What Dog Has the Strongest Bite?

Top 20 Strongest Dog Bite Force

No matter what kind of dog a person chooses as a pet, it is important to know that any dog can bite. Even if it has never demonstrated any aggression before, whether it is provoked or not, it is vital always to exercise caution around these animals. The strongest dog bites are listed below in a dog bite force comparison. This dog bite strength data provided by dog bite statistics reveals the dog breeds with the strongest bite. You can review dog bite laws by state and legal recourse for dog bites if you or a loved one have been bitten.

Top 20 Strongest Dog Bites

Kangal

1. Kangals

At 734 PSI, Kangals, a Turkish dog breed, have the most powerful dog bite of any breed. This dog breed is commonly chosen as a guard dog, especially for protecting herds of animals, such as sheep, from predators. 

The Kangal breed is strong, agile, and loyal, though proper training as a pup can make sure they don’t unnecessarily bite invited guests. When they are trained young, they are often gentle with children and even other animals. With a bite force this strong, Kangals can do serious damage to anyone they attack.

American Bandogge

2. American Bandogge

The bite force of an American Bandogge, or Bandog Mastiff, is 730 PSI, making it the second strongest dog bite among all known breeds. Its breeding history over the centuries may provide a clue to its aggressive demeanor. Linked to Pitbull Terriers and Neapolitan Mastiffs, they have long been trained to guard and defend their owners and property. WIth the right amount of love, they can be incredible pets, but in the wrong hands, they can viciously bite and cause serious injury to anyone they perceive as a threat.

Cane Corso

3. Cane Corso

The Cane Corso breed ranks third for strongest dog bites at 700 PSI. Hailing from Italy, this breed is famous for being intelligent, loyal, and absolutely fearless. Since it is a highly protective dog, it is often used as a guard dog. A quick learner, the Cane Corso is able to be trained quickly for this duty. When it bites, it can be incredibly aggressive in its pursuit, making it vital to exercise extreme caution in its presence.

Dogue De Bordeaux

4. Dogue De Bordeaux

You may know this breed as the French Mastiff or Bordeaux Mastiff, which is the result of an ancient lineage. The Dogue De Bordeaux has a storied history of being used for carrying heavy items, pulling carts, and protecting other animals. While it is a mostly pleasant creature, one that tends to be kind and gentle with small children, it does boast a strong bite of 560 PSI. It is more typical for the Dogue De Bordeaux to only attack when provoked, making it a safe choice to keep as a pet for families.

Tosa Inu

5. Tosa Inu

The Tosa Inu is a Japanese Mastiff breed that is distinguished from other Mastiffs by being more reserved than its playful contemporaries. The temperament of the Tosa Inu is fairly even but it is essential to socialize them while they are young. Without this key integration, they can be very aggressive, especially to other dogs. With a bite force of 555 PSI, it is critical to be cautious when owning one or while visiting anyone who keeps the Tosa Inu as a pet.

English Mastiff

6. English Mastiff

English Mastiffs are often referred to as just a Mastiff breed, one that was often utilized by the military. They’re loyal dogs that have a kind spot in their hearts for their owners and families. Their large size certainly makes them scarier than they appear and while they are usually sweet, they can cause serious damage with their bites. The force they can exert is 550 PSI, one that can easily injure an unsuspecting friend, family member, or neighbor.

Dogo Canario

7. Dogo Canario

While the English Mastiff has a stronger bite force, it is far gentler than the Dogo Canario, also known as Perro de Presa Canario. The Dogo Canario is an extremely aggressive breed and one that should be treated with caution. The structure of its body makes it a more than capable creature for guarding property. A dog like this needs plenty of space to move around and an owner that makes sure to establish themselves as the alpha in the family to keep it from becoming overly dominant. Due to the tendencies it has for aggression, these dogs are not generally recommended as pets. Be careful if you encounter one as they have a bite force of 540 PSI.

Dogo Argentino

8. Dogo Argentino

Originally bred for hunting, the Dogo Argentino is highly protective of its caretakers. The bite force of this breed measures at 500 PSI, making it strong enough to take on large game animals. It also happens to be incredibly large in size and fast on its feet. While the Dogo Argentino is a naturally aggressive breed, they don’t attack people at random. When trained and socialized early, they can become a devoted pet that is ideal for anyone who hunts or needs a strong guardian to keep the homestead safe. However, if someone comes on a property without invitation, they may find this dog can bite off much more than it can chew.

Leonberger

9. Leonberger

Leonbergers are a German breed with a large size and fluffy coats of fur. They can be playful and gentle creatures, making them a good choice to train as therapy dogs. Even though Leonbergers are fairly loving in nature, their large size and capacity for strong bites mean they should always be carefully supervised. A Leonberger can bite with a force of 399 PSI, making for a very painful experience if this pup feels the need to exert its strength.

Rottweiler

10. Rottweiler

While many of the dog breeds on this list are lesser known, the Rottweiler has great notoriety for its intimidating presence. These strong dogs have a strong bite of 328 PSI. That might not be the strongest bite, but Rottweilers are capable of causing severe injuries if they feel compelled to attack. They must be properly trained and socialized to minimize the risk of owning this breed of dog.

American Bulldog

11. American Bulldog

Most people might feel like they need to worry more about being slobbered on by an American Bulldog rather than worrying about being bitten. It’s certainly true that American Bulldogs are gentle animals, making them a prime choice as a household pet for families. However, don’t be complacent around this breed. When they aren’t properly cared for or left to their own devices, they can be destructive. With a bite force of 305 PSI, they are more than capable of causing damage if they decided to chomp on anyone or anything.

German Shepherd

12. German Shepherd

There is a good reason why German Shepherds are often trained to serve on the police force. These dogs are incredibly smart and reserved around strangers. It is difficult to distract a German Shepherd from its tasks or the commands their owner gives. This breed isn’t exactly friendly with other dogs or animals, and when it is focused on guarding or taking down a criminal with its bite, it can exert a force of 238 PSI. It’s certainly less force than other breeds, but rest assured, it will be a painful experience for whoever is bitten by those jaws.

Pitbull

13. Pitbull

Even though Pitbulls can be loyal and kind dogs that are easy to train, they have earned a dangerous reputation for bites and attacks. It is important for owners of this breed to train and socialize them well early on, which isn’t difficult as Pitbulls are one of the easiest breeds to train. Pitbulls bite with a force of 235 PSI, which is plenty to cause harm. The only reason they have such a bad name is due to irresponsible breeders and owners who fail to give them the training they need.

Boxer

14. Boxer

Another drool-heavy breed that is often a prized pet, Boxers usually look very formidable. These dogs are extremely gentle and loving and they easily get along with other pets and small children. The key thing to know about Boxers is that they are smart dogs that are eager to obey; however, they can become anxious or restless when not given enough attention. This may compel them to bite and with a force of 230 PSI, Boxers can easily hurt someone with their jaws.

Doberman

15. Doberman

A Doberman guarding the property can be an imposing sight. This animal is as quick as it is sleek, and it’s a loyal breed of dog that is perfect for protection. While they are loving and playful, they are more ferocious than other breeds. Dobermans can become destructive when left to their own devices, and may even exhibit that with their bite force of 229 PSI. Additionally, if they’re being considered as a pet for a family, children will be much safer in their presence if they live with them from birth.

Alano Espanol

16. Alano Español

Compared to dogs with stronger bites, the bite force of this breed is only 227 PSI. However, these large dogs are always looking to be the alpha of the pack and have an aloof demeanor that is beneficial for taking assertive action. The Alano Español was historically used to bait bulls in Europe and in battles in Middle Eastern regions. Despite aggressive tendencies, they obey their owners when they are trained properly, which is encouraged to prevent them from chomping down on visitors.

Dutch Shepherd

17. Dutch Shepherd

Historically used for herding, Dutch Shepherds are among the smartest breeds for this task. In the absence of having livestock to manage, they’ll gladly offer their services to corral other animals, kids, and adults. The trick with these shepherds is to always provide dominant direction to help them stay focused on their job. One of the biggest concerns with Dutch Shepherds is that they have a powerful bite force of 224 PSI, which is not even the strongest on this list. Given their unpredictable nature around small children and other animals, caution is advised when owning this dog breed.

Chow Chow

18. Chow Chow

Chow Chows are large, beautiful dogs that are incredibly powerful. They have a bite force of 220 PSI but they can exert force in other ways. They’re not recommended to keep around children as kids have a tendency to be too loud and unpredictable for this animal. Chow Chows are highly stubborn, making them a challenge to train. They can be used as guard dogs and are truly ideal when you need an extra line of defense. Their aloof personalities are a match for the task of protection but owners must beware that these dogs can be a major danger to others.

English Bulldog

19. English Bulldog

The English Bulldog is a slobbery breed that can be friendly most of the time. They find favor with children and other animals even though they aren’t very high in energy. Even though they can be a bit lethargic, it is imperative to give them proper training. They can certainly test your patience as English Bulldogs tend to be stubborn so it is ideal to be firm. Without training, these dogs can be prone to nipping and biting; with a bite force of 210 PSI, it is the responsibility of English Bulldog owners to ensure their pet doesn’t attack.

Malinois

20. Malinois

Take a quick glance at a Malinois and you may mistake it for a German Shepherd. You wouldn’t be too far off the mark as the Malinois is also called a Belgian Shepherd. Like the German Shepherd, it is smart, brave, and prone to staying focused on a task. When it is given duties, especially in an outdoor setting, it will thrive. A Malinois must be properly educated and socialized to protect others. When it has no training, it can become one of the most aggressive breeds around. Even though its bite force measures at 195 PSI, the lowest force on this list, its propensity to act out when not trained well makes it one of the most dangerous dog breeds.

Mastiff Breeds

Mastiff breeds are renowned for their immense size and power. Among them, the English Mastiff stands out with one of the most powerful bites recorded in the canine world, possessing a bite force of approximately 550 PSI. These gentle giants, despite their formidable jaws, are often known for their loyalty and docile temperament when well-socialized.

American Pit Bull Terrier

The American Pit Bull Terrier is a breed commonly recognized for its strength and courage. Their jaw strength is impressive, with a bite force measuring around 235 PSI. This breed's strong bite is often overshadowed by their affectionate and loyal nature towards their owners.

German Shepherd

German Shepherds are not only popular for their intelligence and versatility but also for their strong bite, which is measured at about 238 PSI. Originally bred for herding and guarding, these dogs carry a strong bite as a natural trait for protection work.

Cane Corso

Another breed with a notable bite force is the Cane Corso. This Italian mastiff-type breed is muscular and robust, possessing a bite strength of 700 PSI, which ranks them amongst the strongest biters in the canine world. The Cane Corso's bite is a trait that has been historically useful in their roles as protectors and hunters.

Other Noteworthy Breeds

Other breeds also manifest a significant bite force. For instance:

  • The Rottweiler, with a strong bite force of 328 PSI, is known for its guardian instincts.
  • The Dogue de Bordeaux, another mastiff breed, also comes with an impressive bite around 556 PSI.
  • Additionally, the Kangal is often cited for having one of the highest bite forces, reaching up to 743 PSI.

Each of these breeds has developed a strong bite force tailored for specific tasks, from guarding to herding. It's important to remember that bite force alone does not determine a dog's temperament or likelihood of aggression. Training and socialization play crucial roles in the behavior of any dog, regardless of its bite potential.

Wolves

Comparative Bite Forces


When discussing bite forces, it's crucial to consider the measurements in pounds per square inch (psi), as this gives a clear standard for comparison.

Canines Versus Other Species

The comparison of canine bite force with that of other species sheds light on the relative power of dogs in the animal kingdom.

  • Wolves have powerful jaws with an average bite force of around 400 psi, which reflects their adaptation to hunting and subduing large prey in the wild.
  • Among domesticated dog breeds, the bite force can vary. Mastiffs and Rottweilers are notable; for instance, the English Mastiff has a bite force of about 552 psi. However, it's the Kangal, a shepherd dog, that surpasses others with a bite force that can reach up to 743 psi.
  • When comparing these figures to other animals, it's evident that dogs are not at the top in terms of bite strength. For example, hippopotamuses exhibit an astounding bite force of about 1,800 psi, while crocodiles stand at the pinnacle with bite forces exceeding 3,700 psi.
  • In direct comparison to their wild counterparts, domestic dogs generally have a lower bite force. For instance, although the aforementioned Kangal is highly impressive among domestic breeds, it still does not reach the bite strength of larger predators such as lions, which can exert around 650 psi.

This data highlights that while some dogs have considerable bite strength, especially in a domesticated context, other species in the animal kingdom possess a more formidable bite.

Large and Muscular Dog Breeds


When discussing the strength of a dog's bite, it's essential to consider large and muscular dog breeds, which often have the physical attributes that contribute to a powerful jaw. The English Mastiff possesses not only a massive body but also one of the strongest bites. Weighing up to 230 pounds, they are known for their protective nature.

The French Mastiff, also known as the Dogue de Bordeaux, exhibits a broad, muscular build with a substantial head, contributing to its bite force. Their temperament is calm yet assertive, a key trait that complements their physical prowess.

Another noteworthy breed is the American Bulldog, which showcases a sturdy physique and a strong bite. Originally bred for farm work, this breed combines agility and strength seamlessly.

The Doberman Pinscher is recognized for its alertness and loyalty alongside its muscular frame. Although they are not as heavy as mastiffs, Dobermans possess a considerable bite force, a byproduct of their athletic build.

Breed Average Weight Notable Trait
English Mastiff 130-230 lbs Protective nature
French Mastiff 99-110 lbs Assertive temperament
American Bulldog 60-120 lbs Agility combined with strength
Doberman Pinscher 60-100 lbs Athletic and loyal

These breeds exemplify a combination of size and muscle, which correlates with a more potent bite. It's this balance of mass and muscle that often puts them in the spotlight when discussing bite strength. It's important, however, to note that responsible breeding, training, and care play a significant role in the temperament and behavior of these powerful dogs.

If you’ve been injured or attacked by a French Mastiff, Doberman Pinscher, English Mastiff, American Bulldog, Pit Bull, or any other dangerous dog, we encourage you to hire legal representation. This is the best way to get the financial compensation you need to deal with the aftermath. A well-reputed dog bite lawyer will help you better understand your next steps in order to get the compensation you deserve.

Understanding Bite Force


The bite force is a critical metric in assessing the strength of a dog's bite. It is quantified in pounds per square inch (psi), which measures the pressure exerted over one square inch of area.

Measuring Bite Force

The bite force is measured using specialized equipment that can withstand the pressure of a dog bite. The tools record the maximum force exerted by the dog's jaws during a bite. The measured force is then converted into psi, providing a standardized unit for comparison. The strength of bite can vary between individual animals, with some breeds recording more powerful bite force than others.

Factors Influencing Bite Force

Genetics

An integral factor is the genetic makeup of the dog, with certain breeds inherently possessing a stronger bite.

Age

Adult dogs generally have a more developed bite force than younger dogs. Average adult dogs may exhibit bite strength significantly different from that of large breeds renowned for their impressive bite force.

Health

A dog's health can impact bite force, particularly dental health and the muscle structure surrounding the jaws.

Training and Activity

Dogs actively trained to use their bite effectively, such as those in protective services, often develop a more powerful bite force than average household dogs.

Training and Behavior


While the physical capability of a dog plays a vital role in the strength of its bite, training, and behavior are equally important in how that force is controlled and applied.

Influence of Training on Bite Force

Proper training is crucial in ensuring a dog understands how to moderate its bite force in different situations. For instance, pit bulls have a reputation for having a strong bite, but with proper training, they can learn to control their natural tendencies. A study comparing the bite forces of dogs trained for protection with those of family pets found that properly trained protection dogs exhibited more restraint and precision in their bite force.

Behavioral Considerations

Dogs that are bred specifically for certain traits may display unique behavioral patterns that influence their bite force. It is essential to understand that a dog's behavior is not solely determined by its breed but also by its environment and upbringing. For example, a dog that has experienced poor socialization or traumatic events may exhibit a higher propensity to bite due to fear or aggression, regardless of its breed.

Understand the Dog's Background

  • Traumatic past may lead to increased biting.
  • Early socialization can mitigate aggressive behavior.

Consistency in Training

  • Maintains control and reduces the likelihood of harmful bites.
  • Intermittent reinforcement can confuse a dog and lead to unpredictable behavior.

Implementing consistent and specialized training regimes tailored to each individual dog can significantly reduce the incidence of dog bites and ensure that the dogs remain well-behaved and safe around people and other animals.

The Role of Dogs as Guard Animals


Dogs have long been valued for their vigilance and protective instincts, making them excellent candidates for guard animals in various settings.

Guard Dog Traits

Traits that are essential in guard dogs include alertness, loyalty, and a natural instinct to protect. These dogs often exhibit a strong presence and a formidable bark, which can deter intruders. They are typically:

Confident

Unafraid to confront a potential threat.

Intelligent

Capable of distinguishing between normal and suspicious activities.

Obedient

Able to follow commands quickly and efficiently.

Strong

Possess physical strength and stamina.

Breeds Ideal for Guarding

Several dog breeds stand out as exemplary guard dogs due to their physical attributes and temperaments. Among them are:

German Shepherds

Known for their intelligence and versatility, they excel as both guard dogs and family pets.

Rottweilers

Have a natural instinct to protect their territory and people.

Doberman Pinschers

Fast and powerful, these dogs are alert and make excellent guard dogs.

Bullmastiffs

They combine great strength with a loyal and protective nature.

The breeds listed above are well-regarded for their ability to serve as both protective dogs and, in many cases, great family pets.

Training Guard Dogs

Effective training is crucial for preparing a dog to fulfill the role of a guard animal. Key aspects of training include:

Socialization

Exposing the dog to various situations to prevent over-aggressiveness.

Obedience Training

Establishing commands that the dog will follow reliably under any circumstances.

Protection Training

Teaching the dog to detect, challenge, and neutralize threats when necessary.

Professional training ensures that a guard dog can discriminate between normal behavior and genuine threats, reducing the likelihood of inappropriate reactions. German Shepherds, often also used as war dogs, respond particularly well to such training, reinforcing their reputation as an excellent guard dog breed.

Historical Significance of Dog Breeds


Dog breeds play significant roles within human societies, from providing companionship in homes to performing duties in various sectors. Their integration reflects their adaptability and the unique bonds they form with humans.

Family Companions

Many dog breeds are considered great family pets due to their temperament and behavior. They provide company, enriching the lives of dog owners with loyalty and affection. For instance, Labrador Retrievers and Golden Retrievers are renowned for their friendly nature, making them top choices for households with children. Beyond the joy they bring, these dogs also contribute to a family's wellbeing, often encouraging more active lifestyles through regular walks and playtime.

Common Traits of Family Companion Dogs:

Gentleness, crucial for homes with young children

Trainability, allowing for smooth integration into household routines

Social nature, fostering strong bonds with family members

Working and Service Dogs

Dogs have long been essential in various working roles and as service animals, demonstrating a wide range of skills that benefit society. Police forces utilize breeds such as the German Shepherd for their intelligence and discipline in roles from tracking to apprehension. Meanwhile, Border Collies are still the breed of choice for herding livestock due to their exceptional agility and herding instincts.

Roles of Working and Service Dogs:

Assistance for the disabled, e.g., guide dogs for the visually impaired

Search and Rescue (SAR), where breeds like the Bloodhound excel due to their keen sense of smell

Therapy dogs in healthcare settings, utilizing breeds known for their calming presence

In both capacities as family companions and working dogs, breeds are carefully chosen by dog owners based on how well they fit into their intended role within society. The connection between dog owner and pet is symbiotic, with each providing support and enhancing the lives of the other.

The Debate Over Dog Fighting


Dog fighting is a practice that involves pitting two dogs against each other in a fight for the entertainment and often for the financial benefit of spectators. This activity is illegal in many parts of the world due to the inherent cruelty and moral implications. The dogs involved are typically trained to enhance their aggressive behavior, which raises significant ethical questions.

Legal Status

In countries where dog fighting is outlawed, it is considered a serious crime. Convictions often lead to heavy fines and jail time.

Impact on Dogs

Dogs used in fighting rings endure physical and mental trauma. Many are bred and conditioned for increased aggression, which can make rehabilitation challenging.

Advocacy Against Dog Fighting

Numerous animal rights groups actively campaign against dog fighting. They raise awareness about the barbaric nature of the practice and its consequences on the well-being of dogs.

Animal Welfare Laws

There is a universal push among activists to strengthen animal welfare laws to prevent dog fighting.

Rescue Efforts

Organizations work to rescue dogs from fighting operations and rehabilitate them so they can have a chance at a normal life.

Arguments of Proponents

Some proponents argue from a traditional or cultural standpoint, though these views are increasingly marginalized given international consensus on animal rights.

Dog fighting is unanimously recognized as abusive, with far-reaching effects on the involved dogs' psyche and health. Their aggressive behavior is often irreversibly molded by the environment in which they are raised and trained. As laws become stricter and enforcement more rigorous, the number of dog fighting cases is expected to decline.
