A Jack Russell named Diesel has been rescued uninjured from under the engine of a moving car after he traveled on a busy highway for half an hour. Diesel's owner had been traveling along the Hunter Expressway in New South Wales on Tuesday afternoon when they heard a familiar howling. The 18-month-old stowaway had hitched a ride under the bonnet of the Hyundai SUV from Singleton to Branxton as the car reached speeds of up to 100km/h. Diesel the Jack Russell is one very relieved pooch after he was rescued from under a car engine by firefighters on Tuesday (pictured: Diesel after being safely rescued)
