Timber Wolf is very similar to:

Soto: As they both wanted to slaughter the protagonists and the babies (Timber Wolf wants to kill Benji and the Cougar cubs; Soto wants to kill Manny and Roshan). Soto wanted to do it for revenge, unlike timber Wolf. Both die in the end (Timber Wolf falls off a cliff; Soto gets killed by sharp icicles). Both attack their enemies towards the beginning (Timber Wolf attacks Benji at the hunter's cabin; Soto attacks the humans at their camp).

Dag: He is also similar to Dag from Nickelodeon's 2006 film, Barnyard, as they both are canines who try to eat their victims (Cougar cubs in Timber Wolf's case; Hens in Dag's case). Both try to kill the protagonist (Timber Wolf wants to kill Benji and the Cougar cubs; Dag wants to kill Otis).
