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."
The Pack (1977 film)
McMinnimee, who lives in a cabin alone with his German Shepherd Shazah, soon learns of the wild dog and returns to his home. When a storm hit the island one evening, Shazah starts up a riot and tries to break out. Armed with his rifle, the old man opens the door to his cabin and tries to find out who is intruding onto his property. Shazah bolts out into the front yard, but is suddenly attacked by the golden-haired mongrel and several other feral dogs. McMinnimee is too late to save his dog from the pack, though he manages to shoot and kill a collie, one of the pack members. As he tries to secure the door and windows to his house, the dogs break through one of the windows and attack the old man, killing him.
