How I Determined Which Dog Breeds Are the Most Dangerous

In doing my research, I have found that different organizations and different “experts” have their own opinions as to which dog breeds are the “most aggressive." The ratings also vary.

The dogs on this list are sorted in order of lowest to highest percent of dogs that passed the temperament test conducted by the American Temperament Test Society. Breeds with the lowest percentages are ones that frequently showed signs of aggression, panic, or extreme shyness during the test.

While there are breeds with even lower percentages than the ones mentioned in this article, I've decided to limit the list to 10 breeds that are most frequently ranked as highly aggressive (i.e., these are breeds that are most commonly considered "aggressive" or "dangerous" and/or are included on breed-specific legislation).

Definition of Dog Aggression

Dog aggression is defined as dangerous behavior directed at another individual, including other animals. This behavior includes barking, biting, lunging, snarling, etc. The cause can range from territorial defensiveness and protectiveness to fear or social anxiety.

Chihuahua

1. Chihuahua

  • The chihuahua is the smallest breed of dog registered with the American Kennel Club. They are also known as being the smallest dogs in the world.
  • They are included in the toy group of dogs and range from 4 to 6 pounds.
  • They can have either short or long hair.
  • The chihuahua can come in just about any color, and their coloring can be either solid, marked, or splashed.
  • The chihuahua is considered to be the oldest dog breed in America.
  • The breed originated in the Mexican state of Chihuahua, thus its name. It was introduced in Europe by the famous explorer Christopher Columbus.
  • Chihuahuas are very loyal and devoted to their owners, but they are generally one- or two-person dogs. They can be devoted to the point of jealousy and may bite or snip at someone coming too close to their owner. They are very temperamental and are not known to be child-friendly dogs.
  • Because they do not like strangers, they bark often and can be good as an alert-style watch dog.

2. Dachshund (Standard Smooth)

  • The dachshund is categorized in the hound group by the AKC.
  • They can range in size from 8 to 32 pounds.
  • The dachshund comes in both long and short hair and can be any color.
  • This small dog breed originated in Germany in the 17th century, and they were used primarily to hunt badgers. They were on the verge of extinction after World War I but are now one of the most popular dogs in America.
  • The dachshund is susceptible to "small dog syndrome," which basically means that it tries to make up for its small size with a large attitude. This can lead to behavioral issues.
  • If socialized at an early age, they do well with children, but do not do well with too much rough play.
  • Take caution with small pets, such as mice, rats, hamsters, as dachshunds have a strong hunting instinct towards this type of animal.

  • The chow chow has a dominant personality and can become assertive at times. Because of their assertiveness, they are not recommended for first-time dog owners.
  • Strong guidance and firm training are required to have a well-mannered chow chow.
  • It has also been noted that they do not have good peripheral vision, so they can be easily startled.

  • The Doberman is a very intelligent breed and has been used mainly 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 can be reserved with other dogs and needs to be socialized at an early age.
  • They are good with children, but if not given enough attention by their master, they can develop some behavioral issues.
  • They are very energetic dogs and need a good place to release some of this energy.

  • They became popular in the U.S. as guard dogs and worked with the Army and police forces.
  • Rottweilers can be rather aloof and do not accept strangers easily.

7. Jack Russell Terrier

  • The Jack Russell terrier breed is not recognized by the AKC due to opposition of the breed's parent societies. This has resulted in the recognition of the Parson Russell terrier instead. The Jack Russell terrier and the Parson terrier are basically the same breed but with minor differences.
  • Jack Russells are small-sized dogs and range in size from 14 to 18 pounds.
  • They are predominantly white in color with black or tan markings.
  • Their coat can be short-haired, long-haired, or broken. The term “broken” refers to a coat of both long and short hair.

8. German Shepherd

  • The German Shepherd is a medium-sized dog included in the herding group of the AKC.
  • They range in size between 70 and 85 pounds.
  • The breed's origins can be traced back to Karlsruhe, Germany in the 1800s.
  • During WWI, they were used as military dogs by both the German and French military.
  • They do not like strangers, and therefore make good guard dogs.
  • They are a very intelligent breed and were the first to be used as guide dogs for the blind.
  • They are often used in search-and-rescue teams and also serve as police and narcotic dogs.
  • The German Shepherd has become one of the most popular dogs in America.

*Despite appearing on many "aggressive dogs" lists, everything I have researched tells me that they are good with children. As long as they are not trained as guard dogs, I, personally, do not view the German Shepherd as an “aggressive” breed.

9. American Staffordshire/ Pit Bull Terrier

  • The American Staffordshire terrier is also know as the American pit bull terrier.
  • They are medium-sized dogs included in the terrier group and can weigh between 55 to 65 pounds.
  • The American Staffordshire terrier originated in England, in the Staffordshire region, thus its name.
  • The first strain of this breed was designed for use as guard dogs and dog fighting, and they were bred for stronger, stockier frames. When the breed was brought to America and dog fighting 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.
  • 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 range in size from 35 to 70 pounds.
  • The have medium-length hair and a double coat.
  • Their colors are red and white, black and white, gray and white, or silver.

*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.

Understanding the Results of the Temperament Test

I do not fully agree with the percentages provided by the American Temperament Test Society 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. Therefore, the percentages cannot fully represent the aggression level of an entire breed.

How the Test Is Conducted

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. This is conducted with a series of different strangers approaching the handler, as well as a number of hidden noises. The goal of the test is to examine how the dog reacts to people, noises, and its surrounding environment.

How the Passing Rate Is Determined

The percentage listed under each breed indicates the number of dogs that have passed the temperament test based on the total number of dogs tested for that breed. If there were 46 dogs tested for the Chihuahua breed and 14 of those dogs failed, the percentage would be the number of dogs that passed (32) divided by the total (46), which yields a 69.9% passing rate.

Failure is determined when a dog shows any signs of the following:

  • Unprovoked aggression
  • Panic without recovery
  • Strong avoidance

Shortcomings to Consider

  • Because "strong avoidance" is considered a failure, the ATTS test may not be an accurate measure of aggression alone.
  • The number of dogs tested per breed varies greatly, so the percentages may be skewed.

A Divided Debate: What Is the Most Dangerous Dog Breed?

There are many dog trainers who, when asked what the most aggressive dog is, will not respond with a specific breed. Celebrity dog behaviorist Cesar Milan is one such person who is against breed-labeling. 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. Anyone who has owned a pit bull — a breed notorious for viciousness — can attest to the pit bull's gentle, if not overly-affectionate behavior when it is raised with love and care by its owners.

Dogs are a reflection of their family environment and training, so if a certain breed is commonly considered to have an "aggressive" personality, it 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).

Conclusion

Again, this is information that I have compiled from many sources, as well as from personal experience. Just because a certain breed has landed on this list does not mean that they would not make good family pets given the right owners and training.

Because training (or lack of training) and how the dog was previously treated can make a huge difference in the personality of any dog, doing some type of background check would be a good idea.

        I have a Doberman as a service dog, and had a pit bull who is now passed on. Both are (and were) fine with everyone and love other dogs as well, the pit bull even would baby my pet rat and watch over it. Being gentle and bathing it with licks. The Doberman we started out with him at three months old and exposed him to everything. I would also have them come with me to the door, too see not everyone that comes in the property is a dangerous threat, be it the owner (me) is allowing them in or excepting of the stranger just being st the door. It just takes training, socializing and love to get an “Aggressive” breed to be friendly and excepting of others. Sadly, most people don’t want that and aim for the vicious and dangerous behavior cause it makes them seem cooler or tough to own a dog like that...

        I have had 7 of these dog breeds myself, and if i extend out to immediate family, that number goes up to all 10. Based on my personal experience with multiple doga of almost all breeds you listed i have to say you only got three of them right. The Chihuahua, dachshund, and dalmatian are the only dogs on this list that are actually aggressive by nature. For the rest you have confused these dogs breeds peotective natures with agression. I currently have a doberman and a rottweiler, sister has two american Stratfordshire terriers, my dad had a german shepherd, my son's grandpa has a jack russel terrier, my mom has a Chihuahua, my dads wife has two dachshunds, and my grandpa has a dachsund. The only ones that show unbiased aggresion are the Chihuahua and the dachshunds. Those dogs, however, are alos the dumbest things i have ever met, except for the dalmation that my dad had when i was 5. The dalmation also was the meanest dog i have ever met. I think your list is based less on fact and more on opinion.

        I disagree with this article first off a dog is aggressive because of the owner and I have one of the most aggressive dogs but really he’s a sweetheart he likes to cuddle to play he never bites he is a pit bull and same with my German Shepherd they are harmless dogs and you should never be afraid of them they are sweeties and they would never hurt anyone on purpose it’s a human that makes them aggressive And yet pitbull’s are the first ones to be put down and then it’s the bigger dogs in the bigger dogs I disagree with this all dogs are sweet on the inside it’s just a human that makes them aggressive and most of the time it’s a criminal

        I don’t agree with the ol “no bad breeds just bad owners”— any dog can flip out and attack for unknown reasons- even those raised well! When a chihuahua flips out you can easily restrain him. When a pit flips out, a person can be mauled to death. That’s the difference.

        There are no bad dogs - just bad owners. Granted, thugs, drug dealers, and criminals don't usually keep Old English Sheepdogs but if they did - you can bet they'd be on the "Dangerous Dog" list too.

        While there are some dogs that just have an unstable temperament because of breeding.

        For example, Chows were a food source - so not bred for temperament; Presas and Tosas were bred for dog fighting - so again issues arise; but generally, dogs just want dinner and a hug.

        I find this test invalid as they had not studied the human interaction with these dogs. If the human does not provide proper discipline, instruction, and love, the dog will take the leadership role. If one is going to take on any dog, proper instruction should be undertaken. Basic classes should be either offered or shown as available before the adoption process. These should be as important as spaying or neutering. Please, remember these are dogs and NOT little humans. They are not your children, but your companions.

        I think it would be wise to compare these breeds with others. For example, "pit bulls" (it's a blanket term, as it covers several breeds), score just as high as Golden Retrievers. I mention pit bulls because they're the most demonized breed currently (it was other breeds before...it's always some breed).

        Anonymous, the reason people are getting "butt hurt" is because of misinformation & stereotypes there exists such a thing as Breed Specific Legislation (BSL). People behind this don't care how nice YOUR dog is or what YOU think, they put ALL dogs of a breed THEY consider "aggressive" under the legislation & these dogs either have to be rehomed or are destroyed!

        As I mentioned, pit bulls are currently demonized. Many people wouldn't know an American Pit Bull Terrier (APBT) if they tripped over it. Many people on Facebook, for example, say that the lean, smaller dogs aren't APBT's & call dogs that are actually American Bullies APBT's instead. Sorry for them, but the leaner, smaller dogs are the original APBT, NOT the bullier type you see today (an American Staffordshire Terrier would be "bullier" looking for example, but an American Bully is moreso).Take "find the pit bull" tests online; many, many people fail them, including professionals.

        Even the info. in this article is incorrect. The APBT is the true pit bull, not the American Staffordshire Terrier (AST). The AST also

        originated in America, not the Staffordshire area of England. The Staffordshire Bull Terrier originated in that area, thus THEIR name. They all fall under the "pit bull" moniker, but are two different breeds. The original was the APBT, not the AST. The APBT & the AST were the same breed until 1936, as they'd been bred in two different directions, the AST being a bulkier dog, not a smaller dog as the article mentions. The smaller framed dogs were first, then the larger framed dogs. APBT's weigh less than AST's, so the weight listed is even wrong. Pit bulls were also not used as guard dogs, as a matter of fact, true APBT's usually make poor guard dogs for property; they will protect the family, but if the family isn't present you can make off with the silverware. There were man biting fighting APBT's, but they were frowned upon, so not common, as the dog's owners had to wash the other owners dog before a fight (no, I don't condone it, it's just part of the past history of the breed...and no, dog aggression doesn't equal human aggression either). I mention the inaccuracies, as it's important to have the proper info. because, as I said, many people wouldn't know an APBT if they tripped over it and therefore, inaccurate identification furthers BSL.

        The problem is that when a breed becomes popular, as the APBT did after a magazine's article on them that confused dog aggression with human aggression, they become overbred by people looking for certain traits, in this breed's case, "tough" dogs. German Shepherds, Dobermans and Rottweilers (as well as other breeds before them) suffered the same. Dogs also become popular due to movies. Dalmations were overbred after 101 Dalmations, Cockers after Lady & the Tramp, Collies after Lassie, etc. Golden & Labrador Retrievers, being known as ultimate family dogs, because of that being said have been overbred & are now suffering a lot of aggression issues, especially among the Labs.

        I don’t get why people are getting all butt hurt yes it maybe be your dog breed getting talked about but is it your dog specifically? No. Your dog can be nice as can be and as loyal as it can that doesn’t matter. This is just simply putting the dogs lowest passed percent rate of the test that was done.

        Yes it may be making people think twice about your dog breed but who cares as long as you are happy? Not everyone is going to agree on dogs behaviors due to one person may have say a pug that’s kind as can be and one person may have gotten attacked by one And now are fearful of it but oh well that’s their decision no one can change that but them. And every dog breed has there ups and downs And Some more then others because they are more common. But overall it matters what YOU think of the breed no one else don’t try to put it on others because they don’t like something you do.

        I completely disagree that Dobermans are that aggressive. I know many Dobermans and they, including mine, are cupcakes.

        A little stand offish at first, but friendly once he gets to know you. Poodles are WAY more aggressive.

        There’s really one main factor when trying to determine if a breed of dog is genetically predisposed towards being aggressive. What were they bred for? Australian Cattle dogs are beautiful, but boy can they drive you nuts with the barking and attempting to take charge and herd everyone in the family! So look into the history of the breed. Don’t just choose an animal because they look adorable, or tough.

        Now here are two immediate factors to consider that do not necessarily involve breed.

        1. Intelligence: Fact is you cannot get a read on a dumb dog. You’ll be happily petting them, and with no forewarning you’re suddenly getting bit. Intelligent dogs will give you signs that you are doing something they don’t like, or if they’re getting stressed.

        2. Training/Abuse: Common sense should tell you not to run up and hug the Police dog. Abused animals also generally do not take well to being run up to. Now combine abuse and training and you suddenly get a misconception about an entire bred. For those of us old enough to remember, there was a time when Rottweilers were the breed to fear. So much so that they where banned from many places. They were the dogs used for fighting and other unsavory things. Statistics show between ‘93-‘96 the were responsible half the deadly dog bites. After it becomes difficult to own a Rottweiler, the Pit Bull filled the void. Don’t be shocked to hear that they are now attributed to half of the fatalities.

        I cannot emphasize enough, before you get an animal do your research!

        I found this article to be very interesting. I have always thought pit bulls get a bad rap. My son has one, and he is a wonderful loving dog. I was surprised to see the Jack Russell on the list. I have never owned one, but another family member has had two of them and I haven't heard of any aggression. As you said, I think it all depends on their training, just like it does with children!

        I have a 7 year old rottweiler and an 11 year old miniature dachshund so by all accounts my house should be a no go zone with snarling and snapping teeth :)

        Admittedly if you are on the outside of the gate the rottweiler (Shakira) will let you know that you are not welcome, but if my wife or I open the gate and let you in personally then she immediately warms up and gives you a few good hard sniffs and you're good to go! She is very protective of our 5 year old daughter, if we are not at home and the baby sitter or even grandparents is with her she sometimes follows them both around the house or will sit outside of her room!

        But all-in-all both of them are excellent family dogs, I wouldn't change them for the world and neither would my wife or daughter :)

        Accuracy Matters

        I have a nine-year-old Doberman. She absolutely loves people and will lean on total strangers, smiling up at them, and hoping that they'll pet her. Her temperament is stellar, and she speaks "dog" fluently in any dialect. Small dogs seem to love her. They tend to follow her around. When she broke her toe as a puppy, the daycare she went to put her in with the small dogs so that she wouldn't be too active while her toe healed.

        Since I've had my girl, I've met hundreds of Dobermans. One of my favorites is an eight-year-old male that loves playing with puppies and younger dogs. They're beautiful to watch, prancing around like little horses.

        While most Dobermans do like to play rough, the Dobermans all seem to know their size, and they're gentle with the younger or smaller dogs and only play rough with others that like to play rough. It's fascinating to watch. I mention this because it seems like some dogs like to "torture" younger dogs, but I've never seen a Doberman do this. I have to add that some of my girl's best buds have been sweet Pits.

        As for aggressive, the small Poodle mix next door goes after my girl and has bitten her on occasion. One minute he was sweet as can be, and the next thing you know, he's biting her. These days, my girl starts shaking and runs away as fast as she can when she sees him. Why aren't Poodles on the "aggressive list"?

        I've seen all kinds of dogs bite other dogs, but never the Dobermans. Even as puppies, I've only known them be 100 percent respectful to other dogs. The worst offenders in my own world have been Golden Retrievers, and no one would think of putting them on an "aggressive list."

        I don't personally know anyone that has a Doberman as a guard dog. I can't even imagine it because they're so sensitive, and I'm certain they'd be miserable if they had to live outside away from their families. I can say, though, that if you leave any dog outside all the time and you don't make them a part of the family, you're pretty well guaranteed to create a mean dog.

        The bottom line is that whoever makes up these stupid lists of "aggressive dogs," which cause so much harm to the named dogs and their owners, should be put on the aggressive list themselves.

        A well-bred husky isn't supposed to be bad with people nor dogs. Generally, they're supposed to have an even temperament and are very friendly with people. They do have a pushier playing style at times, but it's uncharacteristic of the breed to be bad with dogs. The problem is, there are so many backyard breeders that produce huskies that act almost nothing like a well-bred husky that their reputation has been harmed over the years.

        I have an American pitbull terrier and he is the furthest thing from aggressive. He isn't fixed and he's never had any aggression towards anything or anyone. He's amazing with cats, kittens, puppies and children. He was recently attacked by 2 German Shepards. They snuck up on us and attacked with a pack mentality where one grabbed his back leg and the other had him by the neck. I had to fight them off him because he's so passive he wouldn't even defend himself. He's all stitched up now and will make a full recovery. I'm glad it happened to him and not his son (my 3month old puppy) because he would surely be dead.

        Pit bulls were not "designed" for dog fights. People made them do it. All of these dogs whom are mean it's because of the owners. Or if they were raised in a kennel or a pound. If people are kind and loving to the dog the dog will more than likely be kind and loving.

        A lot of people have problems with aggressive dogs at a very young age. The reason to this is that younger dogs play with eachother with nips. Most people mix up play time with aggression and thats what the problem is. If you look at your dog carefully and watch their emotion (look up how to read dog emotions) they might just be in a playful mood. This can be solved with a couple months of discipline or puppy training classes. Nipping can also mean they are bored or they want attention. Hope this helped! And please correct me if my facts are flat out wrong or I’m a little off if I am I apologize I’m just getting this evidence and information from my experience with having a dog.

        American Staffordshire Terrier and American Pit Bull Terrier are two very different dogs. Putting them in the same group is wrong on many levels. The American Staffordshire Terrier is more closely related to the Boxer. Both are a cross breed of the now extinct Bärenbeisser. A wild dog that was domesticated in Germany in the 1300s. Also known by the English name from the 1400s pet migration to England as Bullenbeisser. The Bärenbeisser was a big game hunter (hence the name is German for bear biter) and became extinct by crossbreeding rather than by a decadence of the breed.

        There may be a high percentage of fatalities associated with the pit bull, but you can’t ignore the fact that a high percentage of people raise these animals for purposes other than just having a loving pet.

        They are the most maligned because they are raised in an abusive way, and get the most bad press. You can cite the power of their jaws, and their over-all strength in destroying, killing or maiming, but those attributes only become a factor when associated with the viciousness instilled by an abusive owner.

        My English bulldog could chew your arm completely off, or crush every bone in your hand with the strength of his jaws if he was mistreated or trained in that way.

        Dogs are mean because people are mean. Every Pitt bull I’ve encountered, that was raised in a playful, loving home, was a playful, loving animal. Unless there is a brain anomaly, domestic canines are a product of nurture rather than nature.

        Just my opinion, of course.

        Personally, I think you are wrong because you haven't tested all of the dogs in the world. The dogs you put on the list are very misunderstood, and you can NOT blame the dog. It's 99.1% of the time 'human error'. (My guess). Most owners don't know how to train pit-bulls, or huskies, or shepherds. The Aussie is a nice dog. It's also a shepherd. Germans are not aggressive. It's mainly because of human error. Chow chows have a bad reputation but that doesn't mean it's dangerous. Have you done research on the web of these dogs?

        There is no debate about what the most dangerous dog breed is. Pit bulls have a disproportionate rate of serious injury and fatality. I know they can be great dogs, but they pose a risk far beyond their numbers.

        This is due to a combination of factors: they have tremendously powerful jaws, historically they were bred for aggression, and the wrong sort of people own them for the wrong sort of reason. Rotts, Chows, Huskies, Malumuts, Shepards, and Akitas contribute to a substantial number of serious injuries and fatal attacks on humans for similar reasons, but at much lower rates. Pit Bulls have higher injury severity scores than other dogs, as well as higher fatality rates. I.e. when a Pit Bull attacks, it is a much more serious injury than other dog breeds. Combined with the frequency of attacks, this adds up to real problems.

        A quarter to a third of all human deaths due to dog attacks are Pit Bulls, followed by Rotts (15%) and Shepherds (10%).

        This isn't a matter of "hate the breed", it is the reality of the situation. While all breeds can cause significant human injury, there is clearly a difference in the actual morbidity and mortality accounted for breed.

        Pit Bulls are the 57th most popular dog breed, but #1 in fatalities. Now Shepherds and Rotts are reasonably popular dogs (#2 and #9 per AKC), which contributes to the frequency of attacks (more dogs, more dog bites). However Labs (#1) and Goldens (#3), while they do bite, sometimes seriously, don't contribute anywhere near the morbidity and mortality.

        Dogs were bred for specific characteristics. It should not be surprising that fighting and guard dogs have higher inherent risk. This isn't just due to "bad breeding" and "bad owners" (which are both substantial contributors), but rather the intentional breeding over long periods of time. Nearly every Pit Bull I have met has been social and friendly. That doesn't mean the breed as a whole doesn't pose an inordinate risk.

        We need to adopt measures which educate people and work hard to put an end to dog fights and breeding Pit Bulls (and other breeds) to be particularly aggressive/vicious.

        I really hate when people hate the breed!! I think it is how you raise the dog! I was a shelter mom for a no kill shelter, loved it, but I do feel some of these pups came from inbreeding and that could lead to some problems! I rescued a 2 day old Australian Coolie or Koolie and his 2 brothers! They all were under 2 OZ. The 2 brothers passed within a week, heartbreaking, but we managed to save one Finn! Had his DNA done and he is half Cooli and half Golden retriever with a small amount of other breads! Finn is now 75 lbs. and very active. He is a sweet heart, but does jump and bark when he first meets people, but calms down soon! I had a Golden and he never did that! So I wonder if it could be some of his genes !

        Hi, Stephanie. I'm sorry you are having this trouble with the dog. As long as your husband continues to tease the dog, no one is going to be able to help. If he would stop the teasing, you might try feeding the dog yourself and try to show him that you are not going to take the food away. I am not a dog trainer, so I hesitate to give you any further advice. Good luck! :)

        My husband has a mixed breed dog about 50lb when we got married he was keeping him outside tied to the porch. Also I found out he teased the dog from the time it was little over it's food to try to get it to bite and snap at him. He thinks it's funny I guess. At first I tried to work with the dog some but most of my experience has been with raising a dog from a puppy not taking on a full grown dog and trying to reverse bad behavior and he had snapped at me several times and it made me nervous. This winter has been very cold so he has had to come in quite a bit and when my husband is gone he will not let me put him out to go to the bathroom even for up to twelve hours. Last time I tried to make him go outside because I had to run to the store he bit me. The dog is very nervous if he accidentally bumps into anything he cowers and hides forever. I am very frustrated over this situation (I've raised two different boxers that never offered to growl snap at or bite me over anything) All night tonight while my husband is out in a snow plow truck the dog has come to the bedroom door scratching on it then going to the front door wanting out. I get up to put him out and he runs and jumps on the sofa and won't go out. I need help!

        While I found this article interesting, much of your information was way off. For example, the Dalmatian dog breed was never a "rodent hunter". The Dalmatian is an ancient breed dating back to Roman times and was, and always has been, a carriage, (or even chariot) dog.

        The German Sheppard, although used as a Guard Dog during WW II, was originally bred to guard flocks of sheep and other live stock against the Timber Wolf.

        A writer should always write about what they know.

        I know about dogs. I have been training dogs and studying dogs for over 30 years. Your article includes "barking" as an aggressive behavior.

        Well, that is just silly. Most dogs will bark as a form of necessary communication and including barking as 'aggression' is a dangerous form of miss-information.

        I think you should write about a topic with which you are more familiar, instead of just regurgitating something you read.

        You are running the risk that your article will confuse people about their favorite dog breeds. And this could cause worthy dogs to go unwanted and un-adopted in shelters!

        I really question the validity of these results. Sample sizes as small as 46 are too small to have any confidence in the results. I think that you really should go back and either exclude any breeds where your sample size was less that a thousand or gather more data.

        I'm certain with a small enough sample sizes you could take the kindest and gentlest breed and make the top 5 most aggressive just because you happened to find 10 dogs on a bad day.

        Interesting article, and while I am a dog lover and don't generally like these types of lists, it pretty much supports my experiences. Regarding aggression, in my 55 years, I and or my dogs have been attacked 5 times. Once as a teen, I stepped into a yard where I had been before to deliver a paper and was bitten on the leg by a shepherd. In the last 5 years, while walking my leashed dogs through our neighborhood, my dogs have been attacked 3 times: once, during the day, we walked by a pick up truck and a husky flew off of it (I didn't even know it was there!) and first went after my small eskie, then when I grabbed her, she went after my big lab. As I was screaming a neighbor ran out to help at the same time as the contractor who owned the truck. He aplologized and said she had never done that before, the woman yelled at him that he was a liar. He went to pick up his husky and put it back in the truck, and she reached around andgrabbed his forearm! The second attack was by a chocolate lab who saw us from across a busy road. I stepped into the road to stop traffic thinking he was going to be hit...He bounced off of a truck that had slowed down to not hit him, then ran around the truck and went after my eskie, and then the lab. His owner ran across the street and said he had never done that...neighbors told me otherwise. The third time, we were walking on a sidewalk past a house and a Pomeranian bolted out of the back yard and started attacking, I wasn't afraid because he was so small. But then his pit mix sibling came running out and started to attack and in the fray knocked me over as well. The owner came running out and didn't even apologize, just shooed them into the back yard. As I was walking away, calling my husband to pick us up I was so shaken, I turned to see where we were on the street and she screamed her house number, " If I wanted to call the police", and I have to say, that was the straw that broke the camel's back, I called the police and they gave her a talking to. The last dog who attacked was a dalmation in my neighborhood who truly is a lunatic...aggressive toward people and animals. This is the family's second dalmation and the first was the same as this one! Is it their training or the breed? I had another friend with a dalmation who had to put her in a bedroom when anyone visited she was so untrustworthy. I was recently at a dog park where a lab and a pit were wrestling and playing very nicely and a boxer just came over and started fighting with the lab and the pit just backed away. I think we forget that dogs are animals! As much as we assign human qualities and emotions to them, they're still animals and sometimes something just isn't right with them. Not unlike some of the aggressive humans in our world.

        Having owned German Shepherds, Doberman Pinschers, and currently owning a German Rottweiler and a Rottweiler/Rhodesian Ridgeback, I can say it is all in how they are brought up as to there aggressiveness.

        Will have to disagree on Rottweilers having short hair though. Mine has long hair even though he is nearing 4 years old. His AKC parents were in the 135 to 155lb size but he was the runt of the litter and weighs in at about 95 lbs. He is very area protective and owner protective. Don't come near his pen, Petmate, or pickup truck unless bearing food if he does not know you and like you. Now to both myself and mom, he will come up and want a hug, petting or even to be a lap dog. He was never trained that way but just is the way he is.

        The R/RR looks like the Rhodesian Ridgeback in color but has the body of the Rottweiler. Don't try to out run that dog. And at 110 lbs, can hurt you if he runs into you at full speed. Only to try to lick you to death.

        Now why aren't Poodles on the list? I've even walked right by German Shepherds that owners say hate everyone but a Poodle is the only one that has bit. Chihuahuas suffer from big dog syndrome in most cases. Most of them turn friendly if given a chance to get on your lap.

        Any breed of dog can and will be aggressive if not raised/trained properly or are undertrained. You also must establish dominence over your dog since they are pack animals. If you don't they will own you and they will put you or other family members in their place which can and will include biting, attacking, fighting, etc. I have owned 3 pit bulls a black lab, and a coonhound. Currently I have a pitbull and my put bulls have been the biggest love bugs. All of my animals I have ever owned have been sweet and non-aggressive even if attacked by another dog. This is a load of bs and landlords, management companies, and insurance companies shouldn't be allowed to be "breedist" or against any breed, they should be meeting the animals first to see how they behave, etc.

        I rescued a yorkie. He seemed fine for about a week, then while playing, became very aggressive and bit me. I asked the rescue agency about this, they said he had trust issues. I took him to a trainer, read articles, and worked with my vet. He seemed to respond until 7 months later, I was wiping him off after rain, and he again became aggressive and bit again. Both these incidents were not things we had done before. He is 3 years old. Other wise he is very well behaved, house broken, doesn't get into anything, and is very loving. I don't understand what brings on this aggression. Any ideas?

        I really liked your article, it's got a meaningful opening statement, detailed body of work and a conclusion with sources. I have to completely agree with the little napoleons. Lucky for me all dogs tend to like me. Well, maybe with the exception of that one Shih Tzu... that had to be the noisiest dog I have ever known.

        I could add other dogs that I feel are much more intimidating than those you have listed. However, they are not as common as those you described. Honestly, It would be difficult to counter your conclusions with the supporting documentation. Hey, I'm impressed.

        I have a 4 year old Pit Bull, I got her at 5 week's old. She has been like a baby she is so loving she loves to cuddle up on the sofa with me. The only time I ever see her get upset was when she see a mother slap her son and the boy cried. So many don't know the back ground of the Pit Bull they just hear horror stories and judge by that. But the Pit Bull was called the Nanny dog due to the way are are with children. The way I see it all is that due to a handful of people that have had Pit's and made them fight make all the other's look bad. It upsets me when I hear or see people saying Pits are bad. EVERY dog has the means of being aggressive the same as any human has that liability. I have been around dogs all my life as my father was a dog trainer it was not unusual to have seen 70 plus dog's in our kennels at one time.

        I have always thought of Chihuahuas to be aggressive, since they are small.

        I raised chowchows for 20 yrs. This is a bunch of bunk. Any dog will be aggressive if not trained properly. I had 7 at one time that were around all of my children and grandchildren. they used them for pillows most of the time. In all that time, none of mine ever showed any signs of aggression toward anyone except a stranger who walked in my yard uninvited and the children were outside. What idiot(s) does this testing?

        Who is training these Pits that are killing humans each year to be aggressive? The owners? Hog wash. You read all the time where the gentle family pit goes off and kills the owner or one of the kids or a family member. Are you saying these Pit owners who lose a child or a family member are training their Pits to be more aggressive? lol I have to laugh at that logic. It is baseless. The breed itself is aggressive by nature without anyone needing to train them to be even more aggressive, and that is the common problem with Pit Bulls as a breed.

        In fact in most of these stories about pit bulls killing a human being, we never hear reports of the owners being abusive to the dogs or that the dogs were mistreated by the owners. Why is that? No the pit bull apologists just always chalk up a pit bull death to bad ownership when that logic is baseless and not proven.

        The fact that there are far more bad lab owners than pit owners and far more abused labs in the US than Pits, yet labs account for only a fraction of human deaths each year compared to Pits should tell you something. If it is the owner and not the dog then again, there should be far more human deaths from Labs than from pits. But again, the tangible statistics do not back this up.

        I wonder why?

        I appreciate your opinion, I will just say this, many of that 6% have been trained to be aggressive. How many labs do you know that were trained to be aggressive? This makes a huge difference in the numbers.

        Your comments on here are borderline irresponsible regarding pit bulls with regards to being "good and patient with children". It is all pit defenders need in order to "justify" owning one of them or purchasing one.

        Pits are responsible for 71% of the human deaths in the US each year yet are only 6% of the dog ownership populous.

        Now to address the "pit defenders" on here that say it is a bad owner and not the dog. Labs are the most popular and most owned dog breed in the US, so if the "pit defenders" logic about being bad owners and not a breed is correct. Then there should be way more fatalities each year from Labs then pits. There are surely a lot more bad owners of Labs than pits simply because of how high the ownership is.

        Yet labs kill humans at a much lower rate despite being the most owned dog compared to Pits at only 6%.

        So please Pit defenders explain to me how this math works out? Explain how only 6% of the dog ownership that is responsible for 71% of human deaths is about the owner and not the breed? Explain how there are way more bad lab owners out there, but yet labs rarely kill humans?

        I will be waiting for an answer. Probably wont get one though. Pit owners gonna get pits.

        I find all of the jack rusself I have met to be extreamly good with children, I have a jack Russel myself, she's great with children too! A bit iffy with other dogs but that stems from a bad experience with another dog so we are trying to socialise her more so she becomes comfortable again and not intimidated to the point of being aggressively defensive. But yea, brilliant with children but temperamental with other dogs

        As s vetvtech for 15 years , I have handled every breed there is many times. I love all dogs and have no predjudive against certain breeds . Here is my list of the most consistantly aggressive dog breeds I've experienced over and over in no certain order. German shepherds, Rottweilers, chows, chihuahuas,jacknrussells,mini pins,. Nope, not one pit bull even though a large percent of our clients had pits. On a so so level, golden retrievers, English bulldogs. This is not to breed bash, it's just what I've experienced over 15 years.

        No dog is just extremely aggressive. They have to be trained or beaten to become aggressive. A "dangerous" dog can be a great pet. There for a dog that has been trained to become aggressive does not care whether it attacks a kid adult elder wild or tame animal. That is why a lot of them have that reputation.

        Not a very scientific study and I don't understand having different samplings of each breed. I do however, agree that the smaller dogs like dachshunds and chihuahuas are more aggressive than larger breeds

        This is a very misleading article. These are not the most aggressive breeds according to the one source that is sited.

        "The percentage of the test results I have included are from the American Temperament Test Society."

        While the test results in the link are from April of 2016, they certainly don't represent the claims of this article.

        I do agree however that the tests were not fair in that some breeds only had 1 or 2 tested. Not good science.

        I agree with many of you saying that pitbulls are not aggressive.

        Another article that also uses the ATTS for it's information really puts the pitbull test results on display here:

        Husky's are not known to be aggressive with humans. They are very friendly and social dogs. However, they were bred to hunt small animals. Instinct will kick in. They are not good with small pets, and be very careful with them around tiny infants. They may not distinguish between a baby and a small critter.

        Also the comment in the article about not believing that German Shepherds are aggressive can be misleading. In the past,we have owned 2 German Shepherds. They do not actively seek out confrontation, but they will defend their territory quite violently to any real or perceived danger.

        My sister ,Dorothy, 74 has a chihuahua that definitely has "Little Dog Syndrome " but I have two toy rat terriers with the same syndrome. They chase any dog, barking and running after regardless of size. Our neighbor, Ed had a Rhodesian Ridgeback. That would just stand there when our Rex bit her on the ankles. Growling and biting all-the-while, never made a defensive movement. Rex still chases any four legged animal that is twice as tall as him."Small Dog Syndrome is appealing to very small dogs. Must be aggressive, bite first, the bigger the target the greater the challenge, the greater the victory when you have ."scared him off"

        This is a very good article. I hate how soften many people here in the comments still insist that pitbulls are the most aggressive dogs. The fact is that they are not. They simply have a high fatality rate because they were bread to not let go where as most breeds bite repeatedly and can be removed. You have to understand they were bread and trained for centuries to literally drag Bulls to the ground (bull baiting). All dogs bite. Some more than others. But pitbulls are not one of those others. They just have a more dangerous bite when they do. Also the only thing in the article I didn't like we're the inconsistent sample sizes.

        Siberian Huskies are not really aggressive if well socialized. I have shared my life with 3 of them. Two we had since puppyhood (one was 8 weeks, the other 6 months when we got her), and the other was found roaming the streets by the police who gave her to us instead of to the pound when no one claimed her. The two we raised and socialized, Maggie and Katie were Canine Good Citizens. Both were great with kids. Katie, the one we had since 8 weeks was a Nanna Dog to my son. She was so intuitive with our epileptic Boston, she almost became an epilepsy therapy dog. Margie, the dog found running the streets seemed friendly but was aggressive. She bit people when they came on our property and we could not find anyone who would take her. She never bit my child, but she would growl at him as a warning. She attacked Katie whenever she had the chance. When we got her she was still lactating from having puppies. We advertised but could not find her owner. We tried to rehome her but the only people who wanted her, wanted to breed her. One guy sounded good until he called from the racetrack. Some people use Huskies as bait in dog fights as they will fight to the death. I think Margie was used by a backyard breeder. She was beautiful and friendly but was not used to being indoors and was half wild. She was not housebroken and hid under furniture and lurked in the shadows of a room. I did some research a few years ago, and almost all the Siberian Huskies that killed people in the last 25 or so years have been kept outside and tied on or left to run with other Siberian Huskies in a pack situation. There was a Siberian Husky in a city near us that killed a child on Thanksgiving day in 1996. The dog was kept tied on in the backyard along with a Chow Chow, which is known to be an aggressive dog. The child had been told not to go near the dogs, but it was Thanksgiving and adults were not attending to him. Witnesses say that the Chow Chow attacked first, and probably killed him, but the Husky kept it up. Huskies are beautiful because they look wild. There is still a lot of the wild in them. Even the best trained Huskies have some degree of wanderlust. When they are not kept indoors with people, especially when they are tied on outside or left to roam on a large acre property with a pack, they become wild. They are not aggressive, but they have been involved in a number of fatal dog attacks. If you study this list, the vast majority of fatal attacks involving a Husky was "Chained Dog." There was also an incident in Canada where the Husky was left to run with a pack. http://americaagainstbsl.tripod.com/fatal_dog_atta...

        Interest list of dog breeds. I was surprised to see dalmatians on here, but then I am not familiar with any of that breed. Not surprised by the rest listed. I would much rather have a large dog breed, and a German Shepard it at the top for me. Having had a few, I know they can be protective and I like that. Aggressive and stupid for now reason, no way.

        Hi All

        Unfortunately your list is confused. You report the percent as percent failed when it meets your a priori assumption about specific breeds, and present those same data as percent passed when when convenient. German Shepherds for example "PASSED" 84% of the time. This is very high as the highest rated breed listed was Labrador retrievers at ~90% (http://atts.org/breed-statistics). But dont just take my word for it, use the link!

        It is critical we use these data appropriately as this can lead to misinformation.

        To address the concern about deaths caused by particular breeds, one can not simply look at the number of deaths as it does not take into account the actual number of animals in the system (ie how many German shepherds are there vs Rottweilers). In addition, one could also ask if there is bias in reporting attacks. There is good reason to believe that folks attacked by pitbulls report attacks more often then attacks by Chihuahuas because of the severity of the injuries. Powerful breeds can muster powerful attacks.

        Train all dogs well and expect happy mentors (you...) and neighbors!

        Cheers

        Damon

        The list is great I even liked how you mentioned Pit Bulls are great with little kids. They are very sweet loving dogs but that is a double edged sword. I had a Chow who was the smartest dog I have ever seen. Realistically they are so smart they don't see why pleasing their owners is that big a deal. Like he would take a few pats on the head so you could feel good then walk a step away. He still loved us as completely as any family member could, he was just independent, and content with himself internally. One old guy next door had fed him egg yokes every morning for several years before he thought he could pat on Bears head. He nipped his hand without hesitation. The ratio of width/depth/height of his mouth and the heaviness of his back molars is nothing like any dog I have seen. Plus his natural obsession with patrolling and watching every door and window for intruders was his all encompassing passion. He would get out sometimes once in particular a huge yellow lab made the slightest little grr as he was walking near him(away from me of course). And without the slightest warning he had flipped the dog like a world champion Judo master. He started the lunge impossibly low and then exploded with power into the throat of the Big lab driving him up enough to then perform the complete head over heals flip. It was quick and I honestly could barley see how it happened, but I was close enough and adrenaline surged enough to lift bear off the dog. The lab was on his back with all four legs pointing straight up and bear was on his chest with the dogs throat in his mouth. I do love this breed but it can seriously hurt someone or someones pet.
