YORKSHIRE has a new superhero. She has the speed of a whip, the heart of a lion and the fastest jaws since Murray Walker.

Beauty the Jack Russell is a true wonder dog: a latter-day Lassie. When her master, Bill Agar, was faced with a knife-wielding intruder, she joined him in the fray in a flash.

She is no Rottweiler, but this terrier has a fine set of teeth and knows how to use them.

Now one sore criminal has learned his lesson. Never again will he try to force his way into Beauty's parlour.
