Dusty

Ranch hand Tom Lincoln (Bill Kerr) buys an adorable puppy named Dusty and trains it to herd sheep. The puppy grows to be a loyal dog, but Tom finds out that Dusty is half wild dingo and has a violent streak. Though Dusty is the best sheep dog around by day, he roams at night and may pose a danger to the livestock of others. When the ranchers call for Dusty's extermination, Tom's loyalty is tested, and he must determine how far he is willing to go to keep his dog alive.
