Since I chose Xander's name, Derek got to choose Rex's new name.
Unfortunately, it cannot be disclosed as yet.
booling has to be told it in person before I can announce it here.
I'm certain I will continue to call her Sasha, Seffi and/or Rex anyway as part of her litany of extra names (much like Xander is Piddlepaws and The Pants among many, many others...)
And the home visit went very well, we were approved to adopt her and paid all her fees today.
We have a second crate, a couple toys to be just her very own, and the food she's currently on at her foster home.
And, it turns out, even though she's listed as a Saint Bernard, she might not have any in her at all. I'm considering a DNA test for breed, but it'll depend on cost.
Whether she is or isn't, she will always be our Miniature Giant Space Bernard....
