A man hiking Saturday afternoon on the Mt. Wilson Trail in Sierra Madre was injured after attempting to save his dog that had run off the trail, authorities said.

Sierra Madre Search and Rescue along with the Sierra Madre Fire Department responded to a report of an injured hiker on the Mt. Wilson trail at about 2:45 p.m. 

Officials said the man sustained a leg injury while trying to retrieve his dog after it left the trail. Crews from both agencies carried out a rescue operation that lasted nearly four hours.

The hiker was safely transported from the trail and taken to a local hospital for treatment.

The hiker’s dog, named Mitsy, remains missing.

Mitsy is described as an older black miniature Doberman Pinscher wearing an orange vest.

Authorities are asking anyone hiking the Mt. Wilson Trail this weekend to keep an eye out for the dog. They ask anyone who sees Mitsy to contact the Sierra Madre Search and Rescue.
