Have you ever wondered which breed of dog has the strongest bite? We have listed the 10 dogs with the most powerful bites, according to the PSI rankings.
PSI: Pound per Square Inch (Pound per square inch “or” Pound-force per square inch)
Dogs with a strong bite have superbly developed grip and jaw strength, which provides the animal with superiority in a fight with a stronger and stronger opponent. It is not for nothing that they say about some breeds “They have a stranglehold.” Such dogs have a rather tough character and require constant discipline. They feel and understand their bite force, therefore they need a responsible attitude from the owner.
Let’s face it, a dog’s mouth is like the swiss army knife for dog tools. He picks up his toys with, eats with, opens the lid of the trash, tears up the bag of treats, drools, barks, smiles and licks … But he can also bite when he feels distressed, personally or as a member of the pack threatened and, while some will pinch to warn, others will have a little more strength. PSI is what is used to measure the bite force of a dog and to give it a little context, humans have a PSI of about 120-140, a gray wolf of about 406 and a Grizzly bear lands in the range of 1,250 PSI. So where do our canine friends fall and which ones have the strongest bite?
What dog has the strongest bite?
How dog’s jaw pressing force is measured?
Bite force is measured in newtons (N), which can be converted to kilogram-force (1 kgf = 10 N). For fighting dogs, it is important to know this parameter, because it speaks of a strong jaw of the animal, which meets the standards of the breed. Additionally, the strength of capture is learned during the training of assistance dogs, which are then used to incapacitate criminals.
The pressure force of the dog’s jaw is measured in several ways. The simplest, but not very precise – the dog is forced to grab a wooden pine block during the attack, then the depth of the bites is measured. Now dog handlers refuse such a method and use special sleeves with built-in sensors.
It is impossible to measure the force of a dog’s bite at home, as it is within the reach of specially trained people using special armbands with built-in sensors.
It is important to understand that when indicating the grip strength, an average number is used, since in different parts of the jaw the pressure on the object of the bite will be different. The deepest puncture is made, of course, by the fangs, but above all the victim is pressed by the dog’s molars; the incisors have less force because they are farthest from the muscles responsible for closing the jaw.
Note: In general, in the world, there are two types of jaw strength measurement. For example, in some countries the unit of measurement is Pounds Per Inch or PSI. In others, using the familiar SI system, newtons are used – one newton equals 10 kgf.
18. Malinois dog
The Malinois (Belgian Shepherd). This worthy look-alike of the German Shepherd is from Belgium and was bred for herds – so you know that hunting and biting can be part of the package. Despite a somewhat voluntary streak, this handsome dog is as intelligent as his doppelganger and learns quickly – which is good because with a bite force of 195 PSI, you’ll want his flock desire to be a thing of the past.
The Bulldog has a short, stocky body and relatively loose skin, especially on the head, neck and shoulder blades.
Its fierce appearance usually gives a false impression. These dogs are generally affectionate, calm and quiet, although they are also tenacious when they want something. They are generally very patient with children and make excellent pets, but they are not very active dogs.
When the bulldog gets angry however, it is an animal to fear. When defending his territory, his family or his property, he is a brave dog and capable of causing much damage.
The bite force of the Bulldog is 210 PSI.
The danger of dog bites is not measured only by the strength of clenching your teeth. It also plays a role for how long the dog can keep the jaw under maximum tension, what tactics of attack the dog has, how much at the moment of aggression it remains controlled by its owner (whether the object will let go at the first order ). For example, Staffords and Pit Bulls have a lower bite force than many breeds, but their “killer” instincts are overdeveloped – when biting, dogs don’t just defend themselves or scare , they seek to kill.
16. Chow Chow
Now, this cheerful-looking boy with a fluffy face and purple tongue is known to have a little “study” when it comes to other dogs. Like many dogs, the chow chow was originally bred for hunting, so it also has a bite where its bark is found. Make sure you socialize him from the start and with a bite force of 220 PSI, make sure he can play well with others.
The boxer generally behaves like a puppy throughout his life, which makes him quite problematic. Active, strong and loyal, it is a great pet for the whole family, both for adults and for children, but it can be lively, so it is not recommended in homes with very young children.
This dog has a stature which has no connection with his personality. Although it does not harm a fly, and with a bite force of 230 PSI, it will not waste time killing furry animals if it is not properly trained and socialized. He is friendly with family, dogs and children.
14. American Pit Bull Terrier
With all of the bad biases this dog has faced, you would expect this dog to have one of the best PSI scores of all dogs. But no, the American Pit Bull Terrier is not even at the top of the list, with a bite force calculated at 235 PSI. Like most animals, it will react if it feels threatened or stressed, but with early socialization, it is no more dangerous than any other dog.
13. German Shepherd Dog
We have all seen videos of this dog practicing police drills to split and hang on padded arms and legs until his master arrives. No wonder then that this incredible search and rescue dog has a bite force of 238 PSI, which means that when the German shepherd hangs on, he is there for the long haul.
It is important to understand that when specifying the grip strength, an average number is used, because in different parts of the jaw the pressure on the biting object will be different. The deepest puncture is made, of course, by the fangs, but above all the victim is squeezed by the canine molars; the incisors are less powerful, as they are farthest from the muscles responsible for closing the jaw. Example: the molars of an adult Rottweiler are compressed with a force of 1600 N, the incisors – 1400 N. It turns out that the average bite for this breed is 1500 N. For comparison: the force of compression of jaws of a leopard is 1070 N, a shark 4500 N, a wolf 1410 N, a bear 2000 N.
It’s no wonder the American Kennel Club has ranked this handsome boy among the 15 most popular dog breeds in North America. Its dramatic appearance and its soft and often shy disposition make it a family favorite who adores its human pack and with a bite force of 245 PSI, the doberman also makes an impressive and efficient watchdog.
Dobermans stand out among their relatives for their devotion and intelligence. Aggressive character is shown only in rare cases. Doberman attacks were reported when the owner or his property was in danger.
A rather strong appearance, combined with aggression, makes the representatives of this breed potentially dangerous to others, but with the right upbringing, they grow into excellent guards.
11. American Bulldog
The American Bulldog is a powerful and muscular dog is a loyal and loving family dog who, when properly socialized, gets along with everything he meets. No wonder, like its stocky and determined size, it has a strong bite that ensures that no tennis ball is safe when it is playing for research. His 305 PSI puts this dog in line with a leopard (300 to 310 PSI) in terms of bite force.
The pearly whites of the sociable Rottweiler offer more than just an engaging smile. This big boy can bite into a but – whether he snatches a treat in the air, struggles with a tug rope or confronts an intruder. Packing a full 328 PSI with each bite, this beautiful dog can be a loving pet or a pretty effective guard dog.
Of German origin, the leonberger is a beautiful dog, with long brown hairs. It is balanced, tall and muscular, able to measure up to 80 centimeters at the cross and reach a weight of up to 75 kg. He has a calm temper, but an imposing presence.

Its appearance is imposing and although its height at the cross is similar to that of the German shepherd, it is much more robust and muscular, even with a bite power of 540 PSI, the Perro de Presa Canario is a calm and balanced dog, very docile and loyal to its owner, although due to its strong watchdog instinct it can be aggressive with strangers and has often been included in the category of potentially dangerous dogs.
The mastiff is a breed of dog of molossoid type, with characteristics similar to the bulldog, and of large size even giant. It is an animal of great proportions, very striking in its physique, and with an enviable temperament. It is characterized by its strength and build, even as a puppy, and because it has been one of the companion breeds of human beings for a long time. Their bite force is enormous from the mastiff is 552 PSI.
The Mastiff is a balanced and calm dog, which, however, can break a person’s legs with its bite. Mastiffs were originally used for fighting, but it was soon noticed that the dog’s peaceful disposition was more suitable for performing guard functions. This ancient breed owes much of its strength to weight.
