International Dog Day is celebrated on August 26 every year to celebrate and respect every dog breed and to encourage dog adoption. No one can win our hearts as dogs do. We’ve compiled a list of worlds 6 most dangerous dog breeds, so if you see any of these listed dogs in angry mode, just stay away and behave calmly.
The essential characteristics of the American Pit Bull Terrier are strength, confidence, and zest for life. In the United States, German Shepherd is the second most popular dog breed, also known as Alsation.
American Bulldogs are a well-balanced athletic dog that demonstrates great strength, endurance, agility, and a friendly attitude.

The truth is, any dog can attack you. From the 6-pound Chihuahua to the 180-pound Saint Bernard, no dog breed comes with a 100% guarantee that it will not attack. However, the vast majority of dog attacks come from dogs that have not been well socialized.
However, most Pit Bull parents forget that proper socialization is what molded their pooch into a gentle soul. As a breed, Pit Bulls are the most dangerous dogs walking Gods green earth, and for a few reasons.
Moreover, Pit Bulls have the most lethal bite style of all dogs, holding, shaking viciously, and refusing to let go.

Image Credit: Miguel Santiago, PixabayAlso known as the Argentinian Mastiff, the Dogo Argentino is one of the few dogs that can give Pit Bulls a run for their money when it comes to sheer aggressiveness and tenacity.
In fact, this breed is considered so dangerous that it is banned in multiple countries, including Australia, Singapore, Ukraine, and the United Kingdom. Image Credit: patstatic, PixabayThere is a reason why movies typically use Doberman Pinschers when they want to cast a fearsome dog; the intimidation factor in this breed is really strong. Nonetheless, the Dobermans immense loyalty is what makes it so dangerous to other people, as this dog will not hesitate to attack anything it perceives as a threat to its kin.
As such, Dobermans require proper socialization and a confident, assertive handler since they will take matters into their own jaws if they detect uncertainty in you. Even after establishing your position as pack leader, the Akita cannot fathom the idea of coming second to another dog. Before you judge the Gull Dong too harshly, you should know that it was bred to be a fighting and hunting dog, meaning aggression and tenacity were highly favored traits when creating the breed.
Owing to their impressive size and intelligence, Perro de Presa Canarios are incredibly calm and self-assured, which is why they make excellent guard dogs. Nonetheless, their fearsome looks and reputation notwithstanding, Cane Corsos make excellent family pets.
It is hard to say that there are specific breeds of dogs that are dangerous. The way that a dog turns out depends on how the dog is raised, how he is treated, and his living conditions. That being said, there are some breeds of dog who are more prone to aggressive behavior than others. This doesnt mean in any way that these breeds are going to turn into aggressive dogs with a mean streak.
In 2016, an elderly man in Jacksonville, Florida was attacked by a pack of stray dogs, and at least one of them was identified as a Cocker Spaniel. Because this dog is so dangerous, it has been banned in several countries including the UK, New Zealand, Denmark, Norway, Hong Kong, Australia, and many others.
Since the ban has been placed on owning one of these dogs and because there are almost no breeders left, according to the ASPCA, there has only been one attack by this breed in the last three years. This breed of dog comes from the Italian and Swiss Alps and has become famous for his ability to rescue hikers who became stranded on the snowy mountains. If you want to keep a Saint Bernard from growing up and displaying territorial and aggressive behavior, you need to start socializing him with strangers and other animals at a young age.
In July 2016, a Canadian woman was walking by a bus stop when a Saint Bernard at the end of a leash began attacking her. He was originally bred to work on a farm where he would help his master catch and hold cattle and wild boar. The boy didnt make it and the owner was arrested for allowing the dog to get dangerously out of control.
On the other side of the spectrum, in May 2012, and American Bull Dog save a woman and a sleeping baby when an intruder entered the home. In 2015, a heroic American Bull Dog saved an entire family by keeping a murderer at bay until the police arrived. If these dogs get the love, attention, and training that they need, they will make a wonderful family pet.
This is the only dog on this list who can become aggressive and dangerous, even under the best conditions, only because he has the genetic makeup of a wild animal. Many states consider this breed, unacceptable, and they require that the owners carry a special insurance to cover any damage that these dogs can cause. On the other end of the spectrum, in October 2013, a Doberman Pinscher saved the life of a toddler after a venomous snake was ready to approached her in the garden.
According to the National Association of Dog Bite Statistics, over the past 15 years, the Husky was responsible for 15 fatal deaths. In 2015, a man in Jackson Madison County, Tennessee adopted a Rottweiler and three hours later, the dog attacked and killed him. In 2015, a woman named Kasha Weston was five months pregnant when a group of men with knives barged into her home.
While these dogs make great family pets, they need to be properly socialized and trained from an early age. If he is properly trained, loved, and cared for, he can be a great family pet, even in homes with small animals.
Are you are looking to get a new puppy to keep as a family pet and would like to know which breeds may not be the safest for children? In doing this research, I found that different organizations and “experts” have differing opinions as to which dog breeds are the most aggressive,” so I’ve listed the 10 that most sources seem to agree on below.
The causes of these behaviors can range from territorial defensiveness and protectiveness to fear and social anxiety. The 10 breeds listed below had some of the lowest overall passing rates in the temperament test conducted by the American Temperament Test Society and are sorted in order from lowest to the highest percentage of individual dogs that passed.
Breeds with the lowest passing percentages frequently showed signs of aggression, panic, or extreme shyness during the test. Chihuahua Dachshund Chow Chow Doberman Pinscher Dalmatian Rottweiler Jack Russell Terrier German Shepherd American Staffordshire/Pit Bull Terrier Siberian Husky They can be devoted to the point of jealousy and may bite or snip at individuals who come too close to their owner.
Dachshunds have strong hunting instincts, so those with small pets like rats or hamsters may want to consider another breed. Ranging in size from around 8 to 32 pounds, they can have long or short hair of just about any natural color. By the end of World War I, they were on the verge of extinction, but populations have since recovered, and they are now one of the most popular dogs in America.
Take caution with small pets, such as mice, rats, and hamsters, as Dachshunds have a strong hunting instinct toward this type of animal. They typically weigh between 45 and 70 pounds and have long, thick coats that can come in red, black, blue, cream, or cinnamon colors. The Doberman Pinscher is listed by the AKC as a medium-sized dog in the “working” group.
A man by the name of Karl Louis Doberman is credited with developing this German breed. He worked as a tax collector and wanted a dog that he could take with him for protection on his visits to the more dangerous areas to which he traveled. They range in size from around 45 to 60 pounds and have short, dense, glossy coats that are white with either black or brown spots.
Similar dogs are depicted running behind chariots in paintings found on the walls of some Egyptian tombs. They are good with children, but if not given enough attention by their owner, they can develop behavioral issues.They are very energetic dogs and require frequent opportunities to release some of this energy through exercise and play. They can range in size from around 85 to 130 pounds and are short-haired with straight, dense coats that are usually black with rust or mahogany markings.
In their earlier days, they were used for cattle herding and bear hunting, among other things. Later on, they became popular in the U.S. as guard dogs, and many worked with the army and police forces. They are normally good-natured with children, but because of their size and energy level, they are not recommended for families with infants or toddlers.
Jack Russell Terriers are stubborn and energetic, so they may not be the best choice for families with small children. The Jack Russell Terrier breed is not recognized by the AKC due to opposition from the breed’s parent society, the Jack Russell Terrier Club of America (JRTCA). The term “broken” refers to coats that feature both long and short hair.
Most experts recommend that families with young children choose another breed, especially if they are first-time dog owners. German Shepherds are very popular in the U.S. and frequently work as police or rescue animals. The German Shepherd is a medium-sized breed included in the “herding” group by the AKC.
They range in size from around 70 to 85 pounds and typically have a mix of brown, gray, black, and tan fur. During World War I, they were used as military dogs by both the German and French armed forces. Despite appearing on many “aggressive dogs” lists, everything I have read and experienced tells me that they are good with children.
As long as they are not trained as guard dogs, I personally do not view German Shepherds as an “aggressive” breed. American Pit Bull Terriers tend to get a bad reputation, but if properly socialized and trained, they can make great pets. The first strain of this breed was designed for use as guard dogs and for dogfighting, so they were bred to have stronger, stockier frames.
They are also known for being very good and patient with children, but if you are uncertain about a pit bull’s pedigree, do a background check before you choose it as a family pet. It will give you the real ins and outs of owning a Siberian Husky. Since the sample sizes differ dramatically, the resulting percentages may not fully represent each breed’s aggression levels.
According to the ATTS, the test “focuses on and measures different aspects of temperament such as stability, shyness, aggressiveness, and friendliness as well as the dogs instinct for protectiveness towards its handler and/or self-preservation in the face of a threat.” The test simulates a walk through the neighborhood where the dog encounters neutral, friendly, and threatening situations. A series of strangers approach the handler, and surprising noises are emitted from secret locations.
The test’s goal is to examine how the dog reacts to people, noises, and its surrounding environment. Because “strong avoidance” is considered a failure, the ATTS test may not accurately isolate the trait of aggression alone. The number of dogs tested per breed varies greatly, so the sample size isn’t consistent throughout the study.
Milan strongly believes that “the most dangerous dog in the world is the one that has been made that way by a human.” His view reflects the importance of seeking out the truth beyond mere numbers and statistics. So if a certain breed is commonly considered to have an “aggressive” personality, this could point to the type of person who tends to own that specific breed (e.g., German Shepherds are often owned by people who train them to protect property, hence their hostile behavior towards strangers).
I compiled the information in this article from a variety of sources and personal experience. Just because a certain breed has landed on this list does not mean it would not make a good family pet given the right owners and training. This content is accurate and true to the best of the authors knowledge and is not meant to substitute for formal and individualized advice from a qualified professional.
Then maybe all dog breeds will not be put on most aggressive, barks a lot or worst to potty train lists. I have a Jack Russell Terrier mixed with Chihuahua and a German Shepherd my babies are 2 and 9 years old. but when we out at the dog park so sweet they can be and they love children, my German shepherd his a baby himself that is my shadow wherever I go he’s there.
I have Progressive MS & she wakes me up for medication time, she reminds me to eat, she gets my clothes, helps me walk, she does my PT with me-makes me when Im not feeling up to it (the dr did it all around several dog type toys so its Our Play Time 2wc a day I just cant say no to those eyes that love & help me sooo much), she catches me before I fall, if I pass out she picks me up & puts me on my bed or couch & covers me up(staying by my side the whole time), she gets drinks & so many things for me, she goes out to dinner with me & use to go grocery shopping with me (I have someone else do that & order online now). Of course she was trained as a Service Dog, however, they didnt train her to catch me when I fell, or put me on my bed & cover me up, or tuck me up like a burrito & lay on me until I was done having a seizure so I couldnt hurt myself, or wake me up or alert me during the day when it was medication time….. so so many things my angel just decided she wanted to do for me out of pure amazing love Dobermans are not only one of the smartest dogs ( see the top 10 list on any website ) they are also one of the most loyal and protective.
(They’re called velcro dogs for a reason) I personally have never had an overly aggressive Doberman. However people do not get Dobermans, Rottweilers, Pitbulls, German Shepherds, etc because they want something cute and cuddly. The only reason Pitbulls are on here is because of there reputation i’m telling you now pits are big baby’s that love people and attention.
I have a jack Russel terrier mix he sleeps on pillows he is not any where close to aggressive. Firstly, surveys don’t exclude the people who’ve had bad pet experiences but comment sections like this do. To me all dogs can turn on u i have had dalmations that have turned min pins that have turned and several others that have done the same if i made this list chow chows would be number one and so on i dont trust that breed at all my papaw lived by sombody thag had two they bit several people and killed my papaws lil poodle in my papaws own yard there were times my pawpaw couldnt come out of his own house cause they were in the yard and trying to attack him….. Siberian huskys neber had one but my mom did when she married my dad and i was a baby i was told he was protective over me and would be very careful around me all around good dog never showed any aggression…. my mom owned a doberman as a kid and that dog was her best friend never bit her or anybody else in the house but showed aggression towards people she didnt know…. we had a cow dog when i was six and it was as mean as a rottweiler like we had to keep him in the bathroom when somebody visited and nobody could step out of their ride until we put him up a cow dog now …. heres my order of the most aggressive and this is my opinion and one of the breeds are a small breed 1.
I have never had the breed 3 i have a pit bull but hes mixed with lab and hes the sweetest thing u will ever meet will literally lick a kid to death he only shows aggression towards certain 4. We had two when i was eight and they were pretty aggressive towards strangers ome of them even bit me remember what i said up top about all breeds can turn we had these dogs since they we 6 weeks old and whem they got about 1 year old the male bit me for trying to get a sucker out of his mouth yea i know it was food but thats not the point 5. Now finally my favorite breed of dog i was raised aroud rottweilers from around 11 till i was sixteen and my stepdads brother who owned two fought them but guess what u messed with one of us kids and it was your ass they were the most sweet natured and down to earth dogs and smart as a whip the only thing that would make me hesitate in buying one is they keep a skin disease and they have breathing problems… so there u have it yes i do believe these most aggressive dogs do tend to turn more but when we hear these stories we dont get the whole truth we dont know what provoked that rottweiler or pitt to turn on its owner u think the owner is gonna tell u the whole truth about it naw they aint i believe amd this is my experience with these two breeds is that i bet alot of these cases the dog was either abused or mistreated something had to provoke these dogs to attack no animal not even rottys or pits are gonna turn for no reason i just don’t believe that mostly the only reason people fear pits is because of their jaw pressure which makes me hesitate but the pit i got and hes three years old i would trust with my life and any kids life hes loyal good guardian over me and my boyfriend and the only time he shows aggression is when he has to by like me being home by myself amd someone drives up but after he gets their scent hes goes back to his mellow self thats every dogs instinct u show these dog breeds alot of love and affection they will do the same back to u that’s just my opinion
Dachshunds, my parents owned them for years and bred them, as a kid they were my brother and my constant companions, and while I moved on to GSD’S my brother stuck with the Dachshund, I agree 100 percent with a couple of comments Dachy’s are the sweetest of dogs, they are willful and require consistent training, again it’s the owner not the dog, we have owned combined in our family from Collies (Scotch and Border) to Dachy’s to GSD’S and bitzas never had a bad one, one must ask why all our dogs have been great and TBH most peoples dogs are sweet and great and only a few a in the news for bad behaviour, the answer is simple it is the people who own them. Most of these comments are avidly argueing the same points that are made in the conclusion and saying how the author did bad reaserch or doesn’t know what they are talking about. There was this time when he bit a man walking behind us, that was really unexpected and happened so quick I could barely get him off!
After pulling my dog off him I apologized, and as soon as Ive tried to offer any help to the man he end up running. And till this day I dont know what caused my dog to react like that. For example, when I took my boy to the vet check up a veterinarian offered him a treat but he wouldnt even look at it or touch it!!
But he doesnt do that all the time, hes nearly 3 and after a bit of training his trauma seems to fade away and hes not as aggressive as he used to be towards other dogs. So you are NOT an expert in dog behavior you simply did a bit of googling to find what you have printed People get scared when they see him, but he had never ever shown aggression towards a human and he will wag his tale and go with anyone.
This study is bogus and these people should own these breeds before making a hasty decision. I had an American Pitt He loved people, big lap dog to everyone But, one day he killed one of our neighbors chickens and it never stopped. The whole thing of doing a background check of a pitbull before choosing it as a family dog is not true at all.
Sheila Brown has done her research and explained the criteria (the temperament test) she’s used to produce this list, but most of these posts are petty and biased… We get it – you love your dog breed – and that’s cool, but just because your mutt is harmless doesn’t mean the breed is suitable for an environment with children, unsocialized and untrained… get some objectivity people! You claim to be basing information on ‘other sources and first hand experience’ when all you have did to label these dogs as dangerous. I’ve had many of these breeds in my 60 years and never had an aggressive or bad dog, I’ve even had wolfdogs.
my pit bulls are great they get along with other dogs and kids no problem although they are huge And big headed make great pets they just look intimidating… and my bull terrier gets along with my pit bulls and great with people but just wants to kill any other dog or animal which just has to do with there breed… And my moms chihuahua horrible shes aggressive hates kids bites all of our dogs and friends for no reason shes a mini bomb and barks like crazy these dogs are not good for kids the only person that chihuahua likes is my mom… want a great dog get a pit bull they are intelligent protective and very tolerant with kids and animals I even bought one at 8 weeks to grow with son and she is a biter and is aggressive to strangers and doesn’t like cats. I trained my small children and grandchildren to leave her alone when she is under table sleeping or eating.
After I read most of the comments, I noticed that people have been saying, “It is not the breed that makes it aggressive it is how they are treated.” My friend owns a pit bull that is dog aggressive but raised vrry well. The American Staffordshire Terrier i find that very misleading they are considered nanny dogs because of how well they temperament is with children, i have one, he is the sweetest thing so your telling me there monsters but yet, he plays with kittens and ferrets all days and has a love for other animals.
I have owned a mini wire haired dachshund , a chihuahua and a Yorkshire terrier. I have a very large (80kg) German shepherd, who’s extremely friendly to people when we’re out for a walk, but very protective of the house and his “pack” when he’s at home. I had a standered wire haired dachshund Lola for 13 who had a lovely nature and was wonderful with children of all ages.
Studies have shown that it is poor socialization, abuse, neglect and un-neutered males cause 86% of dog involved fatalities. As pit bulls have a tendency to please their masters no matter what, aggressive and mean people tend to choose these breeds to please their ego and in many cases use them for their own purposes. Many countries have done a lot of work to restrict pit bull type dogs labeling them as dangerous and aggressive.
As a second time AST owner, I can say there is no sweeter, caring, kind and nurturing dog. People usually don’t go to a pet pyschologist to sort it out and dogs stay aggressive in similar circumstances. Being short in nature they tend to compensate it with higher aggressiveness, attacks etc.
Then there are all the people supporting them because they can get a “pit” pup for $40-100 at the flea market or off of sites like craigslist with no clue as to the personality traits or temperment genetically. These people also tend to be younger and/or inexperienced dog owners that are not ready for what it takes to own a highly intelligent and often quite stubborn breed that can make every single thing a battle of wills if you give in even once, they will expect you to give in again. The best thing people can do is research the breed you are interested in and what it takes to work with them, then to adopt from a rescue or shelter.
Even small dogs like Chihuahuas should be held to the same standard and can be well rounded and well behaved if care was taken in selecting the parents and the pup is raised properly including training, socialization… And most importantly, like a dog! My daughters chi is the perfect example of how wonderful they can be personality wise if care was taken on where they came from and how they were brought up. I respect your article but Im a owner of Doberman all my life never had a issue I believe as long we treat are doggies with love
We had a rabbit that would climbed all over him that we got when he was older and he never bit him…..he would growl at him and throw him, because the rabbit wouldnt leave him alone and then just get up and walk into my room and close my door, my daughter was also around him in his older age and she did what she wanted to him. I absolutely agree with you on Pitbulls and all other breads labeled “Most Aggressive or Dangerous” dogs. And all my dogs were loving and excellent with people and all children, but Boston Police always stereotyped them!
This is a breed that in Victorian times was the nanny dog, chosen to watch over children. With the rise of a culture of gangs, illegal drugs etc, the pit bull became the dog of choice for the lowest members of society. Abusing the breeds traits of strength, loyalty, protectiveness, and territoriality, the pit bull has become the most bred dog in America.
Dogs from professional breeders who care and take time to find the right match for breeding rarely have aggressive dangerous pups. Pits are people dogs and leaving them chained or alone in a yard is heartbreaking to them. Pits require a strong owner who will be the alpha in the relationship, setting boundaries, etc.
If the owners arent capable of being a benevolent leader the dog will take matters into his own hands. I love pits and I think BSL is useless, damning good dogs. Dogs are registered every year with the govt and transfer of ownership is greatly restricted.
Germany isnt euthanizing over a million pit bulls every year like the US. I hate the way the pit bull has been corrupted, turned into weapons for the baser elements of society. But the chance of being bitten by a bully belonging to a responsible owner is 1000 times less than a bite from a dachshund, chihuahua, or any number of the smaller but more aggressive breeds.
Im active in rescue and have owned up to 8 dogs at a time of diverse breeds– Dachshund, Chi, Dane, Poodle, Beagle, Flat Coat Retriever, Coonhound, Border Collie, Staffy to name a few. My experience has been that it is almost impossible to find a dog or human aggressive Coonhound, Beagle or Flat Coat. Sweet, playful, stoic with overly rough children, yet still protective of home and family if threatened.
Recently my 13 yr old Staffy, with terminal cancer, fought off 3 coyotes in my yard when she & Border Collie were attacked. BC ran, Staffy sustained severe bites but chased off coyotes. Ive even dealt with Pit Bulls that had been fighters and everyone was loving and gentle with people.
As a breed they are incredibly resilient physically and emotionally, able greet people with wagging tail and bully grin even after the most horrible abuse. This was a very comprehensive article and the author deserves credit for backing up her findings with real statistics. However, what I will say is that EVERY single dog breed can be aggressive without proper care and training.
If you’re unsure about how to train a calm, obedient dog there are some really helpful video tutorials at: http://www.dansmethod.com – It’s just a matter of patience and consistency. Im actually surprised and happy bull terriers are not first on this list and how less than half of them came up as aggressive! He can be a little aggressive when he is playing.nhe is fairly new and I was wandering the best way to train him to sit stay and not run away when were taking a walk.
As someone who worked as a vet tech for 15 years I agree with most of the dogs on this list, especially the chihuahua, Dalmatian, chow, rottie, and husky. My husband wants to bring home a young Jack Russell Terrier.
1. American Pit Bull Terrier
If you ask a responsible Pit Bull owner whether their dog is dangerous, they will tell you that it is a misconception and that Pit Bulls are the sweetest dogs in the world. However, most Pit Bull parents forget that proper socialization is what molded their pooch into a gentle soul.As a breed, Pit Bulls are the most dangerous dogs walking God’s green earth, and for a few reasons.Pits can pose a substantial threat to those around them because many were selectively bred for dogfighting. As such, traits such as aggression and tenacity were highly favored and run in this breed’s blood.Moreover, Pit Bulls have the most lethal bite style of all dogs, holding, shaking viciously, and refusing to let go. This explains why most Pit Bull attacks result in gruesome injuries or even death.
The Rottweiler is renowned for its extreme bouts of aggression. Unfortunately, their fearsome reputation is not without merit, as an unhinged Rottweiler is an absolute terror.However, Rottweilers are incredibly calm and docile around their family. Their mean streak only surfaces when an unfamiliar individual is around them or their loved ones. It makes sense since Rottweilers were bred to be guard dogs.As such, early socialization is crucial for Rottweilers.
3. Dogo Argentino
Also known as the Argentinian Mastiff, the Dogo Argentino is one of the few dogs that can give Pit Bulls a run for their money when it comes to sheer aggressiveness and tenacity. In fact, this breed is considered so dangerous that it is banned in multiple countries, including Australia, Singapore, Ukraine, and the United Kingdom.The Dogo Argentino was bred to hunt big game and protect its family. As you can imagine, traits such as aggressiveness, gameness, and raw, unbridled power were highly favored when designing this breed, which is why you must socialize them early to keep those traits in check.
4. Doberman Pinscher
There is a reason why movies typically use Doberman Pinschers when they want to cast a fearsome dog; the intimidation factor in this breed is really strong.The Doberman Pinscher not only looks the part but also plays the part, as it is one of the most aggressive dog breeds in the world. However, Dobermans can be remarkably sweet to their family, as they were bred to be guard dogs.Nonetheless, the Doberman’s immense loyalty is what makes it so dangerous to other people, as this dog will not hesitate to attack anything it perceives as a threat to its kin. As such, Dobermans require proper socialization and a confident, assertive handler since they will take matters into their own jaws if they detect uncertainty in you.
Strong-willed, powerful, and with a need for independence, the Akita is not a dog for amateurs. Due to the Akita’s dominant personality, this dog is always looking to become the pack leader. This is why it is not an ideal breed for first-time dog owners.Even after establishing your position as pack leader, the Akita cannot fathom the idea of coming second to another dog. This trait makes Akitas highly territorial and aggressive to other dogs and people outside of their family.Therefore, you will need to be vigilant when your Akita is around unfamiliar people or dogs.The dog is also extremely protective of its food, reacting aggressively to anyone who comes close while it is eating. Fortunately, Akitas make excellent pets with proper training and socialization.
6. Gull Dong
The Gull Dong is among the rarest dog breeds in the world, and with good reason, they do not make good family pets. This Pakistani dog breed’s grumpy attitude makes it highly unpredictable—these dogs have been known to even turn on their owners. They are also difficult to train.Before you judge the Gull Dong too harshly, you should know that it was bred to be a fighting and hunting dog, meaning aggression and tenacity were highly favored traits when creating the breed.
7. Perro de Presa Canario
To be fair, the Perro de Presa Canario is not aggressive by nature. Owing to their impressive size and intelligence, Perro de Presa Canarios are incredibly calm and self-assured, which is why they make excellent guard dogs.However, when a Perro de Presa Canario is around unfamiliar people or animals, it becomes a danger. This breed is not only extremely suspicious of strangers but also has an exceedingly high prey drive. As such, it can attack without warning, causing great damage.Therefore, early training and socialization are necessary for Perro de Presa Canarios. Moreover, this dog requires lots of exercise and stimulation to prevent destructive behaviors.
8. Tosa Inu
The Tosa Inu is another rare breed due to the nasty reputation that precedes it. Tosa Inus are native to Japan, where they were bred as fighting dogs.Most Tosa Inus are unhinged, to say the least, as cases of these dogs turning on their owners are common. It also does not help that the Tosa Inu has one of the most powerful jaws in the canine kingdom.As you can imagine, they do not make good family dogs.
9. Chow Chow
The Chow Chow might look like an overgrown teddy bear; however, this dog is anything but that when it comes to personality. Chows Chows are not only dangerous but also ready and willing to demand your respect at any cost.These dogs have been known to turn on their owners simply because they do not feel like doing what is being asked of them.Chows Chows are also lazy and can be irritable and intolerant of strangers. As you can imagine, this breed requires an owner with a strong, calm, and assertive personality; otherwise, it will walk all over any other kind of personality.
10. Cane Corso
To cap off this list, we have the Cane Corso. This beast of a dog was bred for fighting and catching mountain lions and boars. Think about that for a second; the Cane Corso was bred to catch other predators! If that is not the epitome of a dangerous dog, we do not know what is.Nonetheless, their fearsome looks and reputation notwithstanding, Cane Corsos make excellent family pets. This is because the Cane Corso is self-confident, meaning that it does not feel the need to throw its weight around. Nonetheless, early socialization is necessary.
How Canine Aggression Is Defined
Dog aggression is typically defined as dangerous behavior directed at another individual (like a human or another dog). Aggressive behaviors include barking, biting, lunging, snarling, etc. The causes of these behaviors can range from territorial defensiveness and protectiveness to fear and social anxiety.
2. Dachshund (Standard Smooth)
The Dachshund is categorized as a member of the “hound” group by the AKC. Ranging in size from around 8 to 32 pounds, they can have long or short hair of just about any natural color.They originated in Germany in the 17th century and were used primarily to hunt badgers. By the end of World War I, they were on the verge of extinction, but populations have since recovered, and they are now one of the most popular dogs in America.The Dachshund is susceptible to “small dog syndrome,” which basically means that it often tries to make up for its small size with a large attitude. This can lead to a variety of behavioral issues. If socialized at an early age, they can do well with children, but they do not enjoy rough play. Take caution with small pets, such as mice, rats, and hamsters, as Dachshunds have a strong hunting instinct toward this type of animal.
3. Chow Chow
The Chow Chow is listed as a medium-sized dog in the “non-sporting” group by the AKC. They typically weigh between 45 and 70 pounds and have long, thick coats that can come in red, black, blue, cream, or cinnamon colors.The exact origin of the Chow Chow is unknown, but it is believed that they originated thousands of years ago in either China or Mongolia where they were most often used as hunting and herding dogs. They became popular in the U.S. during the 20th century when President Calvin Coolidge kept one as a pet.

Chow Chows tend to have dominant personalities and can become assertive at times. Because of their assertiveness, they are not recommended for first-time dog owners.
4. Doberman Pinscher
The Doberman Pinscher is listed by the AKC as a medium-sized dog in the “working” group. They range in size from around 70 to 90 pounds and have thick, glossy, short-haired coats that come in red, black, blue, or fawn colors.A man by the name of Karl Louis Doberman is credited with developing this German breed. He worked as a tax collector and wanted a dog that he could take with him for protection on his visits to the more dangerous areas to which he traveled.Dobermans are very intelligent and have been widely used as guard dogs and for police work. They have a very strong, protective instinct towards their masters, but if raised with strong leadership and good owners, they can get along with children as well as other dogs.
The Dalmatian is listed by the AKC as a medium-sized dog in the “working” group. They range in size from around 45 to 60 pounds and have short, dense, glossy coats that are white with either black or brown spots.The exact origin of the Dalmatian has not been confirmed. Similar dogs are depicted running behind chariots in paintings found on the walls of some Egyptian tombs. Since the late 18th century, they have been used as carriage dogs to guard passengers and cargo.Dalmatians need to be socialized at an early age. They are good with children, but if not given enough attention by their owner, they can develop behavioral issues.
The Rottweiler is listed as a large-sized dog in the “working” group. They can range in size from around 85 to 130 pounds and are short-haired with straight, dense coats that are usually black with rust or mahogany markings.The Rottweiler gets its name from the small town of Rottweil in Germany. It was first known as the “Rottweil butcher’s dog,” but the name was later shortened to Rottweiler. In their earlier days, they were used for cattle herding and bear hunting, among other things. Later on, they became popular in the U.S. as guard dogs, and many worked with the army and police forces.Rottweilers can be rather aloof and do not usually get along with strangers easily. They are very loyal and protective of their owners, and they tend to defend their home areas. They are normally good-natured with children, but because of their size and energy level, they are not recommended for families with infants or toddlers.
7. Jack Russell Terrier
The Jack Russell Terrier breed is not recognized by the AKC due to opposition from the breed’s parent society, the Jack Russell Terrier Club of America (JRTCA). This has resulted in the recognition of the Parson Russell Terrier instead. The Jack Russell terrier and Parson Terrier are basically the same breed, but there are some minor differences.Jack Russells are small-sized dogs that range in size from around 14 to 18 pounds and are predominantly white in color with black or tan markings. Their coats can be short-haired, long-haired, or broken. The term “broken” refers to coats that feature both long and short hair.Jack Russells originated in England where they were primarily used for fox hunting, but they have also been used in groundhog and badger hunting.Russell Terriers tend to be very energetic and stubborn dogs. They have little patience and are not known to be very tolerant of children. Most experts recommend that families with young children choose another breed, especially if they are first-time dog owners.
8. German Shepherd
The German Shepherd is a medium-sized breed included in the “herding” group by the AKC. They range in size from around 70 to 85 pounds and typically have a mix of brown, gray, black, and tan fur.The breed originated in Karlsruhe, Germany, in the 1800s. During World War I, they were used as military dogs by both the German and French armed forces. They are a very intelligent breed and were the first to be used as guide dogs for the blind. They are also used in search-and-rescue teams and frequently serve as police and narcotic dogs.The German Shepherd has become one of the most popular dogs in America. They tend not to like strangers, so they make good guard dogs. Despite appearing on many “aggressive dogs” lists, everything I have read and experienced tells me that they are good with children. As long as they are not trained as guard dogs, I personally do not view German Shepherds as an “aggressive” breed.
9. American Staffordshire/Pit Bull Terrier
The American Staffordshire Terrier, also known as the American Pit Bull Terrier,They originated in the Staffordshire region of England, hence the name. The first strain of this breed was designed for use as guard dogs and for dogfighting, so they were bred to have stronger, stockier frames. When the breed was brought to America and dogfighting was banned, a second strain of this breed developed. This new variation was more mild-mannered and smaller-framed. Known as the American Pit Bull, this newer strain of pit bull is very loyal and protective of its owner and family.They are also known for being very good and patient with children, but if you are uncertain about a pit bull’s pedigree, do a background check before you choose it as a family pet.
10. Siberian Husky
The Siberian husky is a medium-sized dog listed in the “working” group by the AKC.They originated in Siberia, where they were used to pull sleds over long distances in cold climates. They have also been used as rescue dogs.Through my research—and my experience owning four Siberian huskies—I cannot find definitive studies that prove huskies have aggressive personalities, but they have appeared on many lists of aggressive dogs, which is why they are on this one. From my experience, huskies do tend to be territorial and do not always get along well with other dogs, but they are usually good with children.If you plan to adopt a husky, I recommend this interesting and informative book. It will give you the real ins and outs of owning a Siberian Husky. They are definitely a high-personality dog breed, and they are also my personal favorite!
The Takeaway: No Breed Is Inherently Vicious
I would take the percentages provided by the American Temperament Test Society with a grain of salt because the number of dogs tested per breed is not the same. For example, when conducting the aggression test on the Rottweiler breed, over 5,000 Rottweilers were tested, while only 46 Chihuahuas were put through the same test. Since the sample sizes differ dramatically, the resulting percentages may not fully represent each breed’s aggression levels.According to the ATTS, the test “focuses on and measures different aspects of temperament such as stability, shyness, aggressiveness, and friendliness as well as the dog’s instinct for protectiveness towards its handler and/or self-preservation in the face of a threat.”The test simulates a walk through the neighborhood where the dog encounters neutral, friendly, and threatening situations. A series of strangers approach the handler, and surprising noises are emitted from secret locations. The test’s goal is to examine how the dog reacts to people, noises, and its surrounding environment.The percentage listed under each breed indicates the number of dogs that passed the temperament test divided by the total number of dogs tested for that breed. 46 Chihuahuas were tested and 14 failed, so the passing percentage for Chihuahuas is the number of dogs that passed (32) divided by the total number tested (46), or 69.9 percent.Failure is determined when a dog shows any signs of the following:
