Clash of the Wolves on AllMovie

Filmed on locations at Joshua Tree National Monument and Chatsworth, CA, this surviving Rin Tin Tin melodrama features the famous canine as Lobo, the "half-breed" leader of a pack of wolves. When forest fires ruin their habitat, the starving animals trek down into the desert, where they in desperation attack the local cattle. Wounded by a treacherous cactus, Lobo is nursed back to health by young borax prospector Dave Weston (Charles Farrell), but is forced to wear a disguise lest he becomes the target of the irate ranchers. Nasty Borax Horton (Pat Hartigan), a claim jumper masquerading as the town chemist, becomes a threat to both the dog, who has a $100 reward on his head, and Weston, who has struck pure borax. On his way to stake his claim, Weston is followed by Horton, who seriously wounds him in a fight. Lobo, however, manages to alert Dave's girlfriend, May Barstow (June Marlowe), and Horton gets his just dessert.
