A 12-year-old schoolgirl had her lip ripped off by a dog as she walked home.
A bloody image showing the extent of the girl's injuries has been released by West Midlands Police in a bid to trace the animal and its owner.
She was bitten on her mouth and had her bottom lip ripped off as she walked through an alleyway off Ellerton Walk, Park Village, Wolverhampton, shortly after 3.30pm on Friday October 19.
The girl suffered life-changing injuries and will need extensive plastic surgery, the force said.
The dog, described as black and white and possibly a husky or German shepherd-type dog, was on its own at the time of the attack.
Police have appealed for anyone with information on the dog and its owner to contact the force.
