Top 15 Most Aggressive Dogs Breed in the World 2020

Dogs are loyal and yet sweet animals, and many people have them as part of their families. They are loving, loyal, and always ready to protect their human friends. However, there have been cases of dogs attacking humans, and some of these attacks have been fatal. Research shows that certain dog breeds are more aggressive and have caused more fatalities than others. But before we start judging these dogs, let us look at what really causes them to be aggressive.

Dog aggression is defined as dangerous behavior directed at another individual, including other animals. This behavior includes barking, biting, lunging, snarling, etc. The cause can range from territorial defensiveness and protectiveness to fear or social anxiety.

Fabulaes has pointed out Top 15 Most Aggressive Dogs Breed in the World. These dogs are included in the following list.


15. Great Dane

The Great Dane is a giant breed of dogs that make great family pets. They are gentle for their size and good with children. They do not need a lot of exercise like other giant dog breeds, but they need a lot of space.

Young Great Danes are highly energetic and can be very destructive and need supervision at all times. Great Danes vary in character. They never fail to announce when visitors come, but some are highly territorial while others are friendly with all people. The dogs will live peacefully with other dogs if properly socialized. Great Danes may use their size to try and dominate the house, and they need obedience training to keep them in check. They should also not be left unsupervised with children.

14. Tosa Inu

Tosa Inu is a large breed of dogs that was created in Japan. The breed is considered dangerous, but this is not all that true. Tosa Inus are calm, obedient dogs that would make great house pets since they do not mind being kept in the house. They were bred and used as war dogs, and some places in Japan still use them as fighting dogs, but they are not too violent to injure themselves during fights, and this makes the breed excellent guard dogs.

Despite their reputation as aggressive killer dogs, in reality, Tosa Inus are the opposite provided they have been socialized. They love to be around people and are even friendly towards strangers. They also never attack first, and they have a high tolerance for pain. They are calm and patient around children, although they should not be left unsupervised with kids.


13. Kangal

Kangals are a gentle breed of dogs that can be trusted around homes. They are calm around children and are protective of their owners. They also treat new people well and once they mark the territorial boundaries, they can recognize new people and animals.

Since Kangals are naturally territorial dogs, they tend to be dog-aggressive towards male dogs; especially those of dominant disposition. The Kangal should not be locked in a house or a small space as they will become destructive. Kangals are usually aloof towards new people until they get used to them. They are not dangerous but rather obedient and loyal, also they will not become aggressive towards people for no reason.


12. Perro de Presa Canario

This breed, also known as the Canary Mastiff, is a fearsome dog whose appearance can intimidate any person. They are bred as fighting dogs, and therefore, they are highly aggressive and can only be handled by experienced dog owners.

The Perro de Presa Canario are excellent guard dogs, but they can also be highly dangerous if nothing is done about the dog’s aggression. The dog needs attention and should spend a significant amount of time close to its family to prevent it from becoming destructive. Their aggressive nature has made the dogs to be banned in some countries.


11. Cane Corso

Cane Corsos are a giant breed of dogs that were bred as guard dogs and to hunt big animals. They take their responsibility as guard dogs very seriously and no matter how social it will always put its humans first.

Cane Corsos have a high prey drive, and if untrained they will chase and kill smaller pets. Due to their active nature, Cane Corsos should be allowed to exercise for a certain amount of time each day. They are also highly territorial and will act aggressively towards other male dogs. They have massive, powerful jaws that could cause severe damage to their victim.


10. Doberman Pinscher

The Doberman Pinscher is an obedient, energetic, intelligent, and alert; basically, all the good traits that a dog should have. It is a large dog with an impressive and fearsome stance. The breed was created for personal security, and so they are instinctively aggressive towards strangers who they may perceive as threats. The Doberman will also be aggressive towards other dogs.

Dobes, as they are sometimes called, need enough exercise to release energy and therefore they need enough exercise. The dogs also love being around people and therefore, they should not be left alone in the house as they will develop separation anxiety which will make them more aggressive. Dobermans that are social have most likely gone through proper training at a young age.


9. Wolf-dog Hybrid

A wolf-dog is a cross between a wolf and a domestic dog. There has been a lot of debate about whether wolf-dogs should be bred or not and some states have even made it illegal to keep them as pets. It is not easy to keep wolf-dogs as pets, more so around children, as some can be uncontrollably aggressive.

Wolf-dogs, especially those with a higher percentage of wolf genetics, lean more on their wild side and therefore they cannot be kept in the house as they will become destructive. As a result, wolf-dogs need vigorous training for them to interact well with people.


8. Alaskan Malamute

Alaskan Malamutes are sometimes confused with Siberian Huskies, but they are larger than the Huskies. They are usually seen as dangerous due to their big size. As with many other breeds, Alaskan Malamutes don’t like to be left alone but spend time with people, and they are very friendly to children.

Young malamutes are usually very playful and curious. Malamutes never attack first, and they are always careful around new people. But as expected from most dogs (as well malamutes) they can be aggressive towards other dogs, especially of the same sex, as they fight for dominance. However, proper socialization with other dogs will enable your malamute to get along well with them, and this should be done when they are still pups.


7. Husky

Huskies were bred to pull sleds on the snow and therefore they are quite energetic. This means that they need to be let out to get enough exercise; otherwise, they will become destructive. They also shouldn’t be left alone since they were bred to work with humans and in packs.

Huskies appreciate being in the company of humans, but they have a high prey drive towards small animals, and they cannot be trusted with them. Your Husky will go crazy and chase after a squirrel or any other small animals without heeding to your commands, and that is why they should be walked on a leash or let out to play in a fenced area. Huskies will live harmoniously with kids as long as the kids are not mean to them.


6. Mastiff 

This is another giant breed that originated from England. Mastiffs are usually gentle, but they can become aggressive due to various reasons. A mastiff’s behavior towards other dogs and cats will depend on how they have been raised. Those that are introduced to other animals at a young age will get along with them and not treat them as prey.

Mastiffs are naturally protective, and when they are trained to be watchdogs, they will rush to and corner an intruder until its master arrives. They, however, do not bite but rather growl at the intruder. This trait makes mastiffs excellent family dogs.


5. American Bulldog

This is a sturdy, muscular breed that makes great companions and protects its human friends. The breed has fighting roots which have caused many people to fear them. They also have a somewhat intimidating stance and ferocious barks which might scare people and get them thinking that they are a dangerous breed

American Bulldogs do not attack people. They might only bark when they see strangers, but they will not charge at them. The Bulldogs, however, are dog aggressive, and they will also ferociously chase cats. To prevent the Bulldogs’ aggressive behavior, they need to be introduced to other pets as puppies so that they can get along well and they should also interact with people more often to bring out their more friendly side.


4. German Shepherd

German shepherds are usually trained as guard dogs due to their naturally aggressive behaviors and tendencies. They not only possess strength and intelligence but are also loyal and overly protective of their human friends. These traits make German shepherds dangerous as they may attack strangers thinking that they are threats rather than friends.

German shepherds should not be kept in an enclosed space because this will cause them to build up too much energy with nowhere to release it. That is why they chew and destroy things when left alone in the house.


3. Rottweiler

Rottweilers are muscular dogs, and they need a large space for exercise. They are known to cause many fatalities in the US, but they aren’t as bad as they are made out to be. Rottweilers are naturally aggressive, but they are usually not dangerous to humans. They are intelligent and loyal dogs who usually study their environment before responding to situations.

Rottweilers are territorial animals, and they can be aggressive with other dogs. They also like being dominant and will test for dominance in their homes. Fortunately, Rottweilers are also good at obeying their masters and, therefore, with early and proper obedience training, you can control their territorial instinct.


2. American Staffordshire Terrier

Also known as the Amstaff, the American Staffordshire Terrier is a strong muscular breed of dogs. They are active and require daily exercise to maintain their muscle tone. This means that they need to be kept in homes with large yards for them to run around freely; otherwise, they will become destructive. American Staffordshire Terriers love to chew; therefore, it is advised that you provide your American Staffordshire Terrier with plenty of bones and chewable toys.

The American Staffordshire Terrier may develop aggression when it becomes neglected. It shouldn’t be left or tied up alone and instead it needs to be around the company of loving humans.


1. Pitbull

Someone may not want to believe it, but Pitbulls naturally have an aggressive temperament. They were initially bred to chase and catch animals and hold them down until their master arrived. Pitbulls start to develop their aggressive personalities around three years of age. Pitbulls are excellent fighting machines, and they are deadly in a confrontation.

They might be so aggressive that you cannot have other pets in the house. Because they are bred to be alphas, you should ensure that your Pit knows its place to prevent It from switching into alpha mode as it can become dangerous when it does. Pit bulls should, therefore, not be handled by an inexperienced person so as not to confirm the fears that they are dangerous dogs.
