The strongest jaws in the animal world. The strongest jaws in the animal world. Not with just teeth

Thanks to the work of dog breeders, today there are more than four hundred dog breeds. Some, such as the Pekingese, have seen the rise and fall of ancient empires, while others are more recent. Guard dogs occupy a special place; they are timeless and fashionable; people love them as loyal friends and reliable guards.

When choosing a dog breed that will play the role of “security” or house watchman, special attention is paid to speed, distrust, and the ability to make independent decisions. Last but not least is the moment who has the most strong jaws. What breed of dog has a powerful bite that can stop an attacker?

Not with just teeth

Which dog bites the hardest? The one that really wants to bite. It looks like a joke, but only partly. The strongest jaws in dogs are not a guarantee that they will be used. There are breeds in which aggression is genetically absent - Labrador, Golden Retriever. Although they are not inferior in strength and weight to the German Shepherd, these dogs are not capable of attacking humans.

Among representatives of guard breeds, it is rare, but still there are good-natured specimens that do a poor job of protecting their owner or property. In this case, the problem lies in education, under the guidance of an experienced dog handler in the Rottweiler, or perhaps awakening the inherent potential.

Anatomy of a bite

In essence, a dog is a structure made of bones and muscles. Looking at it purely from an engineering point of view, you can determine which breed of dog has the strongest jaws. There is a clear relationship between physiological characteristics.

To “bite” the pet must have a massive head with a large mouth. To maintain balance, such a muzzle should be attached to a short neck, which reduces the load on the spine. The optimal ratio is equal in size to the cranial and jaw regions. In this case, the grip is quite deep and strong. In breeds with an elongated muzzle, for example, Russian greyhounds, with the strength of chewing muscles equal to the Doberman, this is why the bite will lose.

Bulldogs have short jaws great strength, but at the expense special structure they have a so-called “death grip”. The area of ​​capture and bite is reduced. Breeds with a shortened nasopharynx have a weak sense of smell, and when they cling to an enemy, they lose maneuverability and become vulnerable. It's difficult for them to bounce back quickly.

Golden mean

Knowing the aspects that influence the bite, you can understand that the strongest jaws are in dogs of those breeds that have a fairly large head with a wide opening of the jaws. In addition, the guard must have a sufficient level of aggression and courage to use his formidable weapon. It was this rule that guided people when they bred protective guard breeds to protect people and their property. In addition, guard dogs must have a calm disposition, be easy to train, and be devoted to the owner’s family. An overly excitable dog does not respond well to commands and can turn from a protector into a source of problems.

Dogs have the strongest jaws. Top breeds

There are breeds that are recognized as the best guard dogs. They have a strong bite and a desire to protect the owner; his property successfully complements each other. Some of them appeared during life, the main breeder was nature itself, living conditions did not allow puppies with insufficiently strong jaws and character to survive. Others were bred by humans, but are not inferior in protective qualities and the ability to prove with their teeth to the owner’s enemy that he committed stupidity by encroaching on his property.

The strongest jaws in dogs of this breed are combined with large sizes bodies. The height of a male dog at the withers is 70 cm or more.

In addition, the representatives of the CAO have the blood of herding and fighting breeds, which makes them vigilant, but balanced guards. Nature carried out selection under harsh conditions, and people polished the result. As a result, the dogs turned out to be ideal family members, kind to children and other animals, they are merciless towards large predators and uninvited guests. On the far teeth the bite force is at least 300 kg.

Cane Corso

When talking about which dog has the strongest jaws, it is impossible not to mention this breed. True guards clearly divide the world into “us” and “strangers”.

You can safely entrust a child to them; they will lay down their lives to protect the owner’s offspring. Defeating a dog consisting of 50 kg of iron muscles, possessing agility, fearlessness and incredibly sharp fangs is not an easy task. In the family circle the animal is calm and good-natured.

Capable of scaring away with just one look. Huge, lion-like dogs are able to make independent decisions and act according to the situation.

They should not be allowed to dominate; in this case, “Caucasians” are obedient and manageable. They do not have excessive aggression, but no one is allowed to offend the owner or encroach on his property. In terms of bite force, it is not inferior to the two previous breeds - 13.5 atmospheres.

Rottweiler

More of a bodyguard than a watchman. He is people-oriented and needs their company. Order is strictly maintained in the controlled territory.

Self-possessed, calm, adequate, independent in decision-making. This breed requires a strict but friendly atmosphere and careful training. An excellent companion for adults and older children. The Rottweiler is friendly towards children, but may not distinguish between rough play and may react too violently. Compression force - 146 kg.

Excellent sense of smell, lightning-fast reaction, sensitive ears and strong jaws - features breeds It is worth adding here a remarkable intelligence, love for work and learning - and we will get the ideal dog.

The shepherd dog does not choose one owner; it obeys all family members perfectly. She must have a job - guard the house, look after the children, accompany the owner. Without this, she gets bored and the dog's character deteriorates. The force of teeth pressure is from 120 to 315 kg.

Don't forget about pit bulls, bull terriers and American Staffordshire terriers. The jaw strength of these dogs is 120 kg or more. They have a strong grip, quick reaction, and are extremely maneuverable. It won't be easy to escape from them. However, dogs of these breeds, with adequate training, are absolutely not hostile to humans and will not attack without a serious reason.

It is impossible to say for sure which breed has the strongest jaw in a dog. There are dozens of breeds in the world that are suitable for protection. And a representative of any of them in dangerous situation can set a record that no one will know about.

The main force of a human bite comes from the chewing teeth and muscles, it is extremely powerful and reaches a maximum pressure of over 113.4 kg. In general, the average human bite force in kg is 45-68. Some sources report that people do not use their full force when chewing food.

In fact, our teeth are strong enough and the bite force of a person is enough to chew on a cinder block. Amazing, right?

A human being bitten by a human is obvious, but in some cases the victim is unaware
(for example, when the victim was drunk) or does not want to tell others who bit him (for example, because of a hand injury during a fight).

Be careful with cuts above the knuckles if they occur in combat, especially when the cuts were caused by another person hitting the mouth.

Why is a human bite dangerous?

Is it possible to become infected with HIV through a human bite? In addition to tissue trauma, infections due to oral flora are added, this becomes a serious problem for the body.

We bring to your attention ten animals with the most powerful bites in the animal world. There are animals that would most likely be in this top ten, but the strength of their bites has not yet been measured due to the complexity or high cost of measurements. Eg, White shark, which should have a very strong bite, but precise measurement it does not exist except for theoretical estimates. Tasmanian devil has the strongest bite relative to its size - 13.6 atmospheres (14 kilogram-force per square centimeter), which is only slightly more than that of hyenas.

10. Leo
42 kgf per sq. cm

An unexpectedly low place for the king of beasts. Lions are the only social felines in the world. They almost always hunt together, which may be why they did not have to develop strong bites during their evolution. Another reason may be that they kill their prey by biting the trachea, which does not require a strong bite. Lions hunt at any time of the day, but most often at night. They can go without water for five days, but prefer to drink daily if possible.

9. Tiger
74 kgf per sq. cm


Tigers, the largest members of the cat family, hunt alone. The size of tigers reaches 3.3 meters and weighs about 300 kilograms. They hunt mainly at night. Like lions, they usually kill their prey by grabbing the throat, thereby cutting off the flow of blood and air. They have a strong bite that is almost twice as strong as a lion's bite. Currently, the number of tigers kept in captivity is greater than the number of wild tigers. They generally avoid people, but in some conditions they can attack people and livestock.

8. Spotted hyena
77 kgf per sq. cm


Hyenas have one of the strongest bites in the animal kingdom - 77 kgf per square centimeter. With their bite they can even bite through the bones of giraffes. Most likely, it is the fact that hyenas are scavengers that causes their strong jaws. To get to the bone marrow that doesn't interest large predators, you need strong jaws.

Although hyenas look like dogs, they are actually closer to cats and belong to the suborder Felidae rather than Canidae. Hyenas can kill a dog with one bite. Despite popular belief, hyenas do hunt themselves, and lions, ironically, often steal their prey. Like lions, hyenas are social animals.

7. Grizzly
84 kgf per sq. cm

This subspecies of brown bear, living mainly in North America, is known for its enormous size and aggression. Despite their size, grizzlies can reach speeds of 56 kilometers per hour. Grizzlies mainly feed on nuts and berries, but sometimes they also hunt. In Yellowstone National Park, for example, they hunt other animals.

Grizzlies are considered more aggressive than other bears. This is due to the fact that due to their size they cannot climb trees, and therefore they have developed such a unique defense mechanism. In addition to aggression, during the course of evolution, grizzly bears have also developed strong jaws, which help them protect themselves from wolves and other predators. Grizzlies weigh between 300 and 500 kilograms. They can be dangerous to humans if they encounter a mother with cubs, but grizzly bears do not view humans as prey.

6. Gorilla
91 kgf per sq. cm

Gorillas eat plant foods, so it’s strange to see them in this top ten. In fact, there is little surprise here. Gorillas feed on tough and durable plants such as bamboo - to do this they had to develop strong jaws and neck muscles.
Gorillas used to be seen as big scary animals, but in Lately Increasingly, they are seen as “gentle giants.” They are our closest relatives (only chimpanzees are closer), and their population is rapidly declining (there are only 700 mountain gorillas left in the wild). Gorillas can climb trees, but most often they prefer to be on the ground. They usually live in communities of 30 individuals, led by a dominant old male. Gorillas are predominantly gentle creatures and pose no danger to humans.

5. Hippopotamus
128 kgf per sq. cm

Hippos are large and strong herbivores. They are one of the most feared animals in Africa. Hippos are aggressive and defend their territory by capsizing small boats and attacking people. The bite of a female hippopotamus was measured, since males are too aggressive, but even the force of her bite reached a huge value of 128 kgf per square centimeter. The word "hippopotamus" comes from Greek language and means "water horse". The closest relatives of hippopotamuses are whales and cows. They belong to the order Artiodactyla, which also includes horses, camels and goats.

4. Jaguar
141 kgf per sq. cm


Jaguars have the strongest bite of all cats and mammals in general. They live mainly in Northern and South America. Jaguars kill by biting the victim's head. Like many other big cats, jaguars hunt alone. There are known cases where jaguars killed anacondas and caimans. Jaguar bites are so strong that they can even bite through the shell of a turtle. The word "jaguar" comes from the American Indian language and means "one-leap kill." Although jaguars are smaller than their African and Asian relatives, they are the largest feline in the Americas.

Jaguars are thought to have disappeared from the southern United States more than 100 years ago, but rumors have recently surfaced that a population may be developing in Arizona. Largest quantity Jaguars live in Belize, on the Cockscomb Basin Reservation.

3. Mississippi alligator
149 kgf per sq. cm

Their natural habitats are Florida, Texas, Louisiana, North and South Carolina, Georgia and Alabama. Crocodiles also live in these same areas. They feed mainly on fish, turtles and small mammals. A recent National Geographic study estimated an alligator's bite at 149 kg per square centimeter, but their bites may be stronger since the study did not measure the largest member of the species.

2. Saltwater crocodile
260 kgf per sq. cm


Saltwater (or saltwater) crocodiles have the strongest bite of the specimens in the National Geographic study. True, they didn’t even choose the biggest crocodile. If you estimate the bite force of the largest crocodiles, you will most likely get a bite force of 500 kgf per square centimeter.

The range of saltwater crocodiles extends from eastern India to southeastern Asia and northern Australia. Their “diet” includes buffalo, fish and even sharks. Australians affectionately call these crocodiles “salties,” but there is nothing gentle about these giants. They are responsible for more attacks on humans than any other crocodiles (except the first place in this top ten).

1. Nile crocodile
352 kgf per sq. cm


In a National Geographic experiment, Nile crocodiles' bites were weaker than those of saltwater crocodiles, but most other sources state that Nile crocodiles bite with a force of 352 kg per square centimeter. Nile crocodiles are usually about the same size as saltwater crocodiles and have the same bite force. Both of them can take first or second place on this list, since it is difficult to choose which individuals to test and difficult to figure out how to conduct the experiment correctly.

Nile crocodiles primarily feed on fish, but like their relatives, they will attack any animal that happens to be nearby, such as zebras, birds and small hippos.
