The book is about a hunting dog named Jock and his owner, a transport rider, who narrates the story. When the book starts off the narrator talks about the puppies of which Jock is one. Jock is the runt of the litter but the narrator likes him anyway. As the story goes on Jock grows and learns to be a hunting dog. As you read about Jock you also read about the animals and people in the Veld during the Transvaal gold rush. The book is broken up into many stories. Most are about hunting with Jock, such as a hunt for a leopard and an old crocodile. Other stories are about people and the animals that Jock and the narrator face, such as when the duo gets lost in the bush, a fight with a captive baboon, a run from a wildfire, and an encounter with some wild dogs.
