10 Dangerous Dog Breeds

Related Articles

There are approximately 1-2 million known species of animals in this world. Some of them are dangerous predators, while others are cute, fluffy and harmless, such as domesticated cats and dogs. Dogs have been men’s best friends for decades. Most dogs are bred with the desire to please their masters. However, it can’t be helped that some dog breeds have more potential to inflict serious harm if the dog were to decide to attack. Most of these cases involve improper training, lack of socialization, cruelty and abuse. Here I have listed ten dangerous dog breeds with the most potential to cause serious injury.

Number 10: Rottweiler

Rottweiler dog

Rottweilers rank as one of the most ancient breeds and were originally bred to drive cattle to market. They were among the earliest police dogs and served with honor in the military. Rottweilers are blocky dogs with massive heads. They are considered medium to large in size and can weigh up to 130 pounds. Most of these weights are pure muscle!

They have an impressively strong bite, with a bite force of around 300 pounds per square inch. Rottweilers are considered dangerous because they have a genetic predisposition to guard and hurt. However, with proper training, not all are savage beasts! As with many breeds, these dogs have a bad reputation due to abuse, neglect, lack of socialization and lack of training. 

Number 9: Boerboel

Boerboel dog

Boerboels are considered to be the most agile of the Mastiffs, the most ancient types of dog breeds. They are large domesticated working dogs, originally bred to help South African farmers defend their homesteads from all manners of deadly wildlife, such as hyenas and lions.

The usual Mastiff bites are around 500 pounds, while the Boerboels’ are over 600 pounds. Muscular, exceedingly robust and loyal to a fault, these large and ferocious guard dogs can show aggression when feeling uneasy and would defend their family bravely, even to the death. For this reason, it is vital for strong discipline to be introduced early and maintained for the Boerboel puppy. With appropriate training, they can be loving, calm and family-friendly, especially towards children. 

Number 8: Dogo Argentino

Dogo Argentino dog

These Argentinian Mastiffs are pack-hunting dogs, originally bred for the pursuit of big-game such as wild boar and puma. They possess the strength, intelligence and quick responsiveness of a serious athlete and are known for their incredibly muscular bodies, with massive skulls and strong jaws.

Dogo Argentinos are not so dangerous towards human but can be lethal to smaller dogs and animals due to their strong urge to hunt their prey. They are often trained for police work, search and rescue, military work, and as service dogs. With proper training, i.e. early socialization with other animals and early obedience training, they can make an excellent family companion and watchdog. 

Number 7: Perro de Presa Canario

Perro de Presa Canario dog

The Presa Canario is a large-sized dog breed, Molosser-type, also known as the Canary Mastiff. They are powerful, intelligent and headstrong, originally bred for working livestock on the island of Gran Canaria. These natural guard dogs are highly suspicious of strangers and protective of their territory, and will sometimes act aggressively towards people or animals they don’t know.

Presa Canarios are complex, powerful and remarkably well-muscled dogs, capable of causing serious injuries. However, with experienced owners and appropriate training, they can be great family protectors, companions as well as guardians.

Number 6: Caucasian Shepherd

Caucasian Shepherd dog

The Caucasian Shepherd is a working dog breed that originated from the Russian Caucasus Mountains as a livestock guardian dog. They can be fearless, self-confident, and fierce when they detect a threat.

Caucasian Shepherds are large, strong, with plenty of bone and a powerful muscular system. They are highly territorial and won’t back down from a fight, even against bears or wolves. With these protective instincts, Caucasian Shepherds have been known to save lives as well as causing serious injuries. 

Number 5: Tosa Inu 

Tosa Inu dog

The Tosa Inu is a large breed of dog that originated in Japan in the 18th century. Bred and developed to be a massive quiet dog-fighting machine, as Japanese dog fighting rules called for silence, this natural guard dog is protective, courageous and fearless. The Tosa Inu is often described as being stately, quiet, calm and relaxed, until aroused. With a weight up to 200 pounds and a bite force over 500 pounds, Tosas are known to have the potential of pulling more than 3000 pounds in weight!

This breed is considered dangerous in many countries, including the United Kingdom and Australia. Despite public perception, the Tosa Inu has the potential to be a loyal and dependable dog as long as it has proper training and guidance from its owner.

Number 4: Pitbull 

Pitbull dog

The Pitbull is a breed that faces a lot of unfair discrimination, with plenty of stigmas, untruths and confusion associated with them. Because of their strength and muscular build, Pitbulls have been bred for fighting or kept by irresponsible owners as a status symbol.

This, along with media bias, has resulted in them developing an unfair reputation for being overly aggressive. The truth is, in the right home, Pitbulls are usually incredibly loving, loyal and gentle with their family members. They are especially fond of children, showing a high degree of care and protection. 

Number 3: Chow Chow

Chow Chow dog

The Chow Chow is perhaps the most ancient of the Chinese breeds of dogs. They are an all-purpose dog and have been known as sled pullers, hunters, livestock guarders and, unfortunately for them, dinner. Chow Chows are powerful and compactly built, with a distinctive appearance of a lion’s-mane ruff and a pair of deep-set almond eyes that add to a scowling snobbish expression.

Chow Chows are not usually socially outgoing dogs but are devoted to and protective of their families. They tend to be aloof with strangers and can be aggressive with other dogs. With a powerful bite force of 220 pounds per square inch, Chow Chows can be dangerous if not properly trained. 

Number 2: Fila Brasileiro

Fila Brasileiro dog

The Fila Brasileiro was developed to be a hunting dog working on ranches and plantations in Brazil. They were used to guard the estate against thieves, hunt big game animals, help wrangle cattle and hunt down escapees during slavery times. The Fila would grab its prey by the neck and hold it until its owner arrives.

This Brazilian Mastiff is a large working breed known for its superb tracking ability, aggressiveness and an unforgiving impetuous temperament. They are affectionate and docile with their family, even children, but instinctively possessive and territorial and doesn’t take kindly to strangers. Poorly trained Fila Brasileiro dogs can become very unpredictable and dangerous. 

Number 1: Wolf-Dog Hybrid 

Wolf-Dog Hybrid dog

Wolf-dog hybrid is a term used to describe an animal that is part wolf and part domestic dog. Many states/countries have already banned the possibility of owning a wolf hybrid as a house pet because of their unpredictable nature. The diversity of genetic composition, even within one litter of hybrid pups, leads to a wide range of appearances and behavior patterns. Wolves and wolf hybrids have a significantly different temperament and social pattern than domestic dogs. They can be territorial and aggressive, with a bite force over 400 pounds per square inch and a formidable speed and stamina. Improper socialization and training make them even more dangerous.
