Now this will likely stimulate disagreement but I don't think it is sanitary to bring poop-smelling and everything-licking dogs into a human bed. But even if that was ok, this is a 6 year-old dog that she knew next to nothing about which had already bitten a human within the first week.
And what is with her hair? Did the dog cut her hair and then euthanize himself just to avoid having to look at her?
I'm going out on a limb and guessing that this isn't the first short-term relationship she's brought to bed.
