Are Tosa Inus good with cats?

Yes, Tosa Inus can be good with cats. They weren’t bred to herd livestock or hunt game, so while they are a powerful breed, they aren’t prone to chasing or acting predatory towards household cats. This is especially true for Tosa Inus, who were raised alongside their feline counterparts. 

Of course, because of their size and strength, it’s especially important to ensure they display calm and friendly behavior before letting a Tosa Inu off-leash around a kitty. Make sure to introduce the Tosa Inu and cat slowly, starting first with scent intros and working up to in-person meetings while keeping your pup leashed and at a safe distance from the cat. Reward calm and friendly behavior, building up to longer sessions as the animals become familiar with each other.
