"Copper, huh? Alright, I'm fine with that." It may not be a real name, but at least it sounds less embarrassing than Tongues.

Brimstone's question is a good one - which is to say, she's not sure how to answer it. In theory, it sounds about right, and it would be perfectly logical for a guard dog to be good at that, but in practice, over the past two weeks, she has been aggressive to people around the house for no good reason. Though maybe that's more of a personality problem than an olfactory one.

"... I can probably tell when someone's from outside the house."

Would that really help, though?
