pit Bull is by far the most dangerous breed of dog worldwide.

Dangerous Dog Breeds Ranking

Notice: This dangerous dog breed list doesn’t include breeds that AKC doesn’t accept. Furthermore, there is no data that is accessible or sufficient regarding dog-related attacks in certain countries. That’s why there are many dangerous dogs around the globe.

Akita Inu Highlights: Courageous, Proud, Loyal

Akita Inu is considered to be one of the most terrifying guard dogs that come from Japan. They’re possibly next to those of the Tosa Inu, breeds that were originally developed to be combat dogs. In the present, the Akita Inu is the dog breed that is considered the national emblem of Japan.

They’re among the most popular guard dogs in Japanese families. They’ve been given as gifts by Japanese royals. For instance, the prime minister Shinzo Abe has given puppies Akitas several times.

They’ve been given to all kinds of people, all the way from Olympic silver medalist Alina Zagitova to Russian President Vladimir Putin. It’s no secret that The Akita Inus are a big deal in Japan.

They are independent and confident and are bred to provide world-class security to any household or home. However, they are cautious and distant from strangers. They’ll often view people they don’t know in a negative light as “dangerous,” whether they are or not.

A dog of the force and sheer size of Akita is sure to cause some harm. In many instances, they can easily harm or kill an individual, either accidental or otherwise. This is why their instincts to protect take over, and they’ll most likely fight to defend.

1. Doberman Pinscher

Doberman Pinscher

Highlights: Vigilant, Devoted, Brave

It is believed that the Doberman Pinscher is a fearless dog belonging to the working class. They’ve been around for a long time as protectors and guardian dogs. They were actually developed to guard. This is why they’re a great aid for police officers and are considered to be the best security guards in the homes.

There is no doubt that Dobermans are strong dogs. Dobermans outshine other dogs at 28 inches high and weigh as much as 100 pounds. They have many strength levels and have to be taught as early as possible.

The main concern when it comes to raising a large breed of dog is the capacity to implement obedience training effectively. They are actually smart dog breeds. But their dominance and size make them challenging to handle for a novice dog owner.

A lot of owners say that their Dobie is loyal, respectful as well as energetic, active, and brave. All of these characteristics are valid if they’re properly socialized and trained. If they aren’t, it could lead to a destructive and dangerous dog.

Any potential or new owners should be aware that maintaining the health of a Doberman requires extra care. People who didn’t take the necessary steps are likely to be those with Dobermans who contributed to the deaths.

Yet, this Doberman that brutally slew the baby of its family has been described by its owners to be “sweet” and “kind” and “kind” – so you won’t know. Make sure that your children are away from large dogs, regardless of how much you love the dogs. This could easily turn into an unintentional situation.

2. Boxer

Highlights: Bright, Social, Energetic

Most Boxers are dominant dogs and show aggression toward other breeds of dogs. In certain situations, they may show aggression towards humans too. However, Boxers aren’t generally aggressive. They have plenty of energy and a powerful prey drive that can cause aggression” rel=”noreferrer noopener”>. The majority of Boxer attacks involve children, as they do not know how to behave when they encounter Boxers. Children must be aware of how to behave around active and strong dogs, such as the Boxer. If the breed does not properly handle them, it can quickly become dangerous or even tragic. Owners will claim that their dog is affectionate, happy, cheerful, loyal, and fun. Although this is true for the majority of Boxers nevertheless, it doesn’t necessarily apply to dogs that have bad owners.

Untrained or poorly bred Boxers can cause enormous harm to humans, particularly to children. In addition, these dogs were initially bred in Germany in order to pursue and engage in dogfights. 

 It is impossible to predict when their natural instincts will start to take over.

      3. Labrador Retriever

Highlights: Friendly, Energetic, People-loving

It’s true that the Labrador Retriever isn’t as dangerous as some make them appear to be. Although the amount of Labrador bite deaths are very excessive, it’s worth pointing out that there’s an abundance of Labradors. They’re actually the most sought-after breed of dog breed within the United States (and for several years!).

Of course. For instance, Los Angeles is a city in the states with more criminal cases than the suburban area of Pasadena, CA. If you compare a city with 4 million inhabitants to a suburban area with 150,000 residents, the larger city will have more cases, despite being thought of as “safer.”

The issue with attack statistics for these breeds of dogs is that they do not take into account the number of people who own the breed. However, it is estimated that there could be hundreds of thousands of Labradors across America at any given moment.

To find them in this list of the most dangerous dogs will shock a lot of people. It’s like they’re the stereotype of the “family dog.” if you consider the number of them that exist, securing at number 7 appears to be quite low, isn’t it?

   4. Siberian Husky

Highlights: Playful, Active, Loyal

If you’re not under an abyss, you may have seen hilarious memes featuring a husky that is evil circulating on the internet. They may appear “evil” with their sinister-looking eyes and the black fur around them. But are they really so dangerous and aggressive?

Huskies are generally affectionate and social animals. They simply love people. The majority of owners will say they believe that their Huskies are smart and alert towards humans and other dogs. The problem can be that Huskies are constantly energetic and active, resulting in aggressive behavior.

When I look at isolated incidents, I’m able to tell that the majority of the fatal assaults by Huskies included children of an earlier age. It’s generally not good to allow large dogs to play with small children, particularly when the dog is extremely lively. Also, if the dog is not familiar with children, it could be disastrous.

Whatever the victim’s size and their age, Siberian Huskies are indeed dangerous breeds, as per the statistic of fatalities due to bites in America. If properly socialized and trained, they are delightful and fun dogs in any household.

   5. English Mastiff

Highlights: Good-natured, Brave, Dignified

An English Mastiff is, by nature, calm and gentle in most cases. However, just like any big dog and other big dogs, the Mastiff may become aggressive due to various reasons. For instance, unfair treatment or inadequate training could result in the situation.

Mastiffs must receive socialization instruction early in their lives. This is the only way to learn to discern the typical behavior of “the good guys.”

The breed of dog can already be shy around unfamiliar people. Without the socialization process, they’ll be untrustworthy of anyone outside the family. Additionally, the protective instincts of the Mastiff are activated, and they could be too protective, which can lead to unsafe situations.

This typical behavior of the Mastiff can result in unusual shyness and aggression towards people. Both can be dangerous for a dog breed this size. They measure about 36 inches and weigh as much as 300 pounds. That’s right! They are capable of doing quite a bit of destruction.

If they are looking to fight them, they’ll be able to do it easily. If you’re an owner seeking to adopt a Mastiff, then you’ll be taking on lots of responsibility in training the dog’s strong will.

  6. Bulldog

Highlights: Friendly, Brave, Calm

The Bulldog has faced plenty of controversy and criticism throughout the time. For instance, they’ve even been (unfairly) described as the dumbest dog breed worldwide. In the end, many people wonder if their lack of intelligence has something to have to do with their aggression?

Personally, I think they’re not understood. Owners view their inability to obey directives as a lack of knowledge. However, in reality, they’re slightly stubborn.

In reality, the responsibility lies with the owner. A Bulldog will not follow your orders or instructions if you’re not a steady and reliable leader of the group (or the family).

The dog’s nature and challenge to train and manage is a problem. Let’s look at this. It could be that the reason Bulldogs sometimes attack people could be because their owners didn’t effectively train their dogs.

Bulldogs are typically called friendly, gentle, social, and affectionate dogs. However, there is a lot of work and care for these breeds. If they’re properly socialized and trained, there shouldn’t be any reason for them to harm an individual with no reason.

  7. German Shepherd

Highlights: Intelligent, Devoted, Obedient

German Shepherds have been the most popular breed of any K-9 unit that is reputable. They’re often regarded as being synonymous with Police dogs. However, because they’re so reliable in fighting crime if put in danger, the dogs are able to cause danger to the people in their vicinity.

A typical, family-owned German Shepherd is convinced that it has only one purpose and job to safeguard the family. With this kind of attitude and devotion, accidents could occur.

If your German Shepherd sees someone as a danger to the family (your family), they will fight and protect. It isn’t easy to resist an attack from a German Shepherd attack.

They stand high at about 25 feet and weigh around 80 pounds of pure muscles, and an assault can be devastating and, sometimes, even deadly. Even if they do not intend to, they could accidentally injure children.

A German Shepherd is by far the most well-known family-owned dog guardian in the United States. Actually, in second place in popularity to Labrador Retriever, they’re the most well-known dog breed in America for a long time.

With the force of nature’s protection instincts and the ferocity and frequency of dogs like the German Shepherd, are you truly surprised that they’re as high on the risky breed list? We didn’t believe so, and neither did you.

    8. Rottweiler

Highlights: Loyal, Protective, Affectionate

The Rottweiler (also known as “Rottie” isn’t just one of the dogs with the highest price but is also among the breeds with the highest risk. Owning the Rottweiler will require you to pay for a premium. In exchange, you’ll receive one of the most fierce guard dogs that the world offers.

It’s not a secret that Rottweilers are slowly gaining popularity, moving from the 10th spot to the 8th most sought-after breed of dog within a couple of years. With the increase in the popularity of this fierce guard dog comes an increase in the number of possible dog attacks.

While the Rottweiler is generally a calm dog, they’ll go to any lengths to safeguard their group. Many owners describe them as fearless, loyal, confident, and courageous. These are wonderful traits in the temperament of the ideal family dog.

The Rottweiler dog is one of the quietest, most peaceful pet breeds in all honesty and fairness. I’ve had the pleasure of meeting many Rotties throughout my time, and they aren’t as vicious as they seem to be. I suspect that some external factors or reasons could allow a dog with such a soft disposition to make it to the top of this list.

Perhaps all the deaths were due to burglars who tried to enter the home. In that scenario, they were simply carrying out the “job.” Whatever the reasons, the statistics do not lie. Rottweilers are among the most dangerous breeds of dogs.

     9. Pit Bull Terrier

Highlights: Playful, Protective, Confident

Adults have advised me about Pit Bulls as a kid. For instance, I’ve been told that when the jaws of a Pit Bull bite down, their jaws could lock up by brutal force. The term used for this was ” lockjaw.” There’s an undisputed stigma associated with Pit Bulls in all of these stories of horror.

However, I’ve discovered that everything was exaggerated to a certain degree. The truth is that the media and the public tend to emphasize generalizing the Pitbull breed based on bad people’s behavior. There are plenty of great Pitbulls that won’t be featured in the news.

There are no inherent “bad dogs.” But some bad people might treat dogs in such a way that causes them to become aggressive, leading to them becoming “dangerous.”

If we look at statistics straight, Pit Bulls are considered to be the most dangerous breed of dog. Although they have been deemed the “most dangerous dog,” the Pit Bull can actually be an adorable dog.

They’re friendly, loyal, and truly enjoy being around people. If properly trained and socialized, a Pit Bull can be one of the most loving companion dogs. However, many Pitbull-related incidents are believed to stem due to dogs who have unreliable dog owners.

It’s not simple to raise the right Pitbull. Some people are abusive toward the Pit Bulls or even instruct them to be aggressive and violent. Due to their long-standing tradition as bull-baiting animals, the dogs require additional socialization and taking classes to help keep their habits in control.

Other Dangerous Dogs (Honorable Mentions)

These are the aggressive and dangerous dog breeds that did not appear on the mainline edition of the list. This could be because there’s not enough information within the U.S., or they were listed as unknown breeds in the reports. This means that they are “honorable mentions.”

   1. Chow Chow

Highlights: Dignified, Proud, Serious

It is believed that the Chow Chow is a Chinese dog breed popular for its blue-black tongues and lion-like hair. As with the other breeds on the list, they have been involved in numerous reports of attacks.

Indeed aggression is typical of Chow Chows. They usually exhibit an instinctual fear of dogs of the same gender. Additionally, smaller cats and dogs may draw out their inherent hunting instincts.

The best method to avoid any mishaps or accidents with your Chow is to begin an infant’s early and constant socialization. Always invite friends over and let your dog play with them as often as possible.

Even so, young children must be averted from interactions in Chow Chows. Chow Chows are extremely irritable, and being teased by young children may not end in a good way.

This breed of dog is trustworthy, independent, and solitary. But, they’re also naturally protective and can even be possessive. If this type of behavior is left unchecked, aggression in adulthood is very likely.

   2. Tosa Inu

Highlights: Brave, Confident, Dominant

Tosa Inu is the prized fighting dog breed that originated in Japan. The breed was developed to fight and defend and defend themselves, but not much else.

The Tosa Inu is not a popular dog breed. Even in their home country (Japan), Tosa Inus aren’t easy to find. Why would these fierce creatures not be on the list of the riskiest dog breeds?

It’s therefore not shocking that they’re not included in this list, which is determined by the number of dog bites. There are not many of them. However, they are popular. Akita Inu is a far more well-known breed than the Tosa. A larger number of dogs mean a greater likelihood of being attacked.

However, don’t be fooled; the Tosa Inu is indeed a dangerous dog. In fact, they’re so dangerous several countries have banned the breed.

Additionally, some states require pet owners to obtain permission to keep the Tosa. Certain prefectures of Japan have banned the breeding of Tosa dogs. This is one of the main reasons why there is a shortage.

If you are planning to keep a Tosa dog, be cautious. They are only suitable for those with the most experienced trainers and dog owners. There’s not much more terrifying than the 150-pound “Japanese Mastiff” charging at you.

   3. Bully Kutta

Highlights: Alert, Active, Responsive

The name Bully Kutta, ” Beast of the East,” is the best way to describe it. The breed was originally developed to hunt great guardians. However, their huge size and aggressive nature caused them to become popular as fighter breeds in India as well as Pakistan.

They measure thirty to forty inches in height and weigh as much as 170 pounds. Unfortunately, they continue to take part in illegal dog fights throughout India in the present.

One of the best ways to control the behavior of a Bully Kutta must be to allow them to interact with humans and dogs at a very early age. Regular socialization and instruction with a firm touch are necessary for this breed. Even socializing with other dogs could be dangerous at any age.

They might appear to be innocent at first or playful, but “play fights” with other dogs quickly become something that is fatal. They may tear apart the other dogs or even die trying. If the other dogs are submissive to them, they’ll remain in peace. But other fighting dog breeds aren’t submissive, either.

You can be sure that you must be careful with a bully Kutta. Children are a clear “no,” and it’s probably more beneficial for all dogs to be away from them as well.

  4. Alaskan Malamute

Highlights: Diligent, Playful, Loving

The Alaskan Malamute is like a more massive, bulkier model of Siberian or Alaskan Husky. They’re not generally dangerous breeds. The majority of owners will say they’re great with people, especially with children.

But the primary issue lies in the fact that the Malamute, as with the Husky, is full of energy that must be channeled to productivity. Inability to do this could lead to aggressive behavior.

What triggers the Malamute to display aggression is most likely their neglectful owners. Malamute requires mental and physical stimulation to ensure good health – the body and the mind.

The inability to let out the excess energy typically leads to destructive behavior, such as attacks on strangers. They can weigh as much as 100 pounds, and so if you encounter the aggressive behavior of an Alaskan Malamute, it could be risky.

Dangerous Dogs Act of 1991

In the 90s, The United Kingdom saw a rising number of attacks by dogs. A few of them resulted in serious injuries and deaths. As a result, the Parliament took the decision to intervene and pass the Dangerous Dogs Act to prevent these attacks.

The rules applied were to a small number of dangerous dog breeds. The Parliament also imposed strict prohibitions on certain breeds of dog that made it illegal for them to possess those “specially controlled breeds” in the United Kingdom.

Dog Breeds are covered under U.K.’s Dangerous Dog Act:

  • Tosa Inu
  • Pit Bull Terrier
  • Fila Brasileiro
  • Dogo Argentino

These are not just the specific purebreds included in the Act, but any dog that is crossbred with any of the four breeds listed. The Dangerous Dog Act has stirred lots of debate and was extensively criticized as discriminating toward dogs based only on the “breed label.”

A dog that appears to be an amalgam or has the characteristics of the four breeds is deemed “dangerous.” And unfortunately, it is the case that the United Kingdom court system determines whether a dog fits within the Dangerous Dogs Act.

Dangerous Dog Breed Legislation

The United States followed in the same footsteps as the United Kingdom, enacting breed-specific laws. The laws are distinct in every state’s jurisdiction.

It ranges from complete bans to restrictions on the ownership of aggressive or dangerous dogs. However, certain state governments have imposed restrictions on this breed-specific law.

Dogs that are affected by the law:

  • Mix breeds of the following types:
  • Pitbull
  • Bulldog
  • Mastiff
  • Staffordshire
  • Dogo Argentino
  • Canary dog
  • Wolf-hybrid
  • Rottweiler
  • and many more…

For more details on the rules for harmful breeds in your state, visit this page. The only states affected by this legislation are Arkansas, Colorado, Florida, Iowa, Kansas, Kentucky, Maryland, Michigan, Missouri, Ohio, Rhode Island, Tennessee, Washington, West Virginia, and Wisconsin.

Final Thoughts

So, do I believe that dogs are dangerous inherently? Yes, and no. On the other hand, some dog breeds are more aggressive than others due to their natural behavior or what they were bred to be in the past.

For instance, a dog breed specifically designed to fight and protect (look up: Tosa Inu) is bound to show aggressive traits over your typical dog. Naturally, aggression is a risk in situations.

But, at all times, whether a pet becomes involved in a dangerous situation is entirely in the hands of the dog’s owner. I believe that most of the fatal accidents involving those dogs in the USA originate from negligent owners. Or, it could be due to poor socialization or a lack of responsibility.

A large, agitated dog wandering around the neighborhood could be a sign of trouble. For instance, if the owners cannot take their big active dog on walks, it could cause them to become agitated. The energy they’ve accumulated could result in them digging an area in the backyard, thereby being able to escape.

They generally do well with people, whatever breed they are. All owners must take care of their pets and ensure that they receive the appropriate training in socializing. With a bit more attention and work, we might be able to reduce the deadly dog attacks across the globe.
