this is the first movie in the franchise to have 2 death scenes. the first death scene happens at the beginning of the movie and in Daria's flashback, where Daria's mom was killed by other wolves. this is completely off-screen, but we still hear growling, beating and what appears to be sounds of Daria's mother being possibly strangled.
Floyd hides in a bush and watches in horror as Daria's mom gets killed. The camera's focused on Floyd's reaction, so nothing's shown.
there's a fight scene near the end, where Kate and Humphrey battle the bad wolves to protect Daria. A little blood can be seen briefly, but it's not graphic at all.
a wolf snaps another wolf's neck. the sound of neck snapping can sound pretty painful.
in the second death scene (that happens on-screen), the villain's killed by the ghost of Daria's mother.
in some scenes of the movie, it's implied that the main villain (Head Wolf) also killed a few other wolves in Daria's pack who disobeyed him (presumably Daria's dad too) but they never show it.
