Curious to discover the biting force of a pitbull?

Pitbulls (and other similar dog breeds) are dogs often associated with aggression, power, and strength. The breed was originally bred for dog fighting, so breeders would breed ferocious pitbulls and related dog breeds known for their aggressive tendencies.

In this guide, we will tell you exactly how much damage a pitbull dog breed and their bites can inflict. 

How Much is a Pit Bull Bite Force?

According to Dog Bite Attack Lawyers, pitbulls are capable of exerting a force of 235 psi. PSI stands for pounds per square inch. In the case of certain dog breed bites, the PSI rate is calculated after considering the weight of the dog breed, the size of the dog’s jaws, and the angle at which the dog bites.

Please note that the pitbull consists of various dog breeds like the American Pit Bull Terrier, American Staffordshire Terrier, American Bully, Staffordshire Bull Terrier, and also the American Bulldog.

These are the breeds with the strongest bites. Although they can be sweet dogs, the dog owner needs to be experienced in handling dogs. After all, these were trained to be attack dogs, and fighting dogs and their dog bite can be dangerous.

Since the pitbull dog breed consists of large, heavy dogs weighing almost 55 to 70 pounds (25 to 32 kilos), they are capable of exerting a lot of bite force when they bite an individual. Their muscular build and powerful jaws further exacerbate this bite force. Imagine this bite force on a child or elderly person! The bite force is enough to cause limb loss, disfigurement, and permanent damage.

No wonder pitbulls are stereotyped as dangerous dogs. The American kennel club does not recognize this particular breed. However, we must remember that this breed of dog is inherently loyal and affectionate. With the right environment, training, and socialization, we can prevent pitbull attacks.

Can a Pitbull Bite Break Bones?

Yes, experts have seen several cases where pitbull bite force has broken human bones. The 235 psi rating indicates that a pitbull can easily tear or puncture the skin and crush bones in multiple places. Furthermore, these heavy dogs can easily make a human being fall down, which can further result in fractures.

Dog Bites – What Happens If a PitBull Bites You?

If a pitbull bites you, you could suffer serious injuries that can be life-threatening. Depending on the angle of the bite force and the dog’s weight, as well as the intention behind the bite, a pitbull could tear or puncture the skin. The bite force could also crush the bones and cause severe fractures.

If the bite is not too deep, please wash it with some warm water and antibacterial soap. If it is bleeding, please seek medical attention immediately.

After cleaning the wound, keep the bite site elevated to stop the bleeding. If needed, wrap a clean bandage around the bite along with some antibiotic cream.

If the pitbull is not vaccinated, you may want to get the anti-rabies vaccine. You’d also need the tetanus vaccine to prevent the life-threatening infection.

How is a Dog’s Bite Force Calculated?

Several factors influence a dog’s bite force. As mentioned before, the dog’s weight, size of the jaws, and overall muscularity impact the pressure or the bite force it can exert. 

The skull structure and size and shape of the dog’s teeth can also impact bite force. Similarly, one needs to account for the angle and bite style when calculating the dog’s bite force.

Bite force calculation also involves taking the surface hardness of the individual/object being bitten into account. 

We must also understand that measuring a dog’s bite force accurately may involve sedating the dog and hiding sensors in its cheeks. All these measures cannot take into account the psychological factor of motivation behind biting. This, too, can impact the psi of the bite force.
