The Most Dangerous Dog Breeds in the World

#24: Tosa Inu

The Tosa was originally bred in Japan and has been around for several hundred years. It’s an extremely large – and at times – intimidating dog. Although it can be dangerous, the Tosa Inu does have several positive traits. They are known for being loyal, quiet (very minimal barking) and trainable.

What makes this breed dangerous is not only its massive size, but the fact that it was originally bred for fighting. Japan has a long history of breeding different types of dogs for fighting, and the Tosa Inu is no exception.
