After healing her you get to name it and she followed me to my destination and even helped out but once it was over she was gone.
Shame really as it was nice having 2 companions for a while.
Does anyone know if we meet up again?
hmm, haven't found a namable dog yet, just dogmeat, and the dog seller, but no others (well aside from hostile ones) doubt there's much too it other than that one encounter.
