The San Diego Humane Society said in a Facebook post that an officer responded Monday when the 8-year-old Australian shepherd, named Hobo, fell down the ravine while a fence was being constructed around his family's home.

"Members of the ERT Technical Response Unit rushed to the scene, setting up safety lines to rappel down the steep terrain. Five team members were required to cut the dog free from brush with a saw before securing him for the climb up," the humane society's Facebook post said. Hobo was reunited with his family at the end of the four-hour rescue.
