UPDATE 4.30PM: City of Greater Bendigo Parking and Animal Control manager Neville Zimmer said the council was taking Monday's alleged dog attack "very seriously".
He said the attack was the most severe case the council had registered in the past 12 months.
"It's a pretty serious dog attack," he said. "There's a serious community safety issue here.
"The last thing we want is a repeat, or worse, of an allegedly unprovoked attack."
Mr Zimmer said the woman who was walking the dog pulled it off the victim then left the scene.
He said the council would be conducting doorknocks, searching its database of registered dogs and working with police to track the dog's owner.
He called on the owner to come forward.
"We are really appealing for the owner of the dog to come forward and take responsibility for the actions of the dog," he said.
"It is irresponsible if you know your dog is antisocial or aggressive. You're taking a risk to take it out in public."
Mr Zimmer said the victim had a "hell of an experience" and was still in hospital, after being admitted last night.
He said the victim was on her way to Bendigo Health to visit her mother, who was being treated there.
But instead of visiting her mother, the victim wound up being admitted to the same ward as her.
Mr Zimmer said the victim spent Monday night at the hospital and had not yet been released.
