The sausage dog not only failed to raise the alarm, it was so quiet that the thief did not notice it, police said on Sunday.
The owner had parked in the underground garage of a shopping centre in the eastern city, and popped out for five minutes, leaving the dog in the car.
When the driver returned he could not find his car, nor the dog.
He is appealing for the thief to show some compassion and at least return his pet.
