The 5 Most Dangerous Dog Breeds in the USA  

Dogs are among the best friends of human beings if they are trained well. However, if they are not trained well, they can feel threatened by adults and children that tease dogs and then retaliate by becoming aggressive and often bite the teasers.

Why Dogs Bite

A dog can bite when its equanimity is disturbed. Even if the owner disturbs the dog it can become aggressive. There are several reasons why dogs can bite and they could be because of the dog:

    • Is threatened by a stranger
    • Is protecting its puppies
    • Is startled by some loud noise
    • Is confused about whether to play or be aggressive
    • Is not well
  • Is suffering from an injury

Whatever be the reason dogs get disturbed like humans and can react adversely resulting in a dog bite. These dogs trouble their owners no end because when they bite people they invite lawsuits for significant costs and damages, according to Jonathan Rosenfeld, a specialist in dog bite injury claims.

Most Dangerous Dog Breeds

The most dangerous dog breeds in the USA is difficult to pinpoint. If you want to categorize by looks and size you would get one list and if you categorize by propensity to bite you would get a completely different list. Therefore, it is sensible to use data based categorization of the 5 most dangerous dog breeds in the USA.

As per a recent Ohio State University’s Wexner Medical Center study of 15 years of data and 43 separate studies dating back to the year 1970, researchers determined the relative risk of biting by various breeds of dogs. They focused on the severity of bites causing wounds, tissue tears, bone fractures and other serious injuries that necessitated the services of facial trauma and reconstructive surgeons.

Here’s the list of 5 most dangerous dogs based on relative risk of biting and you would do well to watch out for these dogs the next time you set your eyes on them and tread carefully lest they bite you:


Pit bulls trace their ancestry to terriers and bulldogs. These dogs were bred for baiting bears and bulls. They were also employed for dog fights. Pitbull breed accounted for the highest number of dog bites.

German Shepherd

The German-origin German shepherd is a fairly large dog weighing upwards of 70 lbs. These dogs are famous for their service in K-9 units for their fearlessness, alertness, intelligence and protectiveness. If not trained properly they can pose serious danger to children and adults as well.


Terriers are bred in several groups forming at least five distinct ones with different characteristics. Sizes can vary from as light as 3 lbs. to as heavy as 70 lbs. Terriers are fearless and stubborn and they can get into arguments in a jiffy increasing chances of biting. They need to be trained well.


Its reputation as a fearsome breed precedes this breed of dog. They were bred for herding animals and being guard dogs. These dogs are aggressive and intelligent. This breed causes the most deaths due to dog bites.

Alaskan Malamute

Before domestication, these dogs were sled dogs and were basically hunting dogs and load carrying dogs. They are relatively huge weighing up to 100 lbs. They have the reputation of killing larger animals such as bears. They are natural hunters and hence can get carried away when provoked.

Besides the above there are two breeds of dogs – unknown breeds and mixed breeds – that together account for the highest number of dog bites and fatalities.

As mentioned earlier, most often dogs bite people when they feel threatened in some way. It’s a natural instinct that’s still present in domesticated dogs. This is why it’s important for everyone who interacts with a dog to be wary especially when it is the first time they are meeting that dog.
