The dog was found after a homeowner called the police to report hearing howling coming from a canal bank near Belmont Avenue and Fulton avenues.
Officers say the dog had gotten stuck in some brush and was about to fall into the canal.
The homeowner let officers cut through their fence, allowing them to safely rescue the dog.
Officers are keeping the dog safe until it can be reunited with its owner.
The owner of the dog is asked to message Fresno police on Facebook with details they would only know.
