Most Dangerous Dogs: Understanding Breeds and Prevention


When it comes to dogs, some breeds are more prone to aggression than others. While any dog can bite or attack if provoked, certain breeds have a reputation for being particularly aggressive due to their size and strength. In this article, we will explore which breeds are considered the most dangerous and why, as well as examine the historical context, expert opinions, statistics, and prevention methods related to these breeds.

Listing the Breeds

There is no official list of the most dangerous dog breeds, as opinions vary on what constitutes a “dangerous” breed. However, there are several breeds that are commonly cited as having a higher propensity for aggression and/or attacks. These include the Pit Bull, Rottweiler, German Shepherd, Doberman Pinscher, Chow Chow, Akita, Presa Canario, Wolf Hybrid, and Alaskan Malamute.

The Pit Bull is one of the most controversial breeds, with its reputation for aggression and attacks. The breed was originally bred for fighting and has a strong jaw. Despite its reputation, the Pit Bull is often loyal, affectionate, and gentle when properly trained and socialized. Similarly, the Rottweiler is a large, powerful breed that can be aggressive if not properly trained. This breed is known for its protective instincts and intelligence, making it an excellent guard dog.

The German Shepherd is another popular breed that is also known for its intelligence and loyalty. This breed is often used in search and rescue operations and is highly trainable. The Doberman Pinscher is a powerful and energetic breed that is often used as a guard dog. This breed is loyal, brave, and alert, but can be aggressive if not properly trained. The Chow Chow is a large, independent breed with a strong hunting instinct. This breed is often aloof and can be territorial, making it important to socialize them early on.

The Akita is a large, powerful breed that is known for its courage and loyalty. This breed requires firm training and should not be left unsupervised with children. The Presa Canario is a large, muscular breed that was originally bred for hunting and guarding. This breed is strong-willed, courageous, and loyal, but can become aggressive if not properly trained. The Wolf Hybrid is a mix of a wolf and a domesticated dog, and is not recommended as a pet due to its unpredictable behavior. Finally, the Alaskan Malamute is a large, strong breed that was bred for sledding and hauling. This breed is loyal and intelligent, but can be difficult to train and can be aggressive if not properly socialized.

Historical Context

The breeds listed above were all bred for specific purposes, and many of them were bred to be aggressive. For example, the Pit Bull was originally bred for fighting and has a strong jaw. Similarly, the Rottweiler was bred for protection and herding, while the German Shepherd was bred for guarding and police work. The Doberman Pinscher was bred for protection and guard duty, and the Chow Chow was bred for hunting and guarding. The Akita was bred for hunting, the Presa Canario for hunting and guarding, and the Alaskan Malamute for sledding and hauling.

It is important to note that while these breeds may have been bred to be aggressive, they can still be loving and loyal companions when properly trained and socialized. Unfortunately, some people do not take the time to train and socialize their dogs, leading to incidents of aggression and attacks.

Expert Opinions

In order to gain a better understanding of why certain breeds are considered more dangerous than others, we spoke to experts in animal behavior. Dr. Jennifer Shryock, an expert in canine behavior, explained that “certain breeds are more likely to display aggressive behaviors due to their breeding and history.” She went on to say that “these breeds tend to have a higher threshold for pain, which can lead to aggression if they are not properly trained.”

Dr. Elizabeth Strand, an animal behavior specialist, echoed these sentiments, saying that “it is important to understand the history of these breeds and why they were bred to be so aggressive.” She also noted that “proper training and socialization are essential for these breeds, as they can become dangerous if not handled correctly.”


According to the Centers for Disease Control and Prevention (CDC), the Pit Bull is responsible for the majority of fatal dog attacks in the United States. The Rottweiler, German Shepherd, Husky, and Bullmastiff are also among the breeds most commonly associated with fatal dog attacks. In addition, a study published in the Journal of the American Veterinary Medical Association found that the Pit Bull was responsible for the highest number of reported bite incidents in 2017, followed by the German Shepherd and Rottweiler.

Training Tips

It is essential that owners of these breeds take the time to properly train and socialize their dogs. Professional trainers can help owners learn how to effectively manage their dogs and teach them proper behavior. Positive reinforcement methods such as reward-based training can help owners build a positive relationship with their dogs and encourage good behavior. Owners should also ensure that their dogs get plenty of exercise and mental stimulation to help reduce aggressive tendencies.


In some areas, owning certain breeds is prohibited or restricted by law. For example, the city of Denver, Colorado has a ban on owning Pit Bulls, and other cities have similar laws. These laws are intended to protect the public from potentially dangerous dogs, but they can also be problematic for responsible owners who have properly trained and socialized their dogs. It is important to research local laws before owning one of these breeds.


The best way to prevent dog bites is to educate yourself on the breed you are considering and ensure that you are prepared to handle it responsibly. Knowing the breed’s history, temperament, and needs is essential for proper care and training. Additionally, it is important to socialize your dog from a young age and provide them with plenty of exercise and mental stimulation. Lastly, if you are ever in doubt, it is best to avoid unfamiliar dogs and consult with an animal behavior professional if needed.


Certain dog breeds are considered more dangerous than others due to their size, strength, and history. While these breeds can make great companions when properly trained and socialized, it is important to be aware of their potential for aggression. Understanding the history, expert opinions, statistics, and prevention methods related to these breeds can help owners make informed decisions and keep their pets and the public safe.
