A study conducted by researchers at the University of Guelph in Canada revealed that different dog breeds have significantly different biting forces. The research analyzed the pressure exerted by the jaws of various dogs and revealed which ones have the most powerful bites.
For comparison, the average human bite force is around 162 psi (pounds per square inch). However, some dog breeds surpass this number several times. Check out the five dog breeds with the strongest bites in the world, according to the study.
5. Rottweiler

The Rottweiler is a powerful breed, known for its loyalty and protective instincts. Its jaws can exert a force of 328 psi, making it one of the dogs with the most potent bites. Despite its strength, the Rottweiler is usually calm and balanced, making it suitable for experienced owners who know how to train it properly.
4. Leonberger

The Leonberger, known for its majestic appearance and gentle temperament, has a bite that can reach 399 psi. However, this large, furry dog tends to use its strength mainly to chew toys, sticks, or occasionally its owner’s shoes.
3. Mastiff

The Mastiff is one of the most imposing dog breeds in the world, and its bite reaches 552 psi. Historically, these dogs were used to protect villages and even hunt wolves. Today, however, they are primarily bred as companion dogs, maintaining their gentle temperament despite the incredible power of their jaws.
2. Dogue de Bordeaux

With a bite of 556 psi, the Dogue de Bordeaux takes the second position in the ranking. Despite this impressive strength, the breed is known for its calm and lazy nature and is unlikely to use its biting power frequently.
1. Kangal – The Bite Force Champion

The title of the breed with the strongest bite in the world belongs to the Kangal, which reaches an impressive 743 psi. Originally bred in Turkey, the Kangal is an excellent guard dog, protecting livestock from predators. Despite its raw strength, the Kangal can be a great family dog when properly trained, known for its loyalty and affection towards children.
A dog’s bite force does not determine its aggression but rather its physical capacity. When these breeds are well-trained and socialized, they can make great companions and perform essential roles, from protection to harmonious living in families.
