What Is the bite force of a Neapolitan Mastiff?

The Neapolitan Mastiff is an enormous, ancient dog breed that originated in the Italian city of Naples. This massive dog is both muscular and wrinkly. The Neapolitan Mastiff has the strongest bite of any breed at 552 pounds of pressure per square inch (PSI)

These dogs were bred to be extremely protective of their family and property. The Neapolitan Mastiff has become popular today as a companion and working dog.

Bite forces of some other dogs

Dogo Argentino

The Dogo Argentino possesses a bite force of 500 PSI. This dog is a hunting dog that was developed in Argentina primarily for big-game hunting, including wild boar and puma; the breeder/owner of this breed, Antonio Nores Martinez, also wanted a dog that would exhibit loyal bravery and willingly safeguard its human companion to the death.

German Shepherds

German Shepherds have a bite force of 238 PSI, which is on par with other large dog breeds. The bite force of a German Shepherd is not as much as that of bigger dogs like mastiffs and rottweilers, but it’s still more than enough to cause some serious damage if they ever attack you. Their jaws are strong enough to clamp down and crush bones with ease. This makes them one of the most menacing dog breeds in the world.

American Pitbulls

American Pitbulls have a bite force of 235 PSI, which puts them in the same range as German Shepherds. They were bred for “the sport” of dog fighting, and their jaws are just as deadly as their reputation suggests.

The Rottweiler

A Rottweiler has a bite force of 328 pounds per square inch. Rottweilers originated in Germany and were bred to drive cattle to market and pull carts for butchers. They were among the first dogs used by police officers and are also popular with the military, which uses them as guard and attack dogs. Now, Rottweilers are best known for their sweet temperaments, which makes them wonderful family pets. The breed needs regular exercise, but it can do well in an apartment if it gets enough attention.

The American Bulldog

The American Bulldog has a bite force of 305 PSI. The American Bulldog is a breed of utility dog originated from the Old English Bulldog. Today, these dogs are used in the farming industry and as working dogs for hunters. They are very muscular, loyal to their owners, and have a good temperament with children.

Factors affecting the bite force of a Neapolitan Mastiff

Bite force is the force which an animal can exert through its teeth, and is measured in Newtons. The Neapolitan Mastiff has a fairly strong bite force for its size, but there are a few factors that can affect it.

Body size

A larger dog will have more muscle to apply behind its jaw. This means that bigger dogs have a stronger bite. Obviously, this also means that smaller dogs usually have less biting power than larger ones.

Skull shape

A mastiff with a shorter snout will apply more force on each individual tooth. Dogs with longer snouts spread the biting pressure over more teeth, meaning they apply less pressure on each tooth.

Mouth shape

A dog with smaller teeth will apply more pressure per tooth because they are closer together. Wide mouthed dogs spread their biting pressure over more teeth, meaning they don’t apply as much pressure on each tooth.

Muscle density

The muscles around the jaw of a Neapolitan Mastiff play an important role in how much pressure they can apply when they bite down. Dogs with denser muscle structure will generate greater force.

Mouth structure

The size and shape of the mouth also plays an important role in bite strength. A wider mouth means more surface area for the teeth, which means more teeth to dig into something. It also means that the jaw can exert more outward pressure and create a greater crush effect on whatever is between the teeth.

Your dog’s personality

Some dogs are just more aggressive than others. If your dog seems to be especially aggressive, or if they’re quick to bite when they feel threatened, there’s a good chance they’ll try to bite you at some point.

How well trained your dog is

A well-trained dog will know when it’s time to stop biting and let go. A poorly trained dog may not understand that biting hurts people, which leads them back into trouble again soon after being released from.

The environment

Some dogs will only attack in certain situations such as when they’re guarding a resource like food or their home territory. It’s important that you take steps to prevent this kind of situation from happening. For example, don’t leave food out where your dog can get to it easily if you have visitors over.

How to stop a Neapolitan Mastiff dog from biting?

The Neapolitan Mastiff is a large, ancient dog breed. We often use this massive breed as a guard and defender of family and property because of their protective instincts and their fearsome appearance. Owners of the Neapolitan Mastiff must be prepared to handle a large, muscular dog with a propensity for aggression toward other dogs.


1. Stop the puppy as soon as he bites. Do not encourage biting by playing tug-of-war or any other roughhousing games with the pup. Always say “no” firmly when he sinks his teeth into you, your clothing or an inanimate object. This teaches him that biting is unacceptable behavior.

2. Use distraction to stop biting when the puppy will not stop. To distract him from biting, shake a can filled with pennies or throw a small blanket over him so he cannot see you for a few seconds. This will make him stop whatever he is doing and look at you in confusion. Immediately praise him for stopping the biting behavior with soothing words and petting so he realizes he did something you like.

3. Give the Neapolitan Mastiff an outlet for his energy by walking him for at least 30 minutes every day so he can run around, play and burn off energy, rather than using it to bite people or objects around the house. Exercise will also help.

4. Socialization will help your pet become accustomed to new people and situations. Start socializing with him as soon as you bring him home. Take him for walks in your neighborhood so he can get used to seeing other people and animals. Make sure the experiences are positive ones by giving him treats when he’s good around new people or animals. Never take him out for a walk when you’re angry or upset because your mood will rub off on him, and he’ll associate the new experience with negative feelings instead of positive ones.

5. Take the Neapolitan Mastiff to puppy classes where he can be exposed to other dogs and people while learning basic commands, such as sit, stay, and come. Continue training throughout his life so he knows what’s expected of him at all times. Consistency is key in training a Neo because of his alpha personality type.


The bite force of a Neapolitan Mastiff is 552 PSI (pounds per square inch). The pressure exerted by the dog’s mouth when it bites can vary depending on many factors. The different factors include dog breed, size, and age of the dog. An adult dog usually has a stronger bite than a puppy. We measure the bite force of dogs in pounds per square inch (PSI). Usually, the larger the dog, the more powerful its bite. Dogs that are bred for hunting or fighting usually have strong jaws and sharp teeth.

The PSI of a Neapolitan Mastiff is one of the highest among giant breeds. This is because this dog was originally bred for hunting and fighting. They were also used as guard dogs and protectors for livestock and property. The Neapolitan Mastiff has been used in war by both sides in ancient times, and as a result, there are many myths about them being ferocious beasts with an uncontrollable bloodlust.
