A 55-year-old woman has died after being bitten by a dog while defending her own pet from an attack, police have said.
Sharon Jennings was walking her dog between 6pm and 7.30pm in Preston, Lancashire, just over a week ago before it got into a fight with the other animal.
She was bitten on the hand and neck as she tried to break the animals up after a fight had broken out on the old railway lines in Brookfield on 31 May, Lancashire Constabulary said.
Her dog suffered an injury to its ear and was treated by a vet, however Ms Jennings did not seek medical attention.
She was found unwell at her home on Monday and taken to Royal Preston Hospital, where she died on Friday night, the force added.
Police are trying to track the owner of the dog which attacked her.
The owner is described as being male with thinning grey-black hair, and was wearing a blue fleece jacket at the time of the incident.
His dog is described as “a speckled ginger-and-black canine of medium height”.
Detective Inspector Chris Wellard, of Preston Police, urged the dog’s owner or anyone with information to come forward.
He said: “Our thoughts are with Sharon’s family and friends at this incredibly distressing time.
“We’re working hard to establish what happened but need anyone with information to come forward as soon as possible.”
