I don't know if it's possible at the end though I'm trying it too

My yorkshire is Italian and he's been living his first 9 months (from 2mth - 11 mth - from when he started to listen to people) in Italian language.
But when I got him, I'm Indonesian, so often, I also talk to him in Indonesian, English, and Italian, I think now he's getting used to it.
I'd say he could become trilingual later
