We all know leave a dog in the car can be fatal, but there is another reason not to leave your pooch behind.

One customer was left with more than just a guilty feeling after leaving his furry friend in the front seat.

After nipping to the shop to get a paper, the man came out to find his car had vanished.

After avidly questioning passers-by for information, one customer calmly remarked: "Ah yes... I saw a dog driving it down that hill."

As it turns out, his beloved companion had climbed into the driver's seat, catching its leash on the gearstick in turn. The dog "drove" down the hill and crashed into a set of parked cars.
