Britney Parkerton was at a gas station in Folsom Saturday night when her 7-month-old dog Roo snuck out of the car.
Parkerton's phone number is on Roo's collar and she soon got a phone call from a man who had picked up the dog in the parking lot.
He demanded money for Roo's return.
Britney called the Folsom Police Department and officers helped her set up a sting.
Officers arrested 31-year-old Adonison Gunther of Oakland and 21-year-old Marisa Jackson. They could face charges of extortion.
