I'm just saying that even if it is a clue to who his parent is, Lupa is a wolf after all so maybe people could see that as Lupa's shadow, she does help train the new campers after all. I still think it looks like a bear, which would work as Frank was almost attacked by a bear when he was younger, which his mom fended off...but it could be a wolf.
