From a New York Times story by Eduardo Medina headlined “Dog Helps Rescue Owner Who Fell 70 Feet in California Forest”:

A 53-year-old man and his black Border collie, Saul, were on a hike last week near California’s Tahoe National Forest, surrounded by trees and steep canyons, when something went wrong. The man fell 70 feet from a ridge, breaking his hip and multiple ribs, the authorities said. He had no phone. Just a dog by his side.
