15 Most Dangerous Dog Breeds

Guardians or Threats? Let’s Explore the Most Dangerous Dog Breeds and How They Can Be Loving Pets

The moment I became a dog parent, completely changed my life. I never believed that there was such a special bond between a person and their pet. But yes, before adopting I made sure that the breed I was going to own would not be a dangerous one. I also raised my grandkids. So, it was essential for me to keep things safe around the house.

I feel like we don’t need words to understand each other, we offer unconditional love, and most importantly, we support each other no matter what. My sweet dogs are always there for me, especially when I need a good cry or feel overwhelmed by all kinds of emotions. They know how to make me feel better, without doing anything uncommon. I think that only pet owners can truly understand me. It’s an energetic connection that could never be broken.

My dogs play a huge role in my life, but I always make sure to also do my best for them. I am always there when they need me, and I do my best to ensure they get the best training. I can proudly say that the training they took at a young age, paid off later. I never had problems with them, and believe it or not, they never destroyed anything in my house.

It’s important to mention that my passion for dogs is so strong that I sometimes spend my time researching different breeds, trying to understand their needs and characteristics. It helps me escape from my overwhelming routines, while also offering me the chance to better understand my babies.

Genetics plays a huge role

Like many dog lovers, I used to be sure that every dog was simply a product of the environment they were raised in. I believe that if you show them love, and train them properly, they will become the perfect companion. Well, as I dove deeper into learning about different breeds, I realized that history and genetics also play a huge role.

I started paying closer attention to how different breeds behaved. For example, my Labrador Retriever is incredibly gentle and has a totally different temperament than my friends’ high-energy Belgian Malinois. Some breeds are naturally more protective, while others are so-called ”dangerous”. There are breeds that for some reason or another, have gained a reputation for aggression and bite force.

I looked at some statistics and understood that certain dog breeds do have some physical advantages, such as stronger bites, higher pain tolerance, and more protective instincts.

But before judging these breeds and their behavior, please remember that misinformation plays a huge role in the story. Breeds that were categorized as dangerous had irresponsible owners. I kept asking myself: What if they were raised differently? Wouldn’t that make an important difference?

The importance of a responsible owner

Basically, all these thoughts and questions without answers led me to write this article. I wanted to explore the facts and see exactly what makes some breeds more dangerous than others. I will also highlight how proper training and responsible ownership can make all the difference. So, the last part of this article will be dedicated to ways to prevent aggression. I truly believe that it could be extremely useful for most of my readers. Read on and see if these breeds are real threats or just… misunderstood.

Oh, and it doesn’t matter if you are already a dog owner or preparing to adopt your first furry friend! The article will give you important insights you need to make informed decisions.

Which breed has the strongest bite force?

Even though every dog can become aggressive sometimes, certain breeds are statistically more likely to provoke serious attacks. Unfortunately, these kinds of incidents happen when the dogs are not trained.

Did you know that a Turkish breed, called Kangal officially holds the strongest bite force? Kangal is a mighty guardian dog, developed to protect livestock from predators. His bite force is around 743 PSI.

Kangal is not the only breed associated with an incredible bite force, and let’s say that the second place on this top is held by the American Pit Bull Terrier, whose bite force is approximately 235 PSI, meaning that it’s significantly lower.

You’ll discover more information about 15 breeds known to be extremely dangerous. We’ll discuss essential insights, important characteristics, and risks. Are you ready? Keep reading.

15 Aggressive Dog Breeds

1. Pit Bull Terrier

This breed comes from England. In the 19th century, Pit Bulls were designed for strength and high pain tolerance. Once they were brought to America, they became popular farm dogs, known for their loyalty.

Pit Bulls are considered extremely dangerous due to their bite. They lead most of the fatality statistics, especially because of their force and tendency to hold and shake when attacking. Their muscular build, power, and most importantly, their history, contribute to their reputation.

Times have changed. Despite their reputation, there are a lot of well-raised Pit Bulls that are extremely loyal and affectionate. However, irresponsible ownership or lack of training can easily lead to aggressive behavior.

For example, there were reported 284 deaths from Pit Bull attacks. So, I am not joking when I say that even though these dogs seem kind and sweet, you’ll still need to be extra cautious around them.

It’s interesting how one of the most feared breeds, is also one of the breeds that love children the most. They can be excellent family pets and have a strong desire to always please their owners.

So, let’s say that Pit Bull owners need to pay attention to the way they raise their dogs and establish clear boundaries. Providing them with a safe and positive environment encourages good behavior.

2. Rottweiler

Rottweilers are responsible for 45 fatal attacks. Sounds scary, but not all Rottweilers are that aggressive. Originally, Rottweilers were used to guard livestock and pull carts for butchers in Germany. The breed is known for its strength and protective nature.

Rottweilers have a surprising bite force, and their natural guarding instincts are what make them seem scary to a lot of people. The problem with these dogs is that they become extremely protective when someone is approaching their owners, leading to aggressive behavior.

However, with a lot of patience and a good training program, I truly believe that any Rottweiler can become calm and form strong bonds with their family. Once they trust the environment they live in and learn how to control their instincts, they become extremely affectionate and loving.

Just keep in mind that inexperienced owners might end up with an uncontrollable dog. So, if you are planning to adopt a Rottweiler, make sure that you stay informed and follow a serious training program.

If you already have a dog of this breed, feel free to share with us any useful tips and tricks you learned throughout the journey.

3. Boxer

Boxers have a history of non-fatal bites but are known for some violent attacks. They are muscular, energetic, and very protective. The breed originally came from Germany, and the Boxers were hunting dogs. Later, they became popular guard dogs.

These dogs have high energy levels and protective instincts. So, as the other breeds I mentioned until now, if not properly trained can become overly excitable and even aggressive.

If you are a first-time dog owner, stay away from this breed. Boxers can be very stubborn and their strong-willed nature could make you feel overwhelmed, especially if you have zero experience.

Despite their intimidating appearance, Boxers are known for their playful and affectionate personalities. They are great family dogs when raised correctly but need firm training to prevent hyperactivity from turning into aggression.

A structured environment helps prevent behavioral issues. Oh, and you should also know that Boxers need plenty of exercise and mental engagement. So, if you want to adopt one, prepare yourself: mentally and physically.

4. Doberman

Dobermans are known for attacking people and other animals and are highly successful guard dogs. The Doberman is an iconic dog due to its unique look. Their stiff posture makes them seem like they are always on alert.

Dobermans are naturally protective and can be aggressive if they sense a threat. Their speed and precision make them formidable if not trained properly.

A well-trained Doberman is extremely loyal and loves to have a clear role in the household.

Keep in mind that socialization, clear leadership, and obedience training are necessary to prevent overprotectiveness.

5. Bullmastiff

This breed comes from England and was created by crossing Mastiffs and Bulldogs for strength, size, and most importantly, protection instincts. Once they become aggressive, they also become extremely difficult to control, so strong leadership is needed.

Bullmastiffs are calm and gentle with their families but require early training and socialization to ensure they do not become overly protective. Keep in mind that positive reinforcement, early exposure to different environments, and firm leadership can shep really well even the most stubborn Bullmastiff.

People usually love this breed because the Bullmastiffs are alert, fearful, and great for home protection.

Even though it’s considered a dangerous breed, attacks by bullmastiffs aren’t as frequent as you may think.

6. Siberian Husky

Huskies are known for being extremely beautiful and looking like wolves, am I right? The breed comes from Siberia and these dogs’ ability to work tirelessly in extreme climates made them important companions for nomadic tribes.

Huskies are also famous nowadays and have high energy levels, an independent nature, and a strong prey drive. Even though they are not naturally aggressive to humans, their stubbornness and intelligence can lead to behavioral problems, especially if they are not properly trained.

If you are thinking about adopting a husky, here is one thing you should know: if they get bored they will destroy your house.

7. Alaskan Malamute

Alaskan Malamute was developed by the native Inuit tribes for heavy-duty sled pulling. So, compared to the Siberian Huskies which were bred for speed, Malamutes were bred for endurance and strength.

This breed is particularly interesting and hard to deal with, because Alaskan Malamutes may try to establish themselves as the pack leaders. They require an experienced owner.

Despite their aggressive nature, Malamutes can be affectionate, playful, and great companions.

8. German Shepherd

German Shepherds were developed in the late 19th century in Germany. Shepherds were hard-working dogs at that time. Their intelligence and adaptability transformed them into the most wanted breed for the military and police.

They have an extremely protective nature, and all they want is to protect their families. So, trust me when I say that an experienced owner is totally needed when it comes to this breed. Without training, their high drive can rapidly turn into territorial aggression.

But here is the good news: German Shepherds are among the most trainable breeds in the world. They are even known for being incredible therapy animals.

I love how their power can be easily transformed into something else or simply adapted to the environment they live in. If, historically, they were known for their working power and aggressiveness, it doesn’t mean that things are the same today.

9. Chow Chow

Is there someone here who doesn’t love Chow Chow? I don’t think so. This is one of the oldest dog breeds, originating in China over 2,000 years ago. At that time, they were bred as guard dogs and even war dogs.

Chow Chows are territorial, and… let’s face it: they hate strangers! Their stubborn personality can make them difficult to train, and if they are not properly cared for, they may become aggressive toward unfamiliar people and animals.

Despite their aggressiveness, once they feel safe they are extremely loyal to their families and can be affectionate. However, keep in mind that they are not as openly friendly as other breeds.

10. Cane Corso

Did you know that the Cane Corso breed descends from Roman war dogs? They were used for guarding, hunting, and even military purposes. They are incredibly strong, intelligent, and a perfect breed when you need protection.

Despite their image of being one of the most dangerous dog breeds, Cane Corsos are deeply loyal and bond strongly with their families. But don’t get me wrong! They still need strong leadership and should not be owned by inexperienced dog handlers.

Have you ever met a Cane Corso in real life? How did the meeting go?

11. Great Dane

Originally bred in Germany for hunting wild boars, Great Danes were later transformed into great companion dogs. When I first saw a Great Dane I was impressed by his size, which made me see him as a potentially dangerous creature. Once I got closer and we basically became friends, things completely changed.

Great Danes are affectionate and love human companionship. However, proper training is required to manage their size.

Correct training from an early age is crucial to prevent them from becoming unmanageable due to their size. They also need positive reinforcement and consistent guidance.

12. Dogo Argentino

This breed was developed in Argentina and has a high pain tolerance. This breed was often used for hunting wild boars and pumas. Dogos have a fascinating dominant nature, and if they are not properly trained can become territorial and aggressive towards strangers and other animals.

Dogo Argentinos are highly loyal and would do anything for their owners. So, if you are considering adopting a Dogo make sure you start early training and establish firm leadership to prevent any dominance issues.

13. Akita Inu

The Akita, originally from Japan is a very big dog. He has a strong instinct to protect his family and has problems socializing with other dogs. Akitas are known for being stubborn.

In the United States, Akita is a popular dog, even though it is considered one of the most dangerous breeds and is the 3rd breed most likely to bite unprovoked.

14. Wolf Hybrid

This one is a mix between a domestic dog and a wolf. The problem with this breed is that it retained many wild traits, becoming extremely unpredictable. Their instincts make them prone to territorial aggression and high prey drive.

It’s interesting how Wolf Hybrids are not domesticated in the same way as regular dogs. They require specialized care and should not be kept as typical pets. Only experienced handlers with knowledge of wolf behavior should own them.

15. Perro de Presa Canario

This is probably the most dangerous dog breed ever, I recently discovered that it has serious bans and restrictions in Australia, Singapore, New Zealand, Ukraine, and Romania.

Presa Canario is known for being extremely aggressive and very hard to train. The breed is also fighting other dogs and hates to be trained.

Some people believe that with the right techniques and training practices. a Presa Canario dog can be a loyal pet for a family. However, I suggest you stay away from all the breeds that seem too much for you and could put your life in danger.

There are multiple dog breeds available, and even more sweet dogs can be found in shelters and are ready to be adopted. You don’t have to take any risk. Just choose a breed that suits your lifestyle.
