How to Measure Dog Bites with PSI

A dog’s bite is measured with pounds per square inch (psi). Every unit of PSI shows the amount of force exerted on one square inch of space. Most dog breeds have an average bite strength of 230-250 psi. However, half of the breeds on this list exceed over 250 psi, with the Kangal breed holding the top spot of 743 psi

Measuring dog bites can depend on several components:

  • The substance being bitten
  • The dog’s behavior
  • The dog’s breed

Studies show that measuring a dog’s bite force can be done by using a transducer. This tool calculates their bite force using different dog sizes depending on their breed and mood. It’s revealed that bite force varies depending on a dog’s weight and independent from the head configuration and jaw adductor muscle mass.

What Dog Has the Strongest Bite Force?

A dog with a strong bite force can be trained to protect and serve their communities, but such training is dependent on the owner. All dog owners have a duty of care to train their pets not to be needlessly aggressive. If a dog is labeled an endangerment to the community, they may be put down according to your state’s dog bite laws.

Even though these dogs possess a deadly bite force, they all can be trained to be wonderful companions to entire households. Because of their size, dog owners must socialize and train these breeds to accept humans and other domesticated animals.

The Kangal takes the number one spot with the strongest bite force in the world. They’re loyal and reliable dogs trained to herd livestock and work well with children. They work better without existing dogs and can be timid if not socialized early.

They aren’t aggressive due to their gentle nature and strong instinct to protect, making them wonderful guardians of the house.

Does a Stronger Bite Mean a More Dangerous Dog?

A stronger bite doesn’t mean a more dangerous dog, as all dog bites can potentially be dangerous when left neglected. An owner can train their Kangal to behave with people and other dogs. An untrained Chihuahua, however, can still inflict dangerous injuries to other humans.

Never provoke a dog with a bite force that can puncture and break human bones. Provoking a dog may raise your liability or even disqualify you from further compensation.

Effects of a Strong Dog Bite

Minor dog bites may leave no skin marks, but take pictures to prove your pain and suffering. Your attorney needs as much evidence as possible to represent your dog bite claim. Nevertheless, dog bites that lead to severe damages may cause:

  • Breakage or tearing of the skin
  • Puncture wounds
  • Damaged bones

The effects can then lead to:

  • Redness and swelling around the wound
  • Feeling of warmth and increasing pain
  • Liquid/pus leaking from the wound
  • Fever/Chills
  • Swollen glands beneath the chin, neck, armpits, or groin
  • Red streaks extending along the skin
