Which Dog Has the Strongest Bite?
When it comes to determining the dog with the strongest bite, scientists measure the bite force in pounds per square inch (PSI). A higher PSI means a stronger bite, which is often influenced by the dog's size, skull structure, and jaw muscles. Understanding which dogs possess the most powerful bites can help clarify their capabilities, especially for working or protection purposes.
1. Kangal – The Champion of Canine Bite Force
The Kangal, a livestock guardian breed from Turkey, holds the record for the most powerful bite among dogs. With a staggering 743 PSI, this dog's bite is stronger than most wild predators and makes it the ultimate protector against larger threats.
- Purpose: Originally bred to guard livestock from wolves and bears
- Size: Males can weigh up to 145 pounds
- Temperament: Loyal, protective, and calm with proper training
2. Cane Corso – Italian Mastiff of Power
The Cane Corso boasts a bite force around 700 PSI. Strong, agile, and protective, this breed traces back to Roman war dogs.

4. Tosa Inu – The Japanese Warrior
The Tosa Inu is Japan’s canine gladiator, originally bred for dog fighting. Its bite force lies around 556 PSI.

5. Presa Canario – The Canarian Guardian

6. Rottweiler – The Versatile Protector
The Rottweiler combines strength and obedience with a bite force of roughly 328 PSI, making it effective for security tasks.
Why Bite Force Matters
A dog’s bite force can be an important consideration depending on your needs:
- Protection and Security: Strong-biting dogs are naturally more imposing and effective guard dogs.
- Livestock Guardian: Breeds like the Kangal are unparalleled in deterring large wild predators.
- Training and Handling: Stronger breeds need professional training and responsible ownership to prevent aggression.
Bite Force vs. Aggression
It’s crucial to understand that a high bite force does not make a dog naturally dangerous. Most large, strong dogs are calm and protective by nature. Aggression is more closely tied to socialization, training, and environment than physical strength.
Conclusion: The Mighty Kangal Reigns Supreme
While many dogs have powerful jaws, the Kangal remains the undisputed leader with its 743 PSI bite force. It is important for potential owners to recognize that with strength comes responsibility. Owning such a breed requires commitment and training to nurture its protective traits in a healthy and controlled manner.
