Top World's Deadliest Dog Breeds

Indeed, dogs may look adorable and all kinds of cute.

But all dogs are different, even within the same breed.

And especially for some new and aspiring furry owners out there, we suggest choosing a friendlier canine breed to start with.

So, what are some of the deadliest dogs in the world?

It's important to note that some dogs have been bred or trained to be more aggressive.

Whether for work or sport, some breeds were raised for their strength, size, aggression, and tenacity.

And these mighty Fidos made it on our deadliest dogs list today.

Let's get to know them, shall we?

World's Deadliest Dogs: An Overview

With dog bites occurring about 4.5 million times per year in the US alone, it pays to be cautious.

In fact, most recent studies found dogs to be the 2nd most dangerous nonvenomous animal in the U.S.

And dog bites can happen even in the comforts of your home, according to Dr. Randall Loder:

More occurred in the summer and on weekends and 80.2% occurred at home.

However, the deadliest dog tag doesn't necessarily label a canine bad.

Rather, it means these dogs pose a bigger risk in case of aggression or improper handling due to their strong bite force, overall power, and size.

Important: All dogs on this list need experienced owners, socialization, and obedience training from a young age.

But getting to know some dog breeds can give you a general idea of the temperament and personality traits that you can expect from a pup.

If you have small children, elderly relatives living in your home, or frequent visitors, choosing one of these deadliest dogs may not be the best option.
