How many types of Tosa Inus are there?

There is technically just one type of Tosa Inu, but there can be some variation depending on where they are bred. Japanese-bred Tosa Inus tend to be smaller and more compact compared to Tosa Inus bred outside Japan, particularly in Western countries like the United States, where they’re often bred to be larger.

So, while there aren’t officially different types, you may find variations in size and weight based on breeding practices across different regions.
