10 Most Dangerous Dog Breeds In The World

Is a dog man’s best friend? You would think that all dogs are like that, but that is not the case! Researchers and critics don’t always agree on what makes these dogs dangerous. The criteria for declaring an animal dangerous is not unanimously agreed upon. There is a similar disagreement among dog lovers on the issue that these dogs cannot be tagged as dangerous by random and banned in some countries. It cannot be ignored, however, that some breeds of dogs can be dangerous to their human counterparts. They are highly aggressive and can cause serious injury to humans. Despite the fact that dogs are primarily bred to protect their masters and bring unconditional love to their families, some of these breeds turn out to be incredibly dangerous when they are unchecked. In short, the reasons do not lie with the breed or the dogs themselves, but rather with their owners and the way they are treated. According to research, some dogs have been bred to attack strangers when they are in their sight regardless of who they are. These creatures grow up as ferocious creatures without any sense of discernment, as a result of harsh treatment. Dogs often attack innocent people as a result of being trained to harm and from inhuman ownership attitudes. However, some dog breeds are inherently more lethal than others, regardless of the logical reasons for the attack. Here are ten of the most dangerous dog breeds in the world.

10 Most Dangerous Dog Breeds In The World


There is little difference between these dogs and wild wolves. Simply because of the nature of their names, they are likely to evoke danger signals in the mind! Dogs and wolves are basically crossbred, hence the name. In this breed, the ability to prey heavily on small prey animals or pets is retained, so they are hazardous to children and other small pets. Animals that seem relatively helpless to Wolfdogs are likely to be attacked by them. Their aggressiveness varies according to the hybrid. Breeding a German Shepherd with a Wolfdog, for example, would result in a less predictable and more dangerous dog. Wolfdogs are intelligent and powerful dogs weighing about 55 kilos.

Cane Corso

This large breed is an ancestor of the Italian Mastiff and was bred by the Romans as war dogs. It weighs 50 kilos, about 110 pounds. Its head is its most intimidating part. It is muscular, yet sleek. Even the bravest of men will run for their lives when they see its powerful open jaws! Cane Corsos, despite their good temperaments, are extremely protective of their masters, which makes them exceptionally wary of strangers. Because of this, they should be socialised early to prevent them from being dangerous. The breed is not allowed in several European countries and states in the US.

Neapolitan Mastiff

Even the most benevolent dog lover will be intimidated by the Neapolitan mastiff’s weight of nearly ninety kilos, which is two hundred pounds. Do you remember “Fang” from Harry Potter? The dog in question was a potentially dangerous Neapolitan Mastiff. They are thought to derive from the bloodthirsty war dogs of ancient Rome, namely the Roman Molossus – dogs trained to kill and maim opponents during wars and bloody battles in the arena. This breed is still widely used as guard dogs.

Dogo Argentino

Dogo Argentinos are smaller than mastiffs, but they are more muscular and agile. The dogs were bred to be companions to the game hunters, who taught them how to kill wild boars and pumas. Dogos weigh sixty kilos and have short coats mostly white, and are a cross between the Great Dane and Cordoba Fighting Dog. Despite being bred for family pets, this breed has been restricted in Australia and the UK because it has a reputation for being extremely aggressive and capable of lethal results when attacked!


It is hard to overstate just how infamous Rottweilers are! One of the most feared dog breeds, this breed has a stocky and powerful build. Since it was used for pulling carts and minding livestock, the Rottweiller dog was called the butcher’s dog in many countries. Despite the competition offered by several exotic breeds of killer dogs in the past few years, Rottweilers remain one of the most feared of all dogs; amply supported by statistics. Rottweilers are responsible for every other dog attack in the United States.

Caucasian Ovcharka

There are several names for this humongous dog, including Caucasian Shepherd Dog. This dog weighed anywhere between 90 kilos and some more and was designed to protect sheep from thieves along the Soviet Union’s borders. The jaws of this animal are as intimidating as its large paws! His fur is thick and he has powerful muscles. When West Germany and East Germany were at war, the Caucasian Ovcharka was widely used to patrol the borders. These dogs are favorites of dog fighters and will do anything to protect their master from harm.

Presa Canario

Presa Canario is a breed that should only be handled by experienced handlers. When threatened, its powerful head, muscular body, and large bony structure will send shivers down any human’s spine. If the master does not have absolute control over the dog, it can become extremely aggressive and have fatal consequences. Despite being bred domestically, they retain their traits as pack dogs. They are frequently reported to attack. Their breed is illegal in many countries like the United States.

Fila Brasileiro

As a hunting dog, the fila brasileiro (also known as the Brazilian Mastiff) is powerful and muscular, just shy of 75 pounds. Their training included returning runaway slaves to their masters without harm! Filas have become popular as guard dogs, but they are banned in Norway, Denmark, the UK, and Israel for their high potential for harm. The Fila is sometimes referred to as an Ojeriza. It is known for its aggressive and unpredictable nature, which is why it is appealing to owners, but highly dangerous to others.

Pit Bull

Pit Bulls are another notorious breed of dog, along with the Rottweiler, for their high fatality rate, reported in the media on a frequent basis. Pit Bulls are one of the most dangerous breeds of dog. They distinguish themselves from other breeds by their ferocity, stocky muscular bodies, and square-like heads. Compared to other dangerous dogs, these are smaller and weigh about 40 kilos. Originally, they were bred for fighting only. There is no single definition of a Pit Bull; it is more of an umbrella term given to a family of dogs with similar physical characteristics.

Tosa Inu

Dogs such as the Japanese Tosa Inu, which can weigh up to 100 kilos, are bred as fighting dogs as well. This breed is also known as the Sumo Mastiff. It’s surprising to find that this breed has been raised and crossbred more in the US and UK than Japan. Crossbreeds have included Bull Terriors, Great Danes, St Bernards, Bulldogs and even Mastiffs. This breed is normally calm, but if handled harshly and trained inappropriately, it is potentially very dangerous.


Be Careful When You Encounter Aggressive Dogs

Despite being with man since time immemorial, some breeds of dogs are renowned friends, especially those that are domesticated from wild wolves. Despite the fact that the man-dog relationship is immensely beneficial for both parties, in many countries these breeds are illegal and dangerous. However, the media and authorities recently became aware of the chilling accounts of fatal attacks on humans by some of these breeds kept as pets.

These animals attack unsuspecting children and adults in public parks and neighborhoods on a regular basis, causing the alarm of hundreds of animal lovers who advocate legislation prohibiting owners from keeping such dangerous breeds that prove dangerous to people around them. According to a survey conducted in the UK, hospitalizations due to dog attacks alone have increased by more than 300% in the past twenty years.
