The Pack (2015)

Man's best friend becomes his worst nightmare when a horde of bloodthirsty wild dogs descends upon a family's farmhouse. In a remote stretch of the Australian Outback, a sheep rancher (Jack Campbell), his veterinarian wife (Anna Lise Phillips), and their two teenage children live in bucolic isolation: until a horrifying night when a pack of fang-baring, four-legged, rabid beasts besiege their home. With no one around to help them, the family must band together to survive: or else become canine kibble. Generating a steadily mounting sense of dread, The Pack cleverly toys with genre conventions before it goes in for the kill.
