These gory photos capture the gruesome injuries a 12-year-old girl suffered after a devil dog mauled her at a nature reserve.
Morgan Smith was savaged by the Neapolitan Mastiff on Sunday morning in a brutal attack.
The owner had to punch the dog to get him off the youngster, Bristol Live says.
Morgan's horrified mum Rosie said: "I really want this man to be caught.
"It was such a horrific incident, the dog absolutely savaged my daughter's arm."
The child needed five stitches in A&E after the bloodshed at Stockwood Nature Reserve, southeast Bristol.
After the attack, Rosie shouted at the owner: "Put your dog on a lead."
He reportedly replied: "He's never done anything like this before."
But nevertheless, police are investigating the mauling.
Rosie added: "She was in shock and I tried to clam her down and tell her it wasn't as bad as it actually was.
"Once she had calmed down I went into shock.
"I think he was a puppy and was being more playful than aggressive.
"He wasn't wearing a collar and wasn't on a lead. Our dog was on our lead.
"I have warned by daughter's school about it."
A spokesman for Avon and Somerset Police said: "We're investigating after a dog bit a 12-year-old girl on Stockwood Road on Sunday (15 September).
"The dog was believed to be a grey Neapolitan Mastiff and its owner was described as a white man, about 5ft 8ins tall with a bald head and wearing a white polo shirt.
"Anyone with information about who the dog's owner might be is asked to call 101 and provide the call handler with the reference 5219213163."
