The most aggressive dog breed. Aggressive breeds. place - Cuties with a "bad temper"

It is not so easy to make an adequate TOP-10 of the most aggressive dogs. A number of questions immediately arise, for example, who exactly do the representatives of the breed dislike? Are their relatives or are they still inclined to show in relation to a person?

Is it correct to include in the rating of the most aggressive four-legged dogs that were bred for and protection? What metrics to rely on? For example, if we take the statistics of human bites as a basis, it varies greatly according to the territorial principle. Let's try to be objective. Statistics is a fundamental science, but it always has an error. When compiling a table with the number of bites, no one takes into account the lifestyle of the "culprit", his mental state and motives, only the fact is taken into account.

Digging deeper, is it right to hang labels? Is it adequate to make a rating based on personal experience and the attachments of a group of people? But what about killer dogs living in families with children and acting as nannies? What about the pit bull that wandered through the woods until it found its 6-year-old owner? Is it possible to overlook the young, burned Rottweiler, who carried two small children out of a burning house and returned for their mother? So, the TOP-10 will be given below, but not breeds, but their groups that show aggression for various reasons.

Let's start the list of the most aggressive dogs with those breeds that are not able to cause serious damage, but if they are a little larger. Miniature dogs are not only prone to aggression, their rage is indescribable. The best defense is an attack, and if a dog is used to walking in a bag and never got the freedom to solve his own problems, he turns into a sociopath. Unfortunately, many owners do not take into account the natural needs of their 3-kilogram "predators", which results in mental disorders, grumpiness and a passive-defensive reaction towards animals and people. The crumbs that will "make you shiver" are:

  • Papillon.

9th place - Breeds prone to bites in a state of excitement

Oddly enough, the best burrow hunters turned out to be here - Dachshund and. Both breeds tend to fall into the hunting game. Physically, the dog is experiencing overload, the eyes are covered with a veil, and heartbeats are heard in the ears. Such a state can be provoked by instincts or deliberate provocation on the part of a person. Even when biting, the quadruped is not fully aware of its actions, which is why self-control is so important for burrow hunters.

8th place - Cuties with a "bad temper"

Breeds that have nothing to justify ... they bite when they feel like it. Often, quadrupeds show their teeth to the owner, for example, if they are forced to do something. Cuties to be careful with are:


- A companion and protector bred in China, a shaggy lion, which may be a relative of the Tibetan Mastiff. Quadrupeds bite, defending their opinion and do not see anything supernatural in this action.


American Cocker Spaniel- a dog-mat, almost the Barbie of the four-legged world and suddenly aggression. It must be said that it is not easy to provoke a spaniel to bite. Quadrupeds can go to extremes, frightened or confused. The danger in the biting technique is that the dog is intercepted rather than held, inflicting many deep wounds in a short time.

7th place - Breeds prone to mental instability

- even at the dawn of the breeding of the breed, cynologists characterized it as difficult to control. Four-legged excellent guards, protection of the territory is their meaning of life, but with a lack of attention, education or chain (enclosure) maintenance, the Moscow watchdogs literally go berserk. Such a breed should not be started for fuzzy purposes - only protection!


The Moscow watchdog cannot be an “experiment”, and the owner must have a solid experience in raising dogs. By the way, the lists in which the most aggressive breeds are given are often made - good-natured companions, similar to the Moscow watchdog in appearance. Perhaps this is a “consequence of statistics”, in which the guilty quadrupeds, similar to the St. Bernards, are included.


(BRT) - the story is almost the same as with the Moscow watchdog. The breed is factory and "unfinished". BRTs are also prone to mental instability if they are not properly raised or maintained. Surely, the gigantic size played an important role in getting the breed into this rating. By the way, the BRT also has a "double" - which is often and unfairly ranked as an aggressor.

6th place - Aggressive to relatives

Purebred fighting dogs do not harbor malice towards people - this is a fact. However, these breeds are aggressive towards other dogs and in the heat of a fight, anything can happen. In addition, "breeders" who sell semi-pedigreed puppies under the guise of thoroughbreds are more guilty of bloody consequences than the four-legged ones themselves. Killer dogs according to the media are:

  • Pit bull terrier.
  • Bull Terrier.

5th place - Breeds requiring disciplinary control

And Dogo Canario- two very serious breeds that should not fall into inexperienced hands. The mental health of the four-legged directly depends on the behavior and "position" of the owner.


The owner of the dog must be the leader of the pack in sickness and in health, and if this rule is violated, there will be trouble.


For unknown reasons, and gets into the rating of aggressors. Probably, the reputation of the breed is "tarnished" by its brethren and people's fear of the size of four-legged animals. If we are talking about big and really angry dogs, then it is more logical to call the Pakistani Mastiff or the Brindis Fighting Dog. However, the breeds are so rare that statistics bypass them.

4th place - Ancient breeds that carried natural aggression through the ages

- a very fashionable breed, which is called aggressive. In fact, Malamutes are specific, require loads, but do not suffer from fits of anger. But Alaskan Husky is a half-wolf, created and tamed by the peoples of the north. Unlike (registered), Alaskan dogs are not recognized and considered a group, that is, they do not have a clear standard and characteristics. The same can be said about the rare Sakhalin Huskies, it is known that they are hardy and resistant, but it is difficult to say how tolerant of others.

3rd place - Hybrids

Man is a rather strange creature, it is always not enough for him what he has. Out of curiosity, and maybe boredom, the human brain generates pretty crazy ideas, which include the creation of hybrids. It must be understood that a hybrid is a descendant of two individuals belonging to different species, and a mestizo is a mixture of a purebred and outbred animal. The most famous, desirable and at the same time dangerous hybrid is a cross between a wolf and a dog.(in factory work - German Shepherd).

During the Upper Paleolithic, which dominated the planet 40,000-12,000 years ago, people domesticated the wolf. As a result, a person acquired not only a hunting assistant and a vigilant watchman, but also a friend who demonstrates love for the owner, devotion and high intelligence.

Thanks to the painstaking work of breeders, today there are hundreds of breeds in the world. Among them, cynologists pay special attention to the most aggressive dogs - a group of animals that have inherited from their wild ancestor a vicious disposition and predatory instincts.

Sixth place - dachshund


Who would have thought that a small dog with a disproportionately elongated body, whose height at the withers barely reaches 25 cm, can show aggressive character traits? However, looks are deceiving. A funny short-legged creature with expressive eyes deservedly takes 5th place in the ranking of the most aggressive dogs. According to research by zoologists at the University of Pennsylvania, representatives of the breed are prone to unpredictability and uncontrollable outbursts of rage. Scientists have found that every 12th dachshund has bitten its owner at least once in its life.

The aggressiveness of dachshunds is explained by the belonging of these animals to hunting burrowing breeds. In order to overcome an obstinate badger or an angry fox, a four-legged fisherman must have cunning, perseverance and anger. That's why do not start a dachshund as a sofa dog- inept upbringing will turn a charming eared puppy into a stubborn wayward creature. Such pets snap at any touch that they find unpleasant.

Fifth place - Alaskan Malamute


Inseparable companions of the natives of the coast of Alaska, these powerful dogs with a height of 59–63 cm and a weight of 37–40 kg resemble large wolves. For centuries, the Eskimos and Indians have used Malamutes as sled dogs, capable of tirelessly pulling laden sleds. In addition, the animals carried out guard duty, driving away bears and wolves from the villages. The harsh living conditions left their mark on the character of the dogs. Representatives of the breed have a masterful disposition and lack of unquestioning obedience.

Malamute aggression is manifested in relation to other dogs, especially to individuals of the same sex. This is due to the inherent dominance of the breed. Under natural conditions, everyone tries to get the title of leader, entering into a fight with fellow tribesmen for an honorary title. Today, problems with the manifestation of uncontrolled viciousness appear due to the owners' lack of ideas about the proper upbringing of a pet. The owner of these majestic children of the North needs to know that the most important element in training a four-legged friend is discipline and early socialization.

Fourth place - Dogo Argentino


The progenitors of modern white dogs are proud mastiffs brought to Argentine lands in the 16th century. Their appearance was the beginning of the popularity of dog fighting in the country. Infinitely courageous and hardy creatures led Professor Antonio Martinez to the idea of ​​​​creating dogs that absorbed the best features of the strong Molossians. A new breed was finally formed only in the XX century. Its representatives exceeded all expectations - muscular four-legged athletes 61–68 cm high at the withers not only successfully participated in the persecution of wild animals, but also showed excellent results as security guards.

Currently, the import and maintenance of Dogo Argentino is prohibited in Norway, Israel, Great Britain, Portugal, New Zealand and Spain. For a person who dares to acquire a fearless dog as a pet, it is important to know that violence is prohibited during training. Cruel punishments (shouting, beating) will destroy mutual understanding between the owner and the pet and provoke hatred and uncontrollability of the animal.

Third place - chow-chow


In the III century BC. e. in the Chinese chronicles there were already records of unusual dogs with thick hair, the body of a bear and the head of a lion. Cute creatures that charmed the local nobility with their exotic appearance and unique blue tongue arrived in Europe in 1785. The exterior standard (height at the withers - 46-56 cm, body weight - 20-32 kg) was developed in 1895. At the same time, Chow Chow was officially recognized as an independent breed.

Melancholy dogs behave with restraint, not showing affection and tender feelings to the owner. To strangers who want to stroke a pretty furry creature, the dog growls to understand that this is not worth doing. Chow Chows are also not friendly to other pets. Provoked to fight, they fight to the end. Gross mistakes in training lead to the transformation of cozy "teddy bears" into vicious aggressors. These dogs should not be trained as service dogs.. Having acquired guard skills, they begin to protect the owner even from imaginary enemies.

Second place - Doberman


In the second half of the 19th century, the court clerk Friedrich Louis Dobermann from the German city of Apolda set out to create a dog with vigilance, ferocity, fearlessness and intelligence. The result of his work were dogs, the main character trait of which was activity and viciousness. Their height at the withers reached 72 cm, and the mass of a muscular toned body was 45 kg. So that families with children could also afford the maintenance of representatives of the breed, Dobermann's follower, Otto Geller, softened the evil temper of the animal.

The aggressiveness of the Doberman is the result of an explosive temperament. These powerful dogs are devoted to the owner and are ready to protect him at the slightest manifestation of hostility. Unfortunately, dog handlers have recently faced another problem. In pursuit of a magnificent exterior, breeders often cross relative dogs. This leads to the birth of puppies with a deliberately inadequate psyche, characterized by cowardice, aggression or excessive excitability.

The most aggressive dog breed in the world

The American Staffordshire Terrier is the most aggressive dog breed in the world.. The history of the breed goes back to the Middle Ages, when fights involving dogs came into fashion. People artificially bred dogs capable of fighting not only with their own kind, but also with angry bulls. The forefathers of modern American Staffordshires were powerful hardy bulldogs and temperamental mobile terriers. According to the breed standard approved in 1971, the Amstaff is a dog with a powerful physique, compact body, developed chest, strong legs and a broad head. Height at the withers - 44-48 cm, weight - 25-30 kg.

American Staffordshire - dogs with a controversial character. They can be both affectionate family pets and fearless fighters. Improperly brought up death grip owners are a potential threat to society. The only way to control a pet is a firm hand and proper training, based on the absence of cruelty and rudeness. Unfair punishments will lead to aggression and uncontrollable behavior in the dog.

According to statistics, the Dachshund, the Alaskan Malamute, the Argentinean Great Dane, the Chow Chow, the Doberman and the American Staffordshire Terrier are considered to be the most aggressive dogs. However, breeders claim that only 17.8% of these breeds have behavioral problems. According to cynologists, dogs that did not undergo a course of training or were subjected to mistreatment showed a vicious disposition.

Any dog ​​can bite. But some dogs do this much more often than other breeds. We tend to mistakenly believe that the most biting and aggressive are large and dangerous dog breeds such as Pit Bull Terriers, Rottweilers and Dobermans. It will come as a surprise to many, but more often than not, smaller breeds of dogs are more aggressive than truly dangerous.

Below we present the TOP 10 most aggressive breeds:



In second place in the ranking is an even smaller breed of dog - the Chihuahua. Recently, dogs of this breed have become very fashionable, many do not take them seriously. But in vain! When a Chihuahua is aggressive, not many dogs will outdo it. You are more likely to be bitten by a Chihuahua than a Rottweiler.

The leadership qualities of this breed are very developed, so the owners must properly educate their pets, socialize the Chihuahua in the company of other dogs from early childhood.




The third most aggressive dog breed in the world was not a pit bull or a Doberman, but another "toy" dog - Jack Russell Terrier. Terriers of all sizes do not tolerate rough handling and will be fiercely defensive. Therefore, it is necessary to ensure that children do not offend the dog.

Most often, Jack Russell Terriers show their aggression with other dogs. To make them calmer, a dog needs a lot of exercise, running and training.




The Pekingese cannot threaten people due to its small size, but this breed can be very jealous and aggressive. It is mainly directed at other dogs or strangers coming to visit.

It is quite difficult to re-educate a Pekingese. They are stubborn, and, as a rule, they choose only one person for themselves, with whom they are ready to get close and make friends. To the rest of the Pekingese are very wary and aggressive. They also do not get along well with small children.




Shar Pei are Chinese dogs listed in the Guinness Book of Records as one of the rarest breeds in the world. Dogs of this breed have a very independent and dominant character, they like to be the main ones in the family, so from childhood they should be explained who is the boss in the house.

In China, Shar-Peis have successfully taken part in battles, so their genes show aggression towards other dogs. In families, dogs of this breed live well, but do not always show patience with children. Early socialization of the dog can help keep aggression to a minimum.




Some will be surprised to see a Chow Chow in this ranking, but nevertheless, this breed is one of the most aggressive dogs in the world. At first glance, Chow Chows are very attractive and cute fluffies, also representatives of China. Before getting this dog, it must be remembered that adult Chow Chows should not be quietly allowed to play with unfamiliar dogs and left alone with children, because they are very irritable and defend the right to their food with an evil grin.

Chow-chows are also good guards, they are very devoted to their master and will not let a stranger to him and will not let anyone into their territory.

The Shiba Inu is a very ancient Japanese breed used for hunting in the highlands. The dog is very loyal, but at the same time showing that it can live without an owner. Early socialization helps this breed get used to people.

Shiba Inu does not get along well with other dogs, they are very aggressive towards them. In case of danger and aggression, the Shiba makes a strange sound, similar to screaming and howling. With such a dog, you need to constantly engage in, give it various physical activities.




Stylish and decorative Papillon bites very strongly. Most often, his aggression is directed at children, who quickly begin to annoy the dog, and can be bitten.

Papillons are great owners, and out of jealousy for the owner, they can fearlessly rush at a stranger. Therefore, although this dog is small, it is very aggressive. Early socialization of puppies will help to avoid deviations in behavior, as well as prevent aggression.

Shih Tzu is a dog from China, which means “lion dog” in translation, because it resembles the Chinese image of a lion. They are fearless, intelligent and temperamental dogs, but like any predator, they need to curb their temperament so that the Shih Tzu does not take on the role of a wayward leader.

Aggression can be caused by negligence towards this breed, resentment from a previous owner, or lack of communication. The dog can cling to the legs, bite and pounce on any objects, including people and children. Shih Tzu needs to be brought up correctly from childhood so that she does not show her aggressiveness.
