This could have been the worst day of this trucker's life...and the final fun for Fido.
Dateline Yavapai County Arizona: that's where a volunteer from the Sheriff's Department spotted this big rig as it was leaving the parking lot of a gas station.
You'll note who's attached to the trailer's bumper--that's the fleet-footed Mr. Bow Wow.
The driver says, he completely forgot to grab his pooch before hitting the road.
Mr. Fido...now has a new best friend.
