Stolen Dog! Please help if you can!

Dozer was stolen from my son James, Tuesday, January 30th, from the cab of his red Toyota pickup.
They were parked outside a truck stop off highway 40, westbound, about an hour to an hour and a half from the Oklahoma line. Please keep your eye out for Dozer. We are heartbroken over this.
Here is a picture of Dozer. This was when he was pup, but he looks the same now, just bigger.






If anyone has any suggestions, we are open. Unfortunately, he was not microchipped, and we don't know if a local took him, or someone traveling on I-40.
