10 Dangerous Dog Breeds to Watch Out for This Summer

10 Dangerous Dog Breeds to Watch Out for This Summer

The summertime is a great time to go outside and play with your dog in the park, take your pooch for a walk, and generally enjoy the outdoors together. However, you should be aware that other dog owners who might not be as responsible as you will also be taking their dogs outside and off the leash more often. For this reason, the summer is sometimes called “dog bite season” among personal injury attorneys who help people file dog bite claims against negligent or reckless dog owners.

What is the Most Dangerous Dog in the World?

While any dog can be aggressive if raised to be, it helps to know which breeds are historically and statistically more dangerous than others. If you see any dog off a leash in your park or neighborhood, you should try to keep distance, especially if they are on this list.

Pit Bulls

It has been estimated that nearly 75% of all dog attacks in the country that cause a fatality involve an aggressive pit bull. For this reason, pit bulls are statistically the most dangerous dog breed in America if not the world. The species has a background as a pit fighter, as the name implies.

In the past, Pitbull breeders would make them inhumanely fight other dogs, people, and even bears. The selective breeding techniques caused pit bulls to have a tremendously strong bite force despite their relatively small size.


Another dog bred to be fiercely protective, the Rottweiler is statistically the second-most dangerous dog breed in the country. About 7% of all fatal dog attacks each year are caused by Rottweilers. Weighing up to 130 pounds in large males, Rottweilers can also inadvertently injure people by knocking them over while greeting or playing with them.

American Bulldog

The American bulldog is also responsible for approximately 7% of yearly fatal dog attacks. Despite its somewhat small size and stature, the dog can be aggressive towards small children and pets, especially when intentionally trained to be overly protective. The small size of the dog makes it a popular choice as a guard dog for people in small apartments or homes with no yard.

German Shepherd

In the past, German shepherds were bred to be work and guard dogs. The breed blends speed, strength, and intelligence into one comparatively small animal, weighing up to 100 pounds at most. Today, some people still train them to be aggressive household protectors, which can make them dangerous when in public or around other dogs. About 6% of all dog attack fatalities each year can be attributed to a German shepherd.

Siberian Husky

A recent growth in demand for Siberian huskies has caused more breeders to start working with the breed. However, these breeders often do not have a familiarity with what it takes to breed and raise these dogs. As a result, anyone who purchases a Siberian husky from an inexperienced breeder could be getting an unruly animal.

Furthermore, huskies have a thick coat that must be manually and continually shed in warmer climates. When its coat is not removed properly, a husky can become agitated and irritable as its temperature rises.

Up to 5% of fatal dog attacks in the U.S. each year are caused by angry Siberian huskies.


It takes about three years before a Boxer fully develops its personality and intelligence. This breed requires training throughout those formative years to behave itself and act maturely. Otherwise, its instincts as a dog bred to fight could become problematic and turn the animal aggressive. Boxers are known to cause a small but not insignificant percentage of fatal dog attacks each year.


The average bullmastiff is a big dog, standing more than two feet tall at the shoulder and weighing more than 100 pounds. The sight of a bullmastiff is intimidating, which is why you can often find the animal on security products. Again, this dog was bred to be protective of its territory, so owners must always be cautious whenever introducing a stranger to their bullmastiff.


The bigger cousin to the Siberian husky, the Alaskan malamute also has the potential to be dangerous when raised incorrectly. Malamutes are known to become upset if approached while eating, likely due to its instinct to protect a hard-fought meal in the Alaskan snow fields and tundra. Many malamutes also have a noticeable hatred for felines, making them ill-suited to live in the same house as a pet cat.


Following the popularity of the famous TV series Game of Thrones, more people than ever have wanted to own a wolfdog as a pet. As the name suggests, wolfdogs are closely related to wolves, with some breeders pairing wolves with German shepherds and other large canines to produce a litter of wolfdogs. To say that the animal’s predatory nature is intense is an understatement.

Cane Corso

One of the largest dog breeds readily available in the United States, the Cane Corso is known to be greatly obedient to one person and one person only. The breed is a favorite among people who live alone for that reason, especially if they are in an unsafe neighborhood. An improperly trained Cane Corso could pose a threat to new visitors or anyone it encounters while on a walk or at the park.
