Officers attempted to lure the German Shepard off the road but she repeatedly ran back into traffic forcing police to temporarily shut down the road in their effort to rescue the dog.
An officer was ultimately able to lure the dog into their cruiser with a granola bar, but once inside she apparently sought to take control and drive the vehicle.
"The dog jumped into the driver's seat and sat behind the wheel," Massachusetts State Police wrote on Facebook. "Trooper Higgins got into the cruiser and got the tired pooch to move over into the passenger seat."
Once in police custody the dog, who owners said was named Lexi, was ultimately returned to her home.
