An employee from a nearby store heard the dog crying from the covered man hole. The employee removed the lid and discovered the dog and called emergency workers to the scene.
Firefighters and Riverside County Animal Services worked to rescue the dog.
Officials say the dog was shaking and had trouble walking but is expected to survive.
Animal Services is asking anyone with information about the dog or how she got in the man hole to call 951-358-PETS (7387).
