Teeth

Dan Angus, train baggage master, mistreats two dogs in his care, throwing the small one off while the big one attacks him. Dan is fired and gets off at a small town, steals from the postmaster and kills him. Dave, a prospector, finds the large dog and re-christens him "Teeth." Paula, the owner of the dogs, comes back to the town to find them. Dan frames Dave who is arrested for the murder, but with the aid of Teeth escapes to the woods. Paula follows with Dan after her. Dan attacks Paula and puts her in a cabin, accidentally setting the forest on fire. Teeth gets Dave who rescues Paula. Dave takes her to a waterhole while Teeth brings the horse Tony. After the fire, Dan who has been caught in the flames confesses and Paula confesses her love for Dave, thus ending the dispute as to which shall keep Teeth.
