In a heartwarming project aimed at increasing pet adoptions from animal shelters, a group of cross-breed rescue dogs from Auckland were taught to drive a car -- steering, pedals and all -- to show the potential of unwanted canines.

Footage of the motorised mutts learning their skills has proved an Internet sensation but their ultimate test came on Monday, when the two best performers, Monty and Porter, were put through their paces on national television.

Monty the giant schnauzer cross was first up, driving the modified Mini down the straight by himself, in what is claimed to be a world first.

"It's all the dog doing it," trainer Mark Vette said as Monty cruised along the track looking relaxed with one paw resting on the steering wheel before coming safely to a halt.

"He's started the key, put the paw on the brake to allow it to go into gear, put it into drive, paw on the steering wheel, accelerator on, and off he goes down the track."
