The cruiser overturned multiple times upon impact, coming to rest on the driver's side of the vehicle.
The officer suffered major injuries and was flown to Arrowhead Regional Medical Center for treatment.
The K9 was checked at the scene and appeared to have no injuries, but was taken to a veterinarian as a precaution.

The officer, who has not been identified, has been with the department six years and was heading home after working the graveyard shift, according to CHP.
Officers out of the Victorville CHP station are investigating the crash and are urging anyone who may have witnessed the crash to call (760) 241-1186.
