Help me build a good trans character for my visual novel plz

I'm making a romance visual novel about a tgirl working in a doggy-girl shelter and romancing one of the 5 doggies
I want her to be an ex-NEET transbian who only lives for doggy-girls and hates other people. she's forced to get a job by her parents which is why she found work in the shelter. She cares very deeply about these critters and would throw her life away for them

>Why make the protagonist a tgirl?
I like tgirls

It's shallow reasoning but I want to make her character respectful, im a foid so I can't truly articulate the trans experience

Should her transness be kept subtle or should I make it a big part of her character?
If you were in a situation where you can romance abandoned doggy girls, what would you do? How would you treat them? How do real life dogs make you feel? How would I be able to incorporate her being trans into the story?
Any story writing tips would help greatly
