sry i watch anime and jdrama alot, but my japanese rlly suck, i'm just putting words together like watashi =''i'' and kanojo = ''girl'' and petto = pet

I'm originally viet, born in america i got into anime then jdrama

From the sentence I take it that you are a young guy... you could say "boku wa" instead of "watashi wa." "Boku" is "I" used by boys/young guys, and it suits a situation where a guy says he's her pet (= the cuter being). So you can say:
- Boku wa kanojo no petto.

If you mean that you are her pet in the sense you do everything she tells you to do, then you *could* say: "
- Boku wa kanojo no iinari" (I do everything she says.)
