The wolf pack howls on average for 85 seconds. It is usually started by a single wolf, after which other wolves may join in. The pack leader, the alpha wolf, usually uses a lower-pitched howl and howls more frequently than wolves standing on the lower rungs of the pack's hierarchy. Although some functions of the howling are still unknown by scientists, they believe that wolves may howl to scare off other wolf packs from their territory and to gather their own pack, as wolves possess perfect hearing and their howling can be heard for up to in the forest and in open space. Researchers have found a relationship between the number of times a wolf howls and the strength of their relationship with other pack members. According to Friederike Range, co-director of the University of Vienna's Wolf Science Center, "the strength of the relationship between wolves predicted how many times a wolf howled."

Teenage Tibetan Mastiff Bodi (Luke Wilson) is expected to be the next guard of the village of Snow Mountain, succeeding his father Khampa (J. K. Simmons), who years ago drove out a pack of gangster grey wolves, led by the villainous Linnux (Lewis Black). Khampa has some local sheep disguised as Mastiffs to give the illusion the village has multiple guards to keep the wolves at bay, but Bodi has trouble perfecting his father's signature move the Iron Paw, which projects a powerful blast that can only happen if Bodi "finds the fire." Khampa has forbidden music in the village as it distracted Bodi from his duties when he was younger.
