White Fang (1993)

Matt and his dad, Judge Adam Scott, save an Alaskan Malamute named Fang from the clutches of a vicious man who uses dogs in unlawful fights. Kate, Matt's mom, tends the wounded animal. At first, Fang is left outside at night. But when Fang saves the Scott family from his evil owner (who came to steal Fang back), Fang is accepted into the family and dons a red bandana as his collar.
