The danger of representatives of this breed lies in a sudden attack on the enemy, and dogs often mistake an imaginary threat for a real one.

There are pros and cons to any dog ​​breed when choosing to purchase a puppy. But large ones vicious dogs require responsible upbringing. They are not suitable as a pet for children, people with weak character or unstable psyche.

Selection criteria

Every reader understands that any dog ​​can show aggression and attack a person. This does not depend on the breed or size of the animal, but on certain circumstances. A lapdog or Yorkshire terrier will growl and even bite if you take away a treat from him.

What then can we say about Rottweilers, who have highly developed guard qualities?

What criteria are used to determine the viciousness of dogs? Scientists have included in the list of aggressors representatives of those breeds that, according to observations, are most prone to unexpected and violent attacks, demonstrating destructive behavior, showing unmotivated asociality.

Unexpected facts

Chow chows and dachshunds are considered good-natured animals that are safe to keep. Indeed, they are calm and balanced, but there are cases where a chow-chow attacked its owner only because he forgot to feed it, and a dachshund crippled a 33-year-old man, taking revenge for shouting.

In general, according to the University of Pennsylvania, dachshunds are the most aggressive dogs! Such conclusions were made on the basis of statistics according to which every 12th dachshund attacks not only strangers.

It is quite clear that this depends not only on the size of the animal or the strength of its jaws, but also on the determination of the dog, as well as the fighting qualities of a representative of a particular breed. The totality of these and other indicators can be summed up in one word - ferocity.

This dog is perhaps the strongest in the world - the weight of individual individuals (males) reaches 90 kg, and its jaws can easily bite tibia large ungulates. There is a known case when in Karelia a Caucasian Shepherd dog single-handedly killed a pack of wolves that had previously terrorized a remote village. The dog got loose at night and ran off for a walk, and in the morning his owner found the “Caucasian” surrounded by scraps of fur and bones of gray predators. In his teeth he squeezed the neck of a seasoned she-wolf, who, apparently, lived longer than the rest. Today it has been reliably established that the ancestor of the Caucasian Shepherd is the Tibetan Great Dane, which in turn descended from large wolves. However, looking at these huge dogs, you involuntarily begin to think that the true ancestor of the “Caucasians” is, after all, a bear. The Caucasian Shepherd belongs to the category of companion dogs, and not aggressive fighters or hunters. She has a fairly good-natured disposition and will never rush at a person first, unless it is a specially trained animal. Therefore, despite its impressive strength, the “Caucasian” only rounds out the top five most ferocious dogs in the world.

4. Boxer

In 4th place in our ranking is the boxer - hunting and guard dog. It is distinguished by its fearlessness and powerful jaws, which inflict terrible injuries on its prey. Modern boxers are descended from the Dutch breed "Bullenbeiser", which translates as "bull biter". In Rus', where the breed was popular among nobles, these dogs were called “bulldogs.” And after crossing them with English bulldogs, very successful dogs appeared - boxers. The dogs received this name because of their unusual habit of fighting not only with their teeth, but also with their front paws. One of the main characteristics of the breed is its pincer bite. It allows the boxer, who has grabbed the victim, to literally hang on him. Cases have been recorded when it was not possible to tear a dog away from a hated enemy even after the death of the dog. Death grip inherited from the bulldog and square shape muzzle allows boxers to rip pieces of meat from their enemies, and then simply wait for them to bleed to death. It is no coincidence that Boxers are called sports dogs for their will to win and the highest fighting qualities.

The third place in our top is taken by the Rottweiler. This is a very serious dog, classified as a guard dog, but it is also one of the strongest fighting dogs in the world. The ancestor of the Rottweiler is the black Swiss sheep, and the breed received its name thanks to the German city of Rot Weil, where it finally took shape. Most Rottweilers are friendly and behave calmly even with strangers. However, it is in this breed that, although rarely, uncontrollable outbursts of rage are noted and in this case the Rottweiler deals with the victim with lightning speed. For example, not so long ago, near Chelyabinsk, a Rottweiler killed an eight-year-old child, instantly biting his neck. The dog was shot, and the motives for such behavior are not fully understood. They may be related to the white spots in the breed's origins. According to one hypothesis, in the old days Rottweilers were trained to guard black slaves, and some dogs perceive certain gestures as an attempt to escape, which prompts them to aggression. Due to their strength and agility, Rottweilers are actively used in dog fights. It is believed that, other things being equal (weight, height, level of training), these dogs have preferable chances in confrontation with Alabais and Dobermans. But in a fight between a Rottweiler and a pit bull, the chances of winning are approximately the same.

The bull terriers we put in second place were bred in the mid-19th century in England by breeder James Hincks. His goal was to create an ideal fighting breed, since it was at this time that bullfighting was banned in Britain, entertainment for the people and ordinary people switched to rat-baiting shows and dog fights. The breeder achieved a brilliant result by crossing a bulldog, a terrier and a Dalmatian, resulting in a muscular dog with a characteristic elongated muzzle. The Bull Terrier is distinguished by its insane courage, death grip, agility, immunity to pain and, oddly enough... intelligence. Yes, yes, contrary to the stereotype, the bull terrier does not rush at everything that moves, but treats the owner and members of his pack (that is, family) with reverence and tenderness. The idea of ​​the irrepressible aggressiveness of the bull terrier arose because of his attitude towards other dogs. Indeed, being a born fighter, he instinctively perceives dogs (especially males) as enemies and competitors with whom he must definitely fight. In such fights, this rat-like baby is able to defeat even much larger individuals, so it legitimately takes second place in the ranking of the most ferocious dogs.

But we put pit bull terriers or, in common parlance, pit bulls, in the honorable first place. These dogs have a bad reputation because there are many cases where they killed people. Not long ago in Nizhnevartovsk a pit bull gnawed its throat to his own master, and it all started with fun game which turned into a tragedy. This breed is so dangerous that it is prohibited for keeping and breeding in many countries of the world, including Soviet Union. Pit bull terriers were bred on the basis English bulldogs about three hundred years ago. It was supposed to be a strong and aggressive guard dog, but the breed turned out to be so ferocious that pit bulls were subsequently actively used in dog fighting. As practice has shown, only a few dogs can resist them in the arena or in a street fight. There are some chances against a pit bull, except for representatives of the above-described breeds from this rating. And even then, before the Caucasian Shepherd gets angry, in order to truly aggressively confront the pit bull, he will have time to tear out her Adam’s apple, which often happens during dog fights. The Pitbull is a born fighter, ready to fight at any time of the day or night. Despite their increased aggressiveness, these dogs are actively used by the military, customs officers and even special services. Without a doubt, this is not only the most ferocious, but also one of the most intelligent dogs peace. Pit bulls have a well-deserved reputation as ruthless killers, so you should stay away from them and think ten times before getting such a dog at home.

As the famous song says, “A dog only bites because of a dog’s life...”. As a rule, the character of a dog depends on the upbringing and attitude of the owner towards it, but there are breeds of dogs that have fighting qualities “in their blood”. These dogs must be handled with the most care, with great patience, without allowing yourself to raise your voice when training, or, worse, hit the dog. The most dangerous dog breeds include the Staffordshire Terrier, Doberman Pinscher, Pit Bull, Rottweiler, Bull Terrier, German Boxer, German shepherd, Pakistani Mastiff, Chihuahua, Chow Chow.

A dog of this breed - born guard, the protector of the home, therefore treats guests with distrust, demonstrating his dissatisfaction with a growl. The dog recognizes only members of its family, allowing them to caress and stroke it. Under no circumstances should strangers do this! The Staffordshire Terrier can mistake a friendly gesture from a stranger for aggression and use its sharp fangs. A dog of this breed is not only an excellent guard, but also a tireless fighter who will fight until victory. The dog's favorite technique is to grab his opponent by the throat, gradually squeezing his jaws.
The Staffordshire Terrier needs an owner who is decisive and confident in his abilities, who will keep the dog “on a short leash.” Otherwise, this dog will feel like the master of the situation and will dictate its terms to people.

Like a dog guard breed, the Doberman is characterized by such character traits as fearlessness, self-confidence, instant reaction to any sound, insight, keen hearing, keen sense And high speed running. At the same time, a Doberman (especially a female) can be impulsive, intolerant of others - both people and animals, and sometimes show discontent and aggression.

Many people believe that the Doberman Pinscher is a very aggressive and vicious dog by nature. But that's not true. The Doberman is very attached to its owners, and with all its might it demonstrates its love and tenderness to them. But as soon as the dog feels a threat to its owners (for example, a conversation with a neighbor in high notes), it is immediately ready to defend itself. Therefore, you only need to walk your dog on a leash and always wear a muzzle. But since the dog of this breed is unusually smart, it does not rush into battle immediately, but first assesses the situation.

American Pit Bull Terrier

This dog has long been used for brutal dog fighting and hunting large ungulates. Because of his complex nature, the pit bull is banned in some European countries, as well as in Australia. In Germany, strict records are kept of all dogs of these breeds, and owners must regularly pay a fee for their maintenance. Those who are just planning to get a pit bull need to obtain permission from the police station.

The character of this dog depends entirely on its upbringing.. It is unacceptable to shout at the puppy or hit him - he will certainly remember this and may take advantage of the opportunity in the future to take revenge for childhood insults. This dog's memory is excellent. At the same time, with proper upbringing and proper training, the pit bull will remain a friendly, playful and inquisitive dog.

At the same time, owners who deliberately instill aggression in a puppy (ostensibly for protection) are inflicting on themselves disservice. A pit bull that cannot control its emotions may attack them themselves.

These strong, hardy dogs need an owner who is strict but fair, who can put the dog in the right framework and discipline it. As a rule, Rottweilers choose only one owner from family members, to whom they are selflessly devoted. But the dog also treats other family members with good nature. But the Rottweiler does not favor strangers, so it is better for friends and acquaintances to keep their distance from him. The dog may mistake any careless movement of the guest for an attack on the owner’s property. The dog treats pets condescendingly, especially if it has become accustomed to them since childhood. puppy age. But on a walk he can show aggression towards other dogs and cats, bursting into deafening barks and rushing towards the animal with far from friendly intentions.

This is a fighting breed dog, whose ancestors participated in bloody dog ​​fights, rat baiting, and hunting large animals. Therefore, the character of this dog is truly gladiator. The Bull Terrier is brave, even reckless, independent, active, but at the same time capricious, loves affection and attention to his person. If the owners love their “fighting” pet, often pet it, and praise it for its success in training, then the bull terrier will respond to them with friendliness and devotion. But you need to be prepared for your pet’s activity, restlessness, curiosity, and its ability to poke its nose everywhere. Long walks in the fresh air will help moderate the activity and mischief of a bull terrier.

This dog is often used for security purposes, so it can be found in car parks and guarded warehouses. Boxers' ancestors were used for bear baiting, thanks to their ability to close their jaws on an opponent's throat and hang on until they fell lifeless. The watchdog qualities of a boxer, with proper upbringing, are combined with friendliness towards household members, spontaneity, and touchiness. The boxer is very smart, and therefore knows how to achieve what he wants. This breed is considered dangerous due to the boxer’s distrust of strangers, upon seeing whom he begins to bark loudly and break loose from the chain.

Despite its balanced, friendly nature, the German Shepherd, like any other large breed of dog, can be very dangerous if handled incorrectly. There have been cases when a shepherd dog attacked its owners who shouted at it for some offense. You need to be careful if there are small children in the house. Puppies of this breed are very playful, and they may well choose a child as an object for play. At the same time, the puppy will play with the baby, as with his peers-puppies, biting and pouncing to throw him to the floor.

This dog is fearless, it subtly senses any hostility towards itself or towards its owner. Therefore, she can attack an ill-wisher without warning. Aggression can be shown towards people who are intoxicated.

This breed, developed in Pakistan, is still used in that country for hunting and dog fighting. This dog is very strong and resilient, has a powerful physique and a distrustful character. The Pakistani Mastiff is a rare and little-studied breed, but has become known as one of the most dangerous breeds dogs in the world. If they don’t like something, they immediately rush to defend their rights. An inexperienced owner will not suit the Pakistani Mastiff; only a firm hand can raise him correctly. You cannot have other animals in the house where the mastiff lives.

This dog radiates good nature and calmness with its entire appearance, but the character of the Chow Chow is very complex. Good-natured with family members, the dog can bite a stranger who has the temerity to pet it, or attack him, trying to crush him under himself.

It ranks tenth in the ranking of the most dangerous dogs, not so much because of its harmfulness and tendency to aggressive behavior, but because of its unbalanced character. Indeed, sometimes it is difficult to understand why a dog sitting good-naturedly on its owner’s lap suddenly begins to growl and bite painfully. Dog handlers explain this imbalance gene mutations breeds

Dog handlers in many countries around the world are unanimous in the opinion that most often the reason for the aggressiveness of dogs lies in humans, namely, in the improper upbringing of four-legged pets. Common mistakes include insufficient socialization, frequent and unreasonable punishment of the pet, short and inactive walks, and attacks from ill-mannered children. But not only these factors explain the behavior of the most angry dogs. Many breeds are on this list due to genetic predisposition.

Dominance aggression – the desire to become the leader of the “pack” – occupies a leading place among various types dangerous behavior. Owners of representatives of large breeds make active attempts to control such manifestations, but owners of medium-sized dogs do not. Although most bites and attacks on people are related to small dogs. Therefore, the list of the most evil breeds Dogs in the world include four-legged pets of various sizes.

South African Boerboels are powerful, large and dominant dogs. They are formidable and loyal guards who will always bark when a stranger approaches. Making excellent use of their enormous size and strength, they selflessly protect the owner and the entrusted territory.

Representatives of this breed get along well with other animals in the family and get along quite well with children. But as soon as they leave their home, they expand the boundaries of the territory they protect. They are aggressive towards other four-legged animals, and given the fact that their weight adult can reach up to 90 kg, the result of their attack can be serious injuries and even the death of an animal. Aggression can be either territorial, possessive, or dominant. If the owner cannot take a leading place in the hierarchy, then his pet will very quickly get out of control and turn into a monster.

In some countries, these fighting dogs are prohibited from breeding.

The pit bull is a representative of the fighting breed, whose aggressiveness over the past many years they have tried to reduce at the genetic level. Pitbulls are tireless fighters with a steely fight. Outwardly, they are often compared to the American Staffordshire Terrier, but representatives of this breed have a so-called fighting spirit, excitement, which makes them especially dangerous to other dogs and people.

Excitement during a fight allows them to act at the edge of their physical capabilities. Courage and extreme courage best characterize these dogs. Pit bulls are of the dominant type: if they are handled incorrectly or brought up gently, situations may arise aggressive behavior pet.

The Caucasian Shepherd is a common and very popular service dog, which is actively involved in the protection of various objects. Caucasians are enterprising, vigilant and distrustful of others. A well-trained dog can emerge victorious in a fight even with a group of attackers. He is able to sneak up unnoticed from behind and attack with lightning speed if he has identified a person as a trespasser on his territory. Shepherds react especially negatively to unbalanced people who are prone to scandals or are in drunkenness. It is not recommended to have a Caucasian for people who will not be able to dominate her and devote enough time and money to raising her.

Rottweilers are reliable and powerful service dogs in their constitution. They have a calm character and a balanced psyche. And yet, they also made it to the top of the most aggressive breeds. This is explained by their intolerance and anger towards other dogs.
