15 Dog Breeds Known for Their Aggressive Behavior

Most pet owners and enthusiasts find it difficult to imagine their dogs behaving aggressively towards them. While many breeds are friendly, some have reputations for being aggressive and potentially dangerous. Understanding these breeds can help ensure both your safety and theirs. Here is a list of 15 breeds that are commonly perceived as aggressive.
Pit Bull Terrier

It is widely recognized as one of the most potential wild dog breeds in the United States and worldwide. These dogs are mighty and can overpower anyone who tries to oppose them. Pitbull enthusiasts argue that it is unjust to label these dogs as aggressive. While there are controversies surrounding the classification of pit bulls as aggressive, it is undeniable that their strength and jaw size pose a potential threat to humans.
Chow Chow

The Chow Chow, originally from China, is a 50—to 70 lb dog breed known as Songshi Quan or ‘puffy-lion dog.’ They possess excellent discernment abilities when identifying strangers and can be incredibly protective of their owners. This breed isn’t typically fond of strangers, which makes it a risky choice for families with young children.
Akita

Being naturally cautious around strangers and other dogs, Akitas may display hostile behavior. If an Akita bites someone, it has the potential to be fatal or to dramatically alter the victim’s life because their jaws cannot be opened unless they choose to let go. Early socialization and firm training are crucial to managing their dominant tendencies. When well-trained, they are incredibly devoted and loving companions.
Rottweiler

They are robust and formidable dogs with powerful bites capable of inflicting severe injuries or even death. Moreover, their aggressive and territorial behavior poses a significant danger to humans and other animals. Adoption and ownership of these canines are prohibited by law in Poland, Portugal, and Ireland. The German breed is known for being protective, loyal, and watchful, but this can lead to aggression toward outsiders.
Doberman Pinscher

The Doberman Pinscher can be a formidable dog to own or encounter unexpectedly. Think of it as a surprise encounter with a grizzly bear in the depths of a remote forest. In addition, it is worth mentioning that this dog’s bite is regarded as the most powerful bite ever recorded. Positive reinforcement can help this breed become social and develop a protective yet welcoming nature.
Siberian Husky

Siberian Huskies were initially bred as diligent work companions, which is why they tend to be less inclined towards interaction. With the correct approach and proper training, you can transform them into friendly and calm companions. If they are not properly socialized and trained, they risk becoming aggressive and potentially dangerous animals!
German Shepherd

Not only are German Shepherds among the most well-liked dog breeds globally, but they also rank among the most dangerous. The dogs are frequently utilized as police dogs, guard dogs, and service animals. Originally, they were bred to herd and protect sheep. A person could bleed to death from a German Shepherd’s bite if it were strong enough to shatter a bone or burst a blood artery.
Alaskan Malamute

Large dogs like the Alaskan Malamute were first bred for use in the Arctic for labor and hunting. They are robust, aggressive, and strong canines that might be dangerous in the wrong hands. A Malamute is likely to be more aggressive if it has experienced maltreatment or a negative rescue shelter experience. Kindness will, therefore, stop this dog from acting violently toward others.
Cane Corso

The Italian Mastiff, also called Cane Corso, is commonly seen as a loyal companion or a dependable guard dog. Due to its assertive nature, the Cane Corso has a history of being utilized in hunting. However, they are generally unfriendly towards strangers, particularly when meeting them for the first time.
Bullmastiff

While Bullmastiffs are not typically aggressive, they are highly fearless, and if not adequately trained, they can cause injury to a person or animal. Owning a big dog comes with significantly more responsibility because of their potential for causing damage. Therefore, individuals who are considering adoption should thoroughly think over their options.
Belgian Malinois

Often used in police and military work, Belgian Malinois are brilliant and energetic. These traits make them excellent working dogs but can lead to aggression if not properly channeled. They need extensive training and plenty of physical and mental exercise to stay balanced. Their natural wariness of strangers can turn into aggression without proper socialization.
Great Dane

With the right guidance and attention, Great Danes have the potential to become affectionate and kind-hearted giants, fitting naturally into the emotional and sensitive category of dogs. However, without proper training, they can develop into formidable creatures, and due to their immense stature, they can cause severe harm.
Argentine Dogo

This breed is frequently associated with Pit Bulls, making it one of the most feared dog breeds in terms of its potential danger. Unsurprisingly, Argentine Dogos have impressive physical strength and a powerful bite. Despite being considered dangerous, they are loyal and protective of their families. However, their dominant and territorial behavior may lead to aggression towards strangers or other animals.
Kangal

The Kangal dog breed is not to be taken lightly, as its bite is even mightier than that of a lion. This breed is known for its impressive size, as it was deliberately bred to deter predators like wolves, bears, and jackals. They can be an excellent choice as a guard dog, a working dog, or a fantastic addition to your family with the proper training and socialization.
Boxer

These skilled hunting dogs have long been used as attack and guard dogs since their breeding. Their powerful jaws and bite make them perfect for protection! Without proper training, Boxers have the potential to become extremely aggressive attackers! When training boxers, it is crucial to remember that resorting to harsh treatment can exacerbate the situation.
