Regardless of whether you believe some dogs are inherently aggressive or that behavior is a result of their upbringing, it’s clear that certain breeds have garnered a more notorious reputation than others. To help you avoid them, here are 17 dog breeds known for their history of aggression and considered the riskiest.
Dalmatian
Dalmatians are most famous for their distinctive black and white spotted coats. Because they used to be used as carriage dogs, they’re rather protective in nature. They are also known for being rather high-strung and touchy around strangers at times, so Dogster recommends ensuring they are well-socialized to prevent them from becoming aggressive.
Great Dane
Great Danes are known for being gentle giants, so you usually have nothing to fear when you see one bounding towards you. However, as one of the largest breeds in the world, their incredible size alone can make them a danger in aggressive situations.
Pit Bull Terrier
Pit Bull Terriers are famous for their powerful build and jaw muscles. Sadly, they have historically been used in dog fighting, which has given them more of a reputation for being aggressive. These dogs are statistically more likely to attack humans than any other breed, but with the right training and socialization, they can grow up to be docile and well-mannered.
Rottweiler
Rottweilers are currently second only to Pit Bulls in their likelihood of attacking people. This is unfortunate because these dogs are also known for being confident, strong, and proficient in many working roles. Thankfully, when they are given consistent training and early socialization, Rottweiler attacks are much less likely to occur.
German Shepherd
German Shepherds are exceptionally versatile and intelligent, which is why they’re used in so many military and police roles. Unfortunately, their protective instincts can manifest as aggression when not managed correctly. However, German Shepherds can still make great family pets when they’re trained and socialized properly.
Doberman Pinscher
Doberman Pinschers are wonderful dogs famous for their loyalty and cautiousness around strangers. While these qualities make them great personal protection dogs, they can also become aggressive when provoked or threatened. To mitigate this risk, it’s important to socialize and train them thoroughly from a young age.
Bullmastiff
According to the PDSA, Bullmastiffs are natural guard dogs that have been bred specifically to hold intruders down until they can be arrested. As you can imagine, in the wrong hands, these powerful dogs can become aggressive and dangerous, so it’s essential that they’re given all the training and socialization they need.
Siberian Husky
While Siberian Huskies aren’t usually aggressive, they are significantly larger and stronger than many other breeds. This means that when they do turn on people, the results can be life-threatening. Luckily, as long as you give them plenty of exercise, engagement, and socialization, you’re unlikely to have any issues.
Alaskan Malamute
Like Siberian Huskies, Alaskan Malamutes were originally bred as sled dogs and are known for being big and strong. They also have a strong prey drive, which can lead them into aggressive tendencies when not managed correctly. For these reasons, it’s recommended that you only adopt one of these pups if you’re fairly experienced and up for plenty of exercise.
Wolf Hybrid
As its name suggests, a Wolf Hybrid is a cross between a domestic dog and a wolf. Because this breed is much more closely related to wolves than others, it exhibits wilder, more unpredictable behavior. This is why its ownership is illegal or restricted in many areas.
Boxer
Boxers are famous for their playful nature and boundless energy. While most owners have no issues with them becoming aggressive, their protective instincts and size can make them risky to others in the wrong hands. Therefore, it’s necessary to provide consistent training, leadership, and socialization to keep them healthy and obedient.
Chow Chow
The Chow Chow is known for being somewhat aloof and aggressive with strangers in some situations. Their territorial nature also makes training even more important to avoid any issues. However, with a confident owner who sets clear boundaries, these dogs can be exceptionally loyal and loving with their families.
Akita
First bred in Japan, the Akita was originally used for protection and hunting. While they are very loyal and protective, these natural instincts can manifest as aggression in certain circumstances. Therefore, before getting an Akita, it’s essential that you understand their specific traits and are ready to take on the challenge.
Cane Corso
According to the AKC, Cane Corsos are incredibly muscular and often weigh over 100 pounds. These Italian powerhouses are also very energetic and protective, so it’s important that their owners are strong and firm enough to handle them. In the worst cases, they can become aggressive and attack other dogs and people.
American Bulldog
The classic American Bulldog is confident, strong, and excels in farm and guarding roles. However, without the proper socialization and training, they can develop an aggressive streak. To mitigate this risk, their owners should provide a strong sense of leadership and consistent guidance.
Shar-Pei
Shar-Peis were first bred for hunting and farm protection, but unfortunately, they were also later used in dog fighting. They’re known to be rather independent and aloof around strangers, which can sometimes turn into aggression. However, with the right socialization and training, they can be well-rounded members of the family.
Belgian Malinois
The Belgian Malinois is strong, energetic, and intelligent, which is why they are commonly used in military and police roles. Unfortunately, they can sometimes become overly protective and aggressive without the proper training. It’s recommended that owners are experienced and active enough to handle their training and exercise needs.
