The Crup originated in the southeast of England. It closely resembles a Jack Russell terrier, except for the forked tail. The Crup is almost certainly a wizard-created dog, as it is intensely loyal to wizards and ferocious towards Muggles. It is a great scavenger, eating anything from gnomes to old tyres. Crup licences may be obtained from the Department for the Regulation and Control of Magical Creatures on completion of a simple test to prove the applicant wizard is capable of controlling the Crup in Muggle-inhabited areas. Crup owners are legally obliged to remove the Crup’s tail with a painless Severing Charm while the Crup is six to eight weeks old, lest Muggles notice it.
