How can I show my therian girlfriend that I support her?

My (F14) girlfriend (F15) and I have been together for about 4 months now, and she's just recently come out to me as a therian. I told her I was happy she felt she could share this with me, and that I'd support her no matter what. However, how do I show that?

I've done some research on therianthropy, I know the basics of what it is and where it came from, but I'm still a bit confused on some of the more specific details.

For example, the other day we were texting me and telling me how she experienced her first shift, and I was clueless. I further asked her about it, but she used all of these terms that just confused me even more lmao. I didn't wanna complicate things any further, so I faked an understanding, and called it a day.

Anyways, I guess the main thing I'm asking is just a quick run down of things I should know about therianthropy, and what I can do to uplift my girlfriend and make her feel valid.

Edit: I should probably also mention that her theriotypes are a Border collie and a Norwegian forest cat
