Two pitbulls attack a woman and her dogs, leaving her with injuries to her nose and leg.
The attack happened Sunday afternoon near a greenbelt in Highlands Ranch.
Police responded to a call from a witness and found the 53 year-old woman being attacked by the pitbulls.
When they got closer, the dogs turned their attention towards them and began to attack. That's when the officers pulled out their guns and fired, killing both dogs.
Two other dogs were found dead about a mile and a half from the scene. It's not clear if they were killed by the pitbulls.
Investigators are still trying to figure out who owns the pitbulls.
The woman was taken to the hospital for treatment.
