Bite force varies widely among breeds, but temperament and training play a bigger role in a dog's behavior. Strong breeds like the Kangal and Cane Corso need experienced handling, while others like the Greyhound and Newfoundland are gentle despite their power. Responsible ownership—proper training, socialization, and exercise—ensures a well-balanced dog regardless of bite strength.

A dog bite can result in serious injuries, medical expenses, and legal complications—especially if the dog has a high bite force (measured in PSI). The stronger the dog's bite, the more severe the potential damage, increasing the likelihood of lawsuits, insurance claims, or even criminal liability for the owner. If you or a loved one has been bitten by a dog with a powerful bite (such as a Kangal, Mastiff, or Rottweiler), seeking legal counsel is crucial. A lawyer can help determine liability, negotiate with insurance companies, and ensure you receive fair compensation for medical bills, lost wages, and pain and suffering.

How Bite Force PSI Impacts Legal Cases

In dog bite lawsuits, the breed's bite force (PSI) may be used as evidence to demonstrate the severity of the attack. Dogs with exceptionally high PSI ratings (over 300-700 PSI) can cause bone fractures, nerve damage, and permanent scarring, which can lead to higher settlement demands or punitive damages. Additionally, certain breeds with strong bites may be subject to breed-specific legislation (BSL), meaning owners could face stricter liability. A skilled attorney will analyze the dog's breed, bite history, and local laws to build a strong case.
