The victim, 60, was trying to break up a fight between two dogs when she was bitten and screamed for help out of fear that the more aggressive dog would kill the other animal, police said.

A nearby citizen came to her aid with a firearm, according to police, and shot the aggressive dog twice after seeing that it had the other dog by the throat.
