What Are the Most Dangerous Dogs?

Dogs are some of the most adorable pets a person can have. There are very few other pets that can even come close to a dog. Not even a cat can beat a dog in being a man's best friend. Having said that, there are certain breeds of dogs that can be quite ferocious and can make you wet your pants if you treat them wrong. Here is a list of the world's 8 most ferocious dog breeds.

These can be quite gentle companions if you bring them up the right way, but beware—do not mess with them or you may end up in a hospital! This article covers the following 8 ferocious and dangerous dogs.

  1. Pit Bulls
  2. Rottweilers
  3. Doberman Pinschers
  4. German Shepherds
  5. Boerboels
  6. Boxers
  7. Presa Canarios
  8. Alaskan Malamutes

1. Pit Bulls

If someone begins talking about ferocious dogs, pit bulls are one of the top breeds that come to mind. Of course, much hype has been created by the media and Hollywood about their ferociousness. The pit bull has its origin in the United States and weighs between 30–55 lbs. This breed is the result of interbreeding between a breed of bulldogs and terriers.

The result is a pit bull terrier that has the athleticism and strength of the bulldog and gameness of a terrier. Though the locking of their jaws has been proven a myth, it still has one of the most ferocious bites. Historically, these dogs were bred for dogfighting. Though these dogs are bred as normal pets nowadays, they are still a breed you need to watch out for.

The pit bull terrier's genetic history is thought to genetically predispose the dog to higher levels of aggression. As an owner, however, you have the power to reduce the likelihood of having an aggressive adult pit bull through thoughtful rearing. According to, the two most important things you can do for young pit bulls is "provide [them] with frequent socialization opportunities with well-behaved, well-socialized, friendly dogs" and "protect [them] in the event that another dog tries to attack [them]."


2. Rottweilers

This breed of dog comes from Germany and weighs between 85–110 lbs. They have strong and powerful jaws. The breed is bred primarily for guarding purposes, and you can expect a guard dog to be more aggressive than a normal dog. Though these dogs are good-natured and obedient, they usually hate strangers and other dogs as they are highly territorial. This natural tendency makes them quite aggressive and ferocious.

As the owner of a young Rottweiler, you have the ability to help curb your dog's aggression. Two important things steps you can take are to sign them up for obedience class and use positive reinforcement training. For a variety of methods to properly train your Rot pup, check out this article by Wag!


3. Doberman Pinschers

This is one tough, loyal, and aggressive breed of dog. (In fact, they might be one of the most loyal breeds around!) These dogs can be gentle and wonderful family pets if they are trained properly. However, if you provoke them, they can be quite aggressive and dangerous.

These intelligent and alert dogs serve well as guard dogs. No person can trespass on a property guarded by a Doberman Pinscher due to its tough and aggressive nature. These dogs can attack without a second thought if they perceive any danger to their owner or property. This is what makes them some of the world's most ferocious dogs.

Training a Doberman Pinscher correctly isn't as difficult as one might think. There are three primary steps to follow in proper Doberman training. Of course, early socialization, bite management, and impulse control are all huge parts of rearing a Doberman from puppyhood, so be sure to do you research and talk with qualified professionals.


4. German Shepherds

As the name suggests, this breed comes from Germany. The German Shephard weighs between 70–100 lbs. They were originally bred as guard dogs for sheep against the attacks of wild animals such as wolves. Now, these are bred both by homeowners as well as the police.

Their reliable and obedient temper, as well as their intelligent, agile, and fearless nature, make them excellent canine units. These are probably the most popular dog among law enforcement authorities. They can be reliably deployed in airports for tasks such as sniffing out bombs, drugs, and illegal paraphernalia. They are highly active dogs and need constant physical activity.


5. Boerboels

Boerboels come from South Africa where they are bred for guarding the homestead. The word boerboel translates into “farmer's dog” in Afrikaans. The general belief is that these dogs came from the interbreeding of certain African breeds and the breeds brought by the Dutch, British, and French settlers.

They were also used as the first line of defense against predators. These dogs are known to be calm and stable, at the same time being agile, strong, and courageous. They are also known to have strong territorial instincts, which makes them a popular choice among farmers as guard dogs.


6. Boxer

The Boxer originated in Germany. These dogs are very strong and agile and can weigh between 50–70 lbs. Their energetic and playful behavior gives them a label of being headstrong and difficult to train. Though they are highly energetic, they are not aggressive or violent by nature. They can also appear aloof and unfriendly to strangers.

However, do not make the mistake of messing around with them, as it may land you in serious trouble. The dog may attack you anytime and anywhere, but only in certain circumstances. These dogs are often dangerous due to a lack of socializing. One must be extremely thoughtful and attentive when raising and training a Boxer.


7. Presa Canario

These dogs come from the Canary Islands. They are known to be dominant and have strong character. These were known to be bred as hunting and killing machines and were normally used in fighting rings. They can bring certain death to their prey if they attack. They require regular training and early socializing to keep them obedient.

They can be aggressive towards strangers and other dogs in some situations. If properly trained, they can be very gentle and noble to their families and can be great guard dogs.


8. Alaskan Malamute

This breed is known to be fierce due to its strong facade and energetic body. They are usually quiet and loyal, at the same time being independent, which makes them quite hard to train. They are known to have great survival instincts. They are feared due to their capabilities and versatility of doing things beyond that of a typical dog, such as pulling a sled, herding reindeer, and serving as a watchdog. They tend to become aggressive if they are bored. Hence, they need proper care, exercise, and control to avoid aggression.

So, these are some of the world's most ferocious dogs you can find. If properly trained and bred, they can be the best friends you can get, and if crossed, they can be quite dangerous, and you may pay dearly.

Questions & Answers

Question: Do you think all of the eight most ferocious dog breeds are dangerous?

Answer: The answer to that is very simple: Any plant, human or animal grows according to its environment. Having said that, a lion will eat meat and not grass. A cow will eat grass and not meat. Every animal has a natural instinct; you cannot beat that. You may love your Doberman, but if someone other than you enters its territory, it can become ferocious.

Question: Why do you think a pit bull is ferocious? A chihuahua, for example, is much more aggressive.

Answer: There are barking dogs and there are dogs that can send you to a hospital for a long time. That is the difference between a chihuahua and a pit bull.

Question: I live on the main floor of a house, and my place faces the backyard. My landlord lives above me and is getting a Rottweiler puppy for their three young sons. I'm afraid it will attack me or my cat. Is this likely?

Answer: Not necessarily. It really depends on how your landlord will train the puppy. If he trains it to be a well-behaved dog, then it shouldn't be of concern. Also, keep in mind that dogs instinctually (with some exceptions) bark at cats. So, I don't think you should be concerned.

Question: What about pit bulls? They aren’t aggressive but only if they are bred that way?

Answer: True. And that means that they can get aggressive, right?

Question: Do you recognize that writing biased, one sided opinion papers on the internet breeds unnecessary fear?

Answer: I do not believe that the article is either biased or opinionated in any way. Just ask for a moment when someone asked you, which is the dog you fear the most and you gave out a name. Does it make it a biased opinion? Or is it just your viewpoint? What I have done here is publish my viewpoint. You are much welcome to agree or disagree with it. And most of the dog breeds I have mentioned here - I either had a personal experience with them or it is through my observation.

Question: If a dog bites you - what should you do to the dog?

Answer: Nothing much. You should ensure that the dog is properly vaccinated so that it doesn't spread rabies. And for yourself, take injections so that you are not a victim of rabies. The real question is what did the perpetrator do the dog that it decided to bite?

Question: Are pit bulls loyal to their owner?

Answer: I would say yes. I don't have first-hand experience (I haven't bred a pitbull). But, I have seen a few people breeding them and the latter are definitely loyal to them.

Question: I've been around Pitbulls all my life and never have been bitten or attacked by any of them. Most of them weren't mine, how do you explain this?

Answer: I am from India. Street dogs are a common sight for me. There are probably more street dogs than there are cars or bikes in a residential area. But I haven't been bitten by any of them. Does it mean that I should be bitten by any of them to realize that I should not mess with them?


josh on August 29, 2020:

i have a pitbull and a boxer they love eachother :)

Nathan on August 27, 2020:

Your disclaimer at the beginning isn't strong enough. You try to emphasize that this *can* be the case... but if you were to explicitly and maybe even repeatedly say, early on, that these breeds *may* have a tendency towards aggressive behavior if not socialized and neglected, but with attention and care, they can be loving and no more a threat than any other. Make it clearer and you would have fewer people feeling defensive in the comments: I imagine the people upset raised their dogs, more or less, properly. My Shepard/Pitt mix has never shown any sort of aggressive behavior, though he spent very little time alone and from a young age went everywhere with me: was exposed to lots of people and other animals and I made sure he knew when he was doing something he shouldn't be. The only two dogs I have personally known that bit someone was a pomeranian and a dachshund, both had owners that never tried to correct them and let them walk all over like they owned the place. I have known well-adjusted examples of both as well. Just a suggestion.

Gracie on August 25, 2020:

I am scared of the pit bull

Bea Fitz on August 14, 2020:

This is a very ignorant list. We have both a German Shepherd and a Malamute. They both love kids, other dogs, cats. When my daughter was two we didn’t hesitate when we left her alone with our dogs because we knew they wouldn’t do anything to her, and they never did or do. Plus, I grew up with a Rottweiler and not one, not two, but THREE boxers and they literally let me dress them up in sunglasses and ballgowns. When I was in collage my mom bought me a Presa Canario puppy who I had for 9 years and she was the sweetest soul, god bless my my Kali. It’s not the dogs fault, it’s the owners. Why don’t you include any other breeds on here? Chihuahua? Dachshund? Bichon?

Ria on August 10, 2020:

Can you now do an article about the most dangerous dog owners? I feel like that would be more relevant than focusing on the breeds (YAWN)

Donna Holmes Parks on July 21, 2020:

Just wondering what in the world qualifies you to write about dog behavior? No references, no statistics, and, frankly, not great writing.

Byron on July 21, 2020:

is'nt a chihuahua the toy breedof a pit bull

Bleu on July 15, 2020:

My Doberman is my service dog and he is great with everyone. Strangers, kids, animals. Doesn't matter who you are he is ok with you. He will even let the lawn guy come in the gate while he is hanging out in the backyard. My last service dog was a Staffordshire terrier (most call him a 'pit bull dog'). He was the sweetest thing and the biggest push over who also was acceptable to strangers and anyone else. Never once with either dog have I had issues of aggression. Im sure they would protect me if needed but they are not a dog constantly standing on the thin line of attacking an unknown person or not.

To flat out just say they are aggressive is just wrong.

Ishmael Sibisi on July 06, 2020:

This is biast and dangerous because it helps perpetuate the stereotypes that lead to some breeds being mistreated. Aggression is not genetic with a bad owner even a poodle can be a aggressive dog.

Karthik Kashyap (author) from India on July 04, 2020:

Sarah, Debbie: Thanks for commenting. Please enlighten me how the article is garbage. Else, your comments will be deleted.

Sarah on July 03, 2020:

Most ridiculous and biased article I have read yet. This is complete garbage.

Debbie on July 02, 2020:

Very ignorent article. People who don't know anything about dogs should not be writing about them

Jaclyn on July 01, 2020:

There is no such thing as a specific breed that is aggressive because you can always train the dog to be kind so it all depends on the owner and breeder

LONR on June 29, 2020:

First off, there's no bad dog and or pet, only bad owners. Any animal, especially dogs, are like kids, in a sense...they need TLC and attention at all times, just. like. kids. If you show them love, respect, obedience, they will be the most loyal, protective, caring, loving dogs (pets) ever. However, if you do not show them love, and only teach hate, aggressiveness, and breed them to be killing machines..then, whaddya expect? Seriously? No dog / pet is better or worse than the other. You get what you put in.

Kris on June 28, 2020:

Honestly I expected no less. I scrolled down seeing every controversial dog I expected to see (Except the Alaskan malamute, they're literally just aloof and stubborn) I've had so many positive interactions with pitbulls I swear they are the best family dogs you just need to treat them right. These dogs aren't considered dangerous because they do it by themselves. These animals are targeted by bad people because they look very intimidating, those bad people adopt them and turn them into monsters. That's why people are so scared of them, because some really bad people turn some sweet natured intimidating dog and abuse it until it ends up hating people

Emri Wheatley on June 23, 2020:

Ok first of all the German Shepherd is so sweet and the Alaskan Malumute is just hyper it just wanted to play

Karthik Kashyap (author) from India on June 23, 2020:

Jakcrowder, Nunya: Thank you for your comments. Clearly, you have commented without either reading the article or understanding it. I urge you to read it again.

Jakcrowder on June 23, 2020:

Why do all of you so called pages for animals write the most absurd things against them? Try learning and presenting the truth. Animals,any animals are like humans. Each different,each with own personalities.As a woman am I supposed to think every man I see is going to attack me? Of course not,so don’t perpetuate the same myths about dogs!

Nunya on June 22, 2020:

This is THE MOST retarded “article” I have ever seen I-

Chad Cook on June 18, 2020:

The comment on pitbulls is absolutely wrong 100% the dogs even when put in the pit had to be handled by owners and strangers if they were human aggressive they got put down. I have owned 3 pitbulls and my parents 2 they are the most loyal breed on the planet I would not own either other breed APBT #1

Karthik Kashyap (author) from India on June 17, 2020:

Err.. Michelle... What??!! You mean to say nationalities don't exist?

Sarah: Thank you for your comment. I urge you to re-read the introduction before commenting.

Michelle Dorminey on June 17, 2020:

This article is ridiculous, you should be embarrassed. This is as ridiculous as classifying any race or nationality in people as more dangerous. Dog prejudice.

Waldo on June 17, 2020:

Sounds like a 5th grader wrote this article

Sarah on June 17, 2020:

It is not the breed that is aggressive by nature it is the human being that raises it. Get your facts checked most of these breeds are the sweetest dogs you'll ever encounter.

Eddie on June 14, 2020:

This person is very uneducated. Don't know why they are giving opinions on what dogs to not mess with because there is bigger and more protective dogs. Like dogos and cane corso.

Karthik Kashyap (author) from India on June 11, 2020:

Pitbilladvocate: Your response is particularly interesting. If calling an aggressive breed as aggressive is 'racism', then it should apply to almost anything. Calling a snake dangerous or rabbit a docile animal can all be racist. Think about it.

Pitbilladvocate on June 10, 2020:

As an owner, trainer and advocate for pitbulls, this article just perpetuates the discrimination of an amazing and loveable breed which is also a form of racism

Rory on June 09, 2020:

This article is garbage. Little to no factual information, just breed rumors from the last 20 years.

Naj! on June 09, 2020:

Some of these breeds were not only used for dog fighting but specifically bred for it, such as pit bulls. It’s in their dna. The fact is that any pit bull can snap at any moment, including turning on their owners. It’s just easier for a pit to kill a kid than an adult and that’s why they are known as kid killers. The pit bull has all the attributes of a perfect dog fighting machine. It’s got heart, it’s game, and it has the power in its jaws and body to do more damage and quicker than most dog breeds. It also won’t stop on command unless it is unusually intelligent and well trained.

Hally on June 08, 2020:

There’s no such thing as Lock Jaw It’s absolutely false

Mc on May 26, 2020:

You are an ignorant person .... more dangerous writing things like that than the breeds you pretend to know about.

I hear Walmart is hiring....

Ja on May 21, 2020:

This guy is an idiot.

Toni on April 28, 2020:

I agree to disagree!

Stella on January 20, 2020:

This hole thing is wrong! Dogs are only mean and aggressive if you train them to be like that! Pit bulls!? I know A lot of ppl say pit bulls are “Mean and aggressive” but that’s only cause ppl train them to be like that! Same thing goes to all dogs! I have a dog that’s half German Shepard and he is soooo friendly! I love him and he loves me back! Don’t just say there mean And aggressive from what you saw at a park or something like that!

Amy on December 23, 2019:

This article a perfect example of fear mongering and careless research. For example:

1. You claim that these dogs can be gentle if you bring them up the right way, but if you mess with them they will suddenly become aggressive killers. Some dogs (DOGS, not BREEDS) are more powerful minded than others, in the same way that some humans are more active, or more adventurous than others. The breed may determine whether a dog is more/less trainable, stubborn, obedient, or protective, but it does not determine temperament. You will find an endless number of owners of the breeds you mentioned that will say they can do anything to their dog and their dog will be completely submissive.

2. A pitbull is not a breed of dog. It is a term to describe several breeds of dog.

3. You mention that a fierce dog isn't a bad dog. Well, actually, a fierce dog is a bad dog, if the owner doesn't intend to have a fierce dog. Again, training could help this situation, or getting a dog with the right temperament to match the owner's skill/activity level.

4. You say malamutes are feared for their versatility and ability to work? I have NEVER known of someone watching a sledding happily pulling a sled and think, "Dang, that's terrifying."

5. "A fierce dog doesn't necessarily a bad dog." This sentence is grammatically incorrect.

Ultimately, humans have a lot of control over whether their dog is a guard dog or a couch potato, regardless of the breed. A good owner will take the time to make sure they have a happy, balanced dog. Behind every dog attack there is an irresponsible owner, and a dog that suffers for it. Breed is irrelevant.

Maybe instead of writing articles based on your opinion and your friend's opinions, you do some real research and talk to actual dog experts.

ashayla on December 05, 2019:

I have a Doberman and he's nice

Cat on December 01, 2019:

I am offended to because I have a pit bull and she would not hurt anyone and I also had a boxer that boxer would not hurt anyone and are u trying to scare people and kids because what if there are kids on here I would not do this and STOP!

Rachel on November 07, 2019:

First personally I’m offended by this because I have 2 pit bulls blaze and snoop and they wouldn’t hurt a fly secondly now I’m sort of scared of my dogs

Unknowen on September 04, 2019:

THIS IS B.S. I HAVE A PIT BULL AND A DOBERMAN! They both are the the sweetest dogs ever

MizN on August 06, 2019:

Don't write articles about things that you have little to no actual knowledge about. All you are doing is perpetuating stereotypes that have put these animals in danger. And as far as "researching a subject," Anyone can read other people's work and rewrite it, then call it the truth. Become a vet. Get a license as a trainer. Work in an animal shelter. Then you can talk. You don't even list your sources. Your opinion and that of others is exactly that, opinion. And how trustworthy is your research resources? You could be quoting someone like you. I will not apologize for my passion. You should apologize for your ignorance.

Batman on July 31, 2019:

German Shepherds are NOT dangerous at all! My aunt has one and he is the sweetest and most playful dog ever! Chihuahuas also ARE NOT DANGEROUS!!!! I have one and she will not bite me no matter what I do but she’s bitten my cousin twice, but she’s just not used to her, she lays on of course she’s gonna bite her. My other cousin also has two chihuahuas and yes they bark and growl but that’s because they’re protective. My chihuahua doesn’t even try to kill my bunny,but she is protective, she barks at other dogs but she’s just protecting me. But almost all the time she’s either eating, or sleeping. So,don’t judge a book by its cover, a dog is usually only aggressive when protecting its owner or because it has been mistreated, so get to know a dog before you judge it.

Batman on July 31, 2019:

Pit Bulls are NOT dangerous! Pit Bulls are one of the sweetest dog breeds. I’ve met LOTS of Pit Bulls and they were all wonderful dogs.

Sav Santilli on July 27, 2019:

I live in a house connected to a dog rescue and am the full-time caretaker. I've had a few of each breed listed here and I have to say that this list is completely inaccurate. The sweetest breed I've had? Pit Bull. (I've had numerous of each of the breeds classified under Pit Bull.) The meanest breed I've encountered? Chihuahuas.The breed I wouldn't want to mess with? Human. (And Chihuhua. I have seven here now and they are the meanest dogs I have ever encountered in my four years living here.) This list is opinion, and it's the wrong opinion at that. I don't believe any research went into this whatsoever. Reading a few articles and watching news clips doesn't give any insight into what these breeds are really like. They are kind, loving, gentle, loyal and have more humanity in their toenails than most humans do in their entire bodies. I suggest going and doing actual research. Getting bit is a job hazard for me, but I have never been bitten by any breed listed here. I would recommend any of these breeds, especially Pit Bulls, to families with children. They are the Nanny Dog, after all. I would be interested in reading a follow-up article after you go and actually research these breeds. Get up close and personal with them. I guarantee you'll want one of your own.

Jessica Gallardo on July 16, 2019:

A boxer is a dangerous breed? You are absolutely out of your mind or have clearly never met a boxer before. Ridiculous.

Cary on July 16, 2019:

I have yet to meet an owner of any of the above dogs that would agree with you. My chihuahua may not put you in the hospital, but she is much more likely to bite you than my doberman pinscher ever was! We had two dobies who were the sweetest dogs ever. We also had dalmatians who because of their nervous nature were more likely to bite as well, if they were scared.

Jessica on July 07, 2019:

This is such a useless article. I have owned American staffies for years and they are the kindest most beautiful breeds possible. We have had a sob who had grown up with ours and he had been boisterous, and over loving with them as kids can be and they are the most tolerable and loving breed I have ever known. We are also Judy about to bring a Doberman into our family so your article is invalid..

Scarlett on June 29, 2019:

Pethelpfull...more like petuseless.

Firstly, I have had the privilege to have pitbulls and german sheppards. You do breed specific articles labelling dogs when you should be labelling their owners. A bad owner means a bad dog.

My german sheppards which I have had more than 3 quarters of my life are great companions amd pitbulls secondly are not agressive at all.

Take as a person, if you sit in fear and agressive behaviour all day from the day you are born, you become what surrounds you. Same goes for dogs.

Stop writing articles labelling dogs as agressive and start learning your dogs and what they need, not what you need..

Tracy on May 05, 2019:

People also tend to expect animals to lay there and do nothing while children pull their hair, try to ride them and do all kinds of things. A kid was standing outside of MY fence shooting my dog in the face with a water gun! Sometimes they attack because they are being hurt or taunted. We not only need to train the animals but also the humans!!!

naura on May 01, 2019:

My dog is not included here but super protective

Michael on April 28, 2019:

I own a Staffy and honestly with all of these needs except for the ones that seem to have their own agenda Doberman especially, if you can't outsmart the dog to train it, it will outsmart and overcome you.

Debbi on April 25, 2019:

I love reading comments to things like this. Now mind you I am in no way shape or form trying to belittle or attack anyone who has their OPINIONS. I have worked with all types of domestic animals. i am a Pit Bull rescuer. I have 3 sons that have been raised for the last 20 years with nothing but pit bulls. Now mind you a lot of people cant tell the difference between an American Pit bull terrier and a staffordshire terrier.The only reason people know what a bull terrier is well because he has the funny snout. Oh and he was the mascot for the Target. I have never been bit or even growled at by any Pit bull I have rescued nor any that I have worked with. Even the ones I had to restrain at work to get blood tests from. I've had friends and families that have owned them and never a problem. Just the other day my arm was grabbed by a Jack Russel Terrier because she was attempting to bit another dog and instead of me allowing that I put my arm in the way so she grabbed me instead of the other dog. I have Chihuahuas attempt to try to eat my face off and Dachshunds as well. I have always had a motto.. Anything with teeth is considered dangerous and can bite you. Really do your research better yet get to know some of these animals before you breed shame or become afraid. Just like people there are good and bad dogs. Don't judge a dog just like you wouldn't a person. Better yet a cat bite can actual kill you. I watched a fellow tech lose instant feeling in her arm because a cat bit her and she was rushed from our facility to the ER because of it. Again I have dealt with all breeds and types.. My sons have never been bitten nor attacked by any dogs including my neighbors Bull Terrier. I enjoy my job and I do have all rights in the world to defend my Bully companions because that's all they have ever been. BTW Pit Bulls aren't so bad. At one point in time they were considered Nanny Dogs.. So really don't blame the breeds they will do anything to make their owners happy. They are that loyal to whom ever they are by. Think about it. If you were starved for days and locked in the kennel and the only way you got eat was by doing what your owner trained you to do... Yall have a great night... #bullieshavearightnottobejudged #judgethedeedNotthebreed

Olivia on April 24, 2019:

This article is not true made up of true facts yes in the past these dogs have been trained to be more aggressive but aggressiveness is not a bread my neighbour have 3 pit bulls and one likes to visit my house quite a bit when she sees my cat she runs I have met a Chihuahua and the first thing it did was try and bite me.

Talulah on March 25, 2019:

Ive heard way too many pitbull horror stories, which make me believe that they are dangerous. Most recent about a little girl who almost had her arm ripped off. She was afraid of the dog. Why would he attack her? Otherwise docile with the owners and visiting another family? A calm 8 year old dog suddenly attacks a baby? I love dogs, but am now afraid of the breed. They can apparently turn on a dime with no provocation.

g-dog on March 20, 2019:

German shepherd all the way

Mike on March 14, 2019:

It seems no one understood what was being said. Or maybe I didn’t. The person that wrote the article was clear about what most of you are saying. “A dogs behavior is simply based on it upbringing”. But what the author is trying to say, (I think) and I would fully agree, is that if the dog was to be aggressive these would be the top 8 that would tear you up without breaking a sweat. Of course the Akita isn’t in there sand it should be. These are all fantastic breeds. I’ve had a few of them with no issues. But having experienced the power and potential of these dogs as I spoiled them, even I realize they can be lethal.

CD on March 07, 2019:

This is a great list. It is not all inclusive or exclusive. All dogs can be mean. These dogs can be vicious. I like that quality. I have had 4 Chow Chows. They were lovable and me. They were lethal to strangers. I also had a Jack Russell and a Yorkshire Terrier. They were lovable and me. They thought they were lethal. They were not!!! They did bite strangers but they couldn't protect me. They could "alert" me. Then I could protect them. This is not a "bad" list. Those dogs can be nice AND they're great for protection. All dogs must be "socialized" in order for them to be friendly. My dogs are not socialized. My yard is fenced. My doors are locked. My Yorkie will announce "your" presence. My Chow Chow will protect me.......AND I will protect her!!!!!!!!

I believe all dogs can be mean, but it depends on how you treat them. If they come from I good home then any breed of dog can be good would be just fine. If it comes from a bad home or whatever then the dog would probably have some problems. It’s all on the way you treat your pet and how you train it as well. I have a chow and lab mix loveable to everyone and I’m watching my step daughters pitbull loves everyone and well behaved. It’s all on how they are treated people.

This should be titled Stupid Humans

Sofia on February 19, 2019:

You are not who to say if a dog is ferousious or not. Each dog is different and they will grow to be different depending on the way you treat each one of them. I have a pitbull named lila and she is the sweetest thing ever with everyone. She is not "aggressive" or "feroucious" at all. This is not a reasonable article because you dont have any proof every pitbull will be the same or if every rotweiler will be the same. Every dog deserves a chance.

Doktor on February 17, 2019:

my mother raised a chow after its mother died when it was 3 weeks old it was a perfect companion for her. she loved that dog we thought it loved her until one day she reached to pet it. it bit her arm several time resulting in several stitches. that dog had seen it last sunset.

I agree that pit bulls are very dangerous

Hayden on January 31, 2019:

All dogs are good no dog deserves to be labeled ferocious

Donetta Sifford from Parrott, Virginia on January 29, 2019:

Hello I've read a lot of articles online listing the world's most "ferocious" dogs. A majority of these articles list the Great Dane as thr6mwe were you at the to

Allie on January 09, 2019:

U said pitbulls are mean have u ever had one cause i had one of she was so nice and loving she would never bite anyone one and then u said rattreweilweilers r mean i had and she was a baby and they can die easy she died at3 and i have one now and she is more scared of u than u are of her and then to top it of u said German Shepherds r mean my aunt has 1 and all she wants is a bone and her ball

Sparkles on December 30, 2018:

I agree with Scott. I am 36 and I have been raised with Boxers since I was a little over a year old. Every Boxer that has owned us (6 in all - because those of you that own Boxers know that's the case), has been super-loving, and while they may strike fear into the hearts of unexpected guests with their ferocious bark, every single one of them would have only been guilty of licking people to death, lol.

Dod on December 27, 2018:

This is awful. As many have already mentioned, any dog is capable of being dangerous with the wrong upbringing. We had a rescue lab that was very violent to other animals. We kept her in situations safe for herself and others and she was a wonderful and loyal sweet companion. We have a big rescue pit bull that loves my parents puppy. They roll around mouths wide open and tongues hanging out wrestling on the ground for hours.

Every dog is individual and has different histories. It’s our jobs as pet owners to responsibly raises them based on their personality traits and not show prejudice based on their breed.

Nikki P on December 17, 2018:

You have no idea what you are talking about. I have had 3 real authentic pit bulls 1 English bull dog and 1chow. People always want to say how mean these breeds are. That isn’t the truth. Maybe you should do some research. Pitbulls were first created as babysitters. Most people don’t know that but you can look it up. I have two small little girls. My dogs have never bit anyone or been in trouble what so ever. It is all about how you treat them and raise them. Now I will say if you mess with the owners of these dogs you have your hands full.

Dog Lover on December 02, 2018:

None of these dogs are vicious when loved and treated right. So, it's wrong too even have a sight that states these things. Because, that's how all dog are.

Randi on November 30, 2018:

This article makes me question three validity of everything else on this site. It really shows that you can say anything here without much knowledge or reason. All dogs can be vicious when treated to become that way. You're just perpetuating myths.

I have a pitbull and she is really nice but she doesn't do great with non submissive dogs but gets along great with my neighbors dog

Pit bulls for life on November 23, 2018:

I do not think pitbulls are vicious

I hardley think pit bulls are vicious.

People should stop being ignorant, stop criticising the author and read the article very carefully word-by-word so to speak. If you were paying attention when you wre reading you would have noticed these lines "These can be qiute gentle companions if you bring them up the right way." and this one "Not even a cat can beat a dog in being a man's best freind."

Only when provoked, treathened or not properly trained will these dogs endanger human life.

Im writing as a man whom has grown in a dog loving family. I have 5year old son and nine month old daugther.

Owning 4 dogs, 2 Rottweilers a 6year old and a 1yr old, 4yr old pit bull, 3yr old boerboel. they are all brothers and sisters. I have never had any problems with them in the same yard. they are well mannered and very well socialised. they are very good gaurds and family freinds. My 5yr old son can take the boerboel on a leash to buy some bread and there has never been incident.

People should stop mistreating dogs if they want them to be best behaved.

Muttine on November 09, 2018:

The big problem with pits is that most of them are bred and mixed with other unknown breeds. I'm pretty confident that most of the reported attacks are not from purebred pits. From what I understand, pits are often bred with more aggressive breeds like cane corso and bull terrier for "bloodsports". But, unless you have a licensed breeder, there is no way to know.

And yes, there are much more aggressive breeds than pits and rotts, but with such a powerful jaw like theirs the damage is much worst and often lethal. Owners should use their best judgment and socialize their dogs properly from when they are puppies or put a muzzle on during walkies to prevent incidents.

I rescued a lab/mastiff cross who was not socialized properly as a puppy and has anxiety towards noise and other dogs, however she is not aggressive at all. Still, I take precautions. She wears a harness during walks so I can control her, avoid interactions with dogs we don't know and we go out mostly when it's quiet outside. Her re-education is slow but we're making progress.

It's all about avoiding incidents and making sure everyone, including her, is safe.

Don't you hate when other dog owners just assume that you want their dog to come and snif yours? My shih-tzu got attacked by other toy breeds a few times in spite of me telling the other owner that I'd prefer if they didn't approach my dog. My dog is all friendly and their vicious little brat jumps him. Not cool.

thanks for not putting jack russel i get mad people think their bad plus i have one and i love her so much on November 05, 2018:

Debbie on September 15, 2018:

This makes me so angry!!!! NO dog is "ferocious" unless brought up that way!!!!

joe on September 05, 2018:

if German shepherds are number 4 then why do police use them...

i fostered a pit bull (mix) for a while, the only thing she was, was loving.

no i'm wrong she also killed a toad. the only other thing she could have done was lick somebody to death.

Marcus M on July 17, 2018:

Most of the dogs on this list are no where near "most ferocious". Aside from the Pitt bull, boerboels and cane Corso. The fact is when it comes to protective loyalty and ferociousness there are only two. The mighty Caucasian shepherd and the kangal! Anything else is just a dog. I see comments about how their German Shepherd is toughest and can handle any dog? Maybe at a suburban dog park. I've never seen a German Shepherd that could come close to my Caucasian male. Let alone my 135 lb rotties. During rough play my Caucasian has tossed 135lbs 5 ft in the air with no real aggression just a game. True story. Again this list is made up of Hollywood dogs. Surprised kujo wasn't number 1. Try harder with more research. Darn it I almost forgot the dogo argentino that could run through this list before lunch.

Libby on July 07, 2018:

I've had different breed of dogs.and pit bulls are the best dogs ever! they were the best dog nannies back in the days. They have a really good temperament. We shouldn't blame or tag the dogs when they get's how they were raised. Any dogs that have been treated cruelly and trained the wrong way obviously will turn out the way they knew and were taught how to act. However, if they were given and shown love, they will act right and give love and loyalty in return.

Ellie on July 07, 2018:

pit bulls are not even mean if y'all were nice to them and didn't abuse them then they are marshemmlows and are very loving and cute they only turned aggressive for self defense or if they are scared

Dog on June 24, 2018:

No dogs are dangerous! Any dog can attack! My dog was attacked by three different labs. I don't hate labs though. We just need good owners for every dog.

Joe on June 16, 2018:

I love boxers, pitbulls and I assure you pitbulls are the best breed being a family dog

Boxers? Boxers? Really? Only dangerous if they were to lick you to death!!!

Booya on March 16, 2018:

I have a 70lb American Staffordshire/ Lab mix and it is the most loyal passive dog I've ever had. He plays very well with dogs it has never met before. I love that I rescued him. He just wants to be loved.

Blanca on March 10, 2018:

How many years of personal experience do you have with each breed that makes you qualified to write this article?

TheChini on March 05, 2018:

Pitbulls are not mean dogs which is a common misconception. Pitbulls are companion dogs as well as very friendly dogs, but if mistreated will become dangerous, but that is only because they are scared and feel threatened. I have an American Pitbull and she is one of the nicest dogs I've ever seen. The only other reason people think they're dangerous is, because they were the dog breed that was in the military before the current dog breed and if you want to learn more about Pitbulls then watch a show called "Pitbulls And Parolees".

Rob Goodman on February 23, 2018:

if your dogs is smarter and stronger than you get a cat .Ignorance follows with bad problems

Jim Madden on February 22, 2018:

Totally surprised to see Boxers on the list of most dangerous breeds. My boxer lives to rough house with me. But has NEVER been hurtful.

i love pitbull

Mmac on October 12, 2017:

Chows should be on here.

Also People that say "pitbulls aren't agressive because I have one, she's cute and 6 mos old" are deluded and the type of owners that cause deaths at dog parks.

A sweet pitbull with humans/family can often turn on other dogs when the dog gives a small "warning growl" to back off.. (They have attacked mine - a sweet sheperd -and I've had to go break it up - always pitbulls and the owners always say the same thing- she's never done this etc)

Owners have to accept that the breed was bred to fight in a pit hence the name. Bred rom bulldogs who were bred to kill Bulls in a ring. They are naturally pre-disposed to aggression itv was bred into them. Not all are but a majority.

You cannot breed this out. you can somewhat control it but it the right situation it will always attack. The way a Beagle will ALWAYS chase a rabbit and and Aussie will always herd other dogs animals in a feild.

Owners need to accept the innate characteristics of these dogs and what they were bred for.
