A woman needed 40 stitches after she was mauled by a dog in a Sheffield street.
The 31-year-old was attacked as she walked along Richmond Road, Woodthorpe, last Saturday night.
Details of the attack have just been released by South Yorkshire Police today, with officers keen to trace the dog responsible, which is believed to have been a stray Shar-Pei type.
The woman was attacked as she approached the dog to check whether it was wearing a collar.
South Yorkshire Police said she suffered 'serious scarring' in the attack.
A South Yorkshire Police spokeswoman said: "A 31-year-old woman was walking along Richmond Road, Sheffield, near to the fish ponds, when she was attached by a dog.
"As she was walking along the road, she saw what is believed to be a stray Shar-Pei type dog that was brown in colour, on its own on Richmond Road.
"Upon approaching the dog to see if it had a collar, the dog has bitten the woman’s face. After trying to push the dog away it also bit her hand.
"The 31-year-old had to have 40 stitches after the attack and has been left with serious scarring.
"At this time the police have no lines of inquiry, but would like to speak with anyone who may have witnessed the attack or may have seen the dog."
