A girl has been rushed to hospital after being savaged by a dog as she tried to help its owner fix a harness.
The incident happened in Navigation Park in Altrincham last night at roughly 9pm, police said. A man - aged around 70 - was with a dog in the park.
The victim, 17, tried to help with putting the dog's harness on when it attacked her. It savaged her face, leaving her with a 'substantial' injury to her face and cheek.
She had to go to hospital, officers said. Police have now issued an appeal for witnesses and have asked anyone with information about the man or the dog to come forward.
A post on the official GMP Trafford South Facebook page last night described the man at the scene as a white male, who was aged around 70 and around 5ft 9in tall.

He was described as being unstable on his feet and was wearing a long, brown leather jacket with a bobble hat. He also had a walking stick, the appeal added.
The dog was described as being mostly white. It looked similar to a Labrador but was thought to have been crossed with another breed and had ginger fur on its back.
The dog was also described as being skinny, 'fairly young' - around two-years-old - and had a red harness.
