I don't believe I ever specified who the Tailless Wolf was. My intention was to leave the last wolf up with that dubious honour- that having turned out to be
Malkatoj, and I've edited my last narration with an extra line accordingly.
However, if I ever stated that
Amanaduial was the tailless wolf... then I guess there will just be two conflicting versions, ala Tolkien. Which one do YOU think is canonical?
