What Dog Has the Strongest Bite?

Top 10 Strongest Dog Bite Force

When discussing the strength of a dog’s bite, it is often measured in pounds per square inch (PSI), a unit that quantifies the pressure exerted. Among the various dog breeds in the canine world, those known for their strong bite force are typically large and muscular, with their bite capabilities having evolved for specific purposes such as hunting, guarding, or working alongside humans.

The breed that tops the list with the strongest bite force is often cited to be the Kangal, a guardian dog from Turkey, reputed for its protective instincts and has a bite force of around 700 PSI. Close contenders include the American Bandogge, Cane Corso, and the Dogue de Bordeaux. These breeds are not just known for their bite strength but also for their loyalty, intelligence, and ability to be trained, which makes them both respected and popular in their own right.

While measuring bite force can be a popular topic among dog enthusiasts, it’s important to remember that a strong bite doesn’t necessarily equate to aggression. Most dogs with a powerful bite are often gentle giants when properly trained and socialized. It is also pertinent for prospective dog owners to understand that a dog’s behavior is more influenced by upbringing and training than by its natural bite strength.

Strongest Dog Bite Force

Breeds With the Strongest Bites

The capacity of a dog's bite is measured in pounds per square inch (PSI), and some breeds have developed notably strong bite forces through selective breeding and their roles in working environments.

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.


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


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


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.


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.

Unraveling the Facts of Dog Bite Attacks

Understanding the significance of dog bite awareness is crucial to mitigating risks associated with dog bite incidents. This matter concerns public safety, the well-being of dog bite victims, and the importance of responsible pet ownership.

Dog Bite Attack Statistics

According to the Centers for Disease Control and Prevention (CDC), approximately 4.5 million dog bites occur in the United States each year. A subset of these bites results in serious injury. In 2021, 36 fatal dog attacks were reported in the US, showcasing the potential for grave outcomes stemming from encounters with dogs that have dangerous propensities.

Preventing Dog Bites

Prevention is a key aspect in reducing the incidence of dog bites. Through educational efforts, individuals can learn how to approach dogs safely and recognize warning signs of aggression. Some effective strategies include:

  • Do not approach unfamiliar dogs.
  • Avoid direct eye contact with a dog that appears threatening.
  • Teach children safe interaction techniques with pets.

Responsible Ownership

Responsible dog ownership is paramount to preventing dog bites. Owners should:

  • Socialize their dogs early to encourage comfortable behavior around people and other animals.
  • Train dogs to follow commands and to behave properly.
  • Secure their pets with fencing or leashes to prevent unintended encounters.

Owners must also understand the legal responsibilities they have and the potential consequences of dog bite cases, as they can be held liable for the actions of their pets.

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:


Unafraid to confront a potential threat.


Capable of distinguishing between normal and suspicious activities.


Able to follow commands quickly and efficiently.


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.


Have a natural instinct to protect their territory and people.

Doberman Pinschers

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


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:


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

Throughout history, dogs have served critical roles in societies worldwide, from guarding and herding to roles in warfare. Breeds developed over millennia have nuances in their characteristics shaped by the needs of their human companions.

Ancient Breeds and Their Roles

The Anatolian Shepherd Dog stands out as an ancient Turkish breed, displaying the quintessence of a working dog, honed by the pastoralist traditions of Anatolia. These canines were originally bred for the robust tasks of guarding flocks against formidable predators. The lineage of Mastiff breeds, infused with traits ideal for protection and combat, further exemplifies the purposive breeding in ancient times. In Rome and medieval Europe, for instance, they cemented their role as war dogs, valued for their might and loyalty.

Development of Modern Breeds

As societies evolved, the functional roles of dog breeds expanded, prompting selective breeding to accentuate the desired traits. Modern breeds have emerged from their ancient predecessors through careful selection for attributes such as temperament, size, and strength. Mastiff breeds, once bred for battle, found new purpose in peacetime activities, yet they retain the powerful jaw strength that once made them formidable on the battlefield. The Anatolian Shepherd's traits have similarly been fine-tuned, with a focus on maintaining its status as a premier guardian, reflecting an unbroken line from its historical roots.

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.
