A cowardly bank robber turned tail and fled when he came face to face with a post office guard dog - a tiny Yorkshire Terrier.
The man had been ransacking the tills at gunpoint in Modling, Austria, until he woke six-inch high Cica from her basket under the counter.
Witnesses said the dog leapt up and started growling and barking and the startled robber put down his gun, turned and ran.
"When she realised he was threatening me she began barking like mad and jumped at him. She didn't bite him, just scared him. He was petrified," said proud postmistress Gabriella Dreyer.
"Cica never let's me out of her sight and we can be a bit inseparable at times. She is a real hero and I think robbers will think twice about coming in here after they hear what happened."
Who Says Yorkies Are Not Good Watch Dogs?!
