[1] Old Dog picks up the story of a father and son against the backdrop of China's escalating trade in Tibetan mastiffs.

At first, the dealer refuses but eventually agrees when police officer Dorje (who happens to be the old man's son-in-law) explains the nature of the family conflict.

After recovering his mastiff, the old sheep herder joins Dorje for a tea and meat snack at a local eatery.

The two men share a quiet moment during which time Gonpo reveals that Rikso had gone to the hospital and was determined to have no problems in conceiving children.

While tending his sheep with his faithful mastiff and gazing upon a scenic landscape of Tibetan mountains and tundra, the old man is badgered by 2 men who offer to buy the dog.

In the final poignant scenes, the old man decides to end his dog's life by strangling him on his chain, and in minutes his mastiff is dead.
