We brought her home today.  She's a 5mo old rat terrier.  Alice liked her at first, but was a little nervous after a while because the dog was so hyper.  Roxy has since calmed considerably, so that's better.  Our biggest concern now is what it will take for Pepper to accept her — the initial reception was not very warm.  We also worried about the chewing, but that hasn't been an issue just yet.  Mostly we're just glad to have her:  she's a really sweet dog!
