A PITBULL terrier has bit off the tip of a woman's finger as she tried to stop it from mauling her Jack Russell while she was walking in Sydney. The dog has been taken under the control of City of Sydney Council. The pitbull's owner, an 80-year-old woman, had been walking the dog in Pyrmont early on Wednesday morning when it attacked the Jack Russell, which was running around the park off its leash. The pitbull mauled the 43-year-old woman as she tried to protect her Jack Russell. Police separated the dogs and the woman was taken to hospital for surgery.
