Begob, in the moonlight I’m thinking you are right to choose the other way, and it’s he way I’d choose myself if had their blood in my veins, on nights like this when we’ve been looking at the full moon, my dog and I, ever since she ruz.
This is from 'The Story of Mona Sheehy' by Lord Dunsay.
Please teach me the meaning of "ever since she ruz"
