The woman died at the scene.
The Madera County Sheriff's Office says deputies found the dogs that were involved in the attack and their owner, who is cooperating with the investigation.

The dog is described as a white-colored pit bull mix.
The sheriff's office is now urging residents to be vigilant and call 911 if they see any loose dogs they may be a threat.
