1. Rottweiler

There are three major dogs in the world that will never bite, and there are ten most vicious dogs in the world. Although ranked at the bottom, Rottweiler dogs are also very aggressive. With fast movements and fierce momentum, the Rottweiler was born with the talent of a guard dog. In southern Europe and ancient Rome, the Rottweiler was a dog used to hunt livestock and slaves. The bite force is one of the strongest in the world. With just a little force, your hand will be bitten with a big bloody hole. The Rottweiler has a strong ability to tolerate stimulation and has a long-lasting ability to fight in confrontations and bites. It’s best to stay away from people who have Rottweilers and don’t make mistakes easily. 2. Boliton

It was originally an ancient Roman fighting dog. Wherever Boliton appears, there will be a line of eye-catching big words "Attention, danger!". The muscles all over his body are tight and elastic, and under his huge head is an elongated face full of wrinkles, resembling a serious and unsmiling math teacher in high school. As one of the most powerful fighting dogs in the world, he is cold and silent. The Italian Mafia uses it as a companion dog to show terror and power. For people or prey that you kill, you can just eat them on the spot. There is no kindness at all. It has a cold and eccentric personality and is not easy to train. Once successfully tamed, it is a sharp killing weapon. 3. Cane Corso

Cane Corso is not easy to control. Although some people are raising Cane Corso now, even people who meet and feed it every day will be bitten by Cane Corso. It can be said that the index of aggression towards strangers is at full level. As Cane Corso dogs that once served in the ancient Roman army, they can accompany their owners on the battlefield to kill enemies and plunder, which is enough to see how violent they are. By nature, they are very defensive, especially the male Castro, who has strong dominance over his master and territory. If you can't control it well, don't keep it. All the attacks of Castro will not be groundless, so it is best for owners who do not have time to train and manage them to give up breeding from the beginning. 4. Bull Terrier

The Bull Terrier looks like a rabbit, and its eyes are beady. It looks very funny, but you won’t find it funny when the Bull Terrier bites people. They are naturally very excited and have inexhaustible energy. In battles with dogs, they will never admit defeat except to fall down, and may even violently harm other dog breeds. After a certain amount of artificial training, it can become a better family guard dog, but it is very difficult. Bull Terriers are artificially bred and have a genetic disease of deafness. Congenital deafness makes it difficult for them to hear commands, and they can't even hear their owners' scoldings when they bite like crazy. Another point is the nerve problem. The nerves are large and pulsating. It is not uncommon for sleepwalking and biting people to occur while sleeping. 5. Tibetan Mastiff

The Tibetan Mastiff is a dog breed native to my country. The high altitude and low temperature of the Qinghai-Tibet Plateau have created the characteristics of the Tibetan Mastiff, which are cold, decisive, powerful, sturdy and aggressive. Although it is recognized as the oldest and only rare breed of dog in the world, it does not stop the news of Tibetan Mastiffs from injuring people appearing frequently. Everyone knows that Tibetan Mastiffs only recognize one master in their life. In other words, in the world of Tibetan Mastiffs, there is only a distinction between "owner" and "stranger". Tibetan Mastiffs are always extremely wary of strangers. Even if they hug their owners in a friendly way, the Tibetan Mastiffs will pounce on you and bite you if they think it is an intrusion. Tibetan mastiffs are rarely seen in the city. 6. Dogo Dog

The Dogo dog ranking fifth is really not just talk. Its genes contain the genes of six vicious dogs. Originally bred to hunt leopards and lions, they are extremely aggressive. Dugo's favorite move is to choke. As long as he locks his target, he will run wildly and bite the enemy's throat. The Dugao murder in Zunyi, Guizhou in May 2013 was a real incident of vicious dog injuries. One of the two Dogos was watching the wind on the roadside, and the other dragged an old man doing morning exercises into a ditch beside the road and bit his throat. In the end, the old man died before being treated by medical staff. There are many videos of Dogo in a chokehold on the Internet. Just take a look and don’t be curious to find Dogo to play with.

7. Brazilian File

The Brazilian File is a hunting dog with strong tracking ability. It is on the list of banned dog breeds in many countries of the United Nations. During the ancient slavery period, Basil Feile was the lackey of slave owners who persecuted slaves. Just one adult Philae can knock down a 1.8-meter strong man. The more interesting point is that when it finds prey or slaves, it does not attack, but traps the prey until its master arrives. But that doesn't mean it won't attack. If the prey cannot be controlled by the owner before the owner arrives, the brazil will directly bite the prey with its mouth and bite the prey in an unorganized manner until the prey dies.
