What do we mean by the world’s most dangerous dogs?

All of us think of dogs as loyal. The word dog is synonymous with loyalty and friendliness. However, in the world of dogs, some breed of dogs are more “dangerous” than others. A “dangerous” dog is not necessarily aggressive. A Great Dane knocking someone down is potentially more dangerous than an aggressive Lhasa Apso.

Dog Attacks! Stats that we cannot ignore

Dog Attack Stats Info-graphic

Before we dive deep into the list of dangerous dog breeds, below are some vital stats that one cannot ignore when evaluating the most dangerous dogs in the world.

The definition of “most dangerous dog”

Dog attacking man

Before we start, it is crucial to define the term “most dangerous dog.” We used the following factors to calculate a dog’s “danger index” and ranked the dog breeds.

We used reliable and trustworthy sources to compile our list of the world’s dangerous dog breeds. Research has shown that several factors influence dog behavior, not just the breed of dog. However, we have to acknowledge the fact that statistics don’t lie. Some dogs are more prone to attack than others.

How do we rank dogs where we don’t have sufficient data?

Not every country in the world has an organization such as CDC to provide accurate data. In such cases, we used the following factors.

  • Size
  • Bred for dogfights
  • Breed

And of course, common sense. Dogs like the Kuchi dog, are dangerous and cannot be ignored just due to lack of data.

Pitbull Terrier Alert

American Pit Bull Terrier is a result of interbreeding the Old English Terrier and the Old English Bulldog. The idea was to combine the strength of the Bulldog with the gameness and agility of Terrier. It was only in the early 19th century the English Bulldog, and Terrier dogs arrived in the US. Selective breeding in the US resulted in the American Pit Bull Terrier that we see today.

They were developed initially for bull-baiting and bear-baiting, after the ban on these cruel sports, people turned these dogs to dogfighting. Breeders relied on dogfights to choose their breeding stock. These factors combined to give this dog a powerful, aggressive, and stubborn disposition.
