1. Tibetan Mastiff: It is the only breed of dog not afraid of wild animals, an adult Tibetan Mastiff can confront three wolves, known as the “king of the dogs” to fight with wolves, leopards, lions, etc. and famous in the Colosseum. 2. Caucasian: It is a giant dog, up to 90 cm, can defeat a poaching wolf alone; 3. Twisted Boliverton Dog: It is a notorious corpse-eating dog, a favorite of the mafia, which likes to eat defeated enemies or prey. 4. The most ferocious point of the Pitbull is that it can hardly feel pain when fighting, mainly because of its adrenaline rush, plus its weaker subcutaneous nerve perception, which results in an extremely frantic performance when fighting.
