40 Dog Breeds That Do NOT Belong in Your Home!

Tosa

The Tosa is a gorgeous dog that was first bred into popularity in Japan. Originally known for being a fighting dog, rehabilitation of the breed has been going on for years. Still, due to their roots, the Tosa is known for being aggressive and dangerous when around strangers. In fact, many countries around the world will restrict the potential ownership of a Tosa due to their danger.

The Tosa was originally bred and raised in the city of Tosa, Shikoku, which is now known as Kochi, Japan. The dog still is used in Japanese dog fighting rings which is, strictly speaking, despicable.
