No Snopes item on it that I could find. Yet.
A charity in New Zealand is teaching three dogs to drive to highlight their intelligence and encourage more people to give rescued animals a home. The campaign is part of a push by the Society for the Prevention of Cruelty to Animals (SPCA) to find more homes for abandoned pets in New Zealand.
The three animals chosen by trainer Mark Vette are Monty, an 18 month old giant schnauzer, Ginny, a one year old whippet cross and Porter, a 10 month old beardie cross.
Their training began in September with simple movements, such as putting a paw on a mock gear stick, sitting in a driving position and holding a steering wheel. After five weeks their training progressed and movement was added by mounting training aids on a trolley. Next step for the dogs was to get in a real car, with a trainer in the passenger seat to help with the steering.
