While “man’s best friend” has been living as a domesticated animal for some time, over time certain breeds have emerged as more aggressive than others. Some dogs have been bred for fighting because of their personality, anatomy, or size and over time these dogs have evolved into fighting machines. From dogs bred to kill lions, to dogs with wolf-blood in their veins, here are the 25 most aggressive breeds in the world.
25. Tosa Inu
This dog is one of the larger breeds on our list; a full-grown male can weigh up to 200 pounds and be as tall as 32 inches. The Tosa Inu was bred as a fighting dog, and continues to be used as a guard dog because of its aggressive nature and size. In fact, owning one is actually restricted by law in some countries because of its aggressive nature.
24. American Bandogge
Known for its brute strength, this dog came about when a breeder decided to cross a Neapolitan Mastiff and an American Pitbull terrier. This dog’s muscled body and strong jaw have made it a favorite fighting dog.
23. Cane Corso
This dog is the modern descendant of dogs bred by the ancient Romans as a fighting dog. To disorient and confuse their enemies, they would unleash packs of these dogs that had been trained especially for war. It’s no wonder that this dog, which can reach 150 lbs, found its way onto our list.
22. Bull Terrier
This dog’s signature head makes it immediately recognizable. This terrier, though one of the smaller dogs on our list, has one of the greatest muscle-to-bodyweight ratio, making it a dangerous breed for anyone that it decides to attack.
21. Rhodesian Ridgeback
This dog was bred as a lion-hunting dog. It was trained to distract a menacing lion while its owner would prepare the fatal shot for the giant cat. While these dogs are very intelligent, they can also have an overdeveloped sense of protectiveness which can make them dangerous to strangers
