Greg Mahle with a dog

On 28 Mondays a year, Greg Mahle climbs into his semitractor-trailer in Zanesville and heads south on a mission through Texas, Louisiana, and Mississippi to give formerly homeless dogs the loving homes they deserve.

One of his first stops on the weeklong, 4,200-mile journey is Shaggy Dog Rescue in Houston, where he finds dogs waiting for him that have been saved from overcrowded shelters across the Lone Star State.

Mahle gets the dogs into kennels, which are then secured — three shelves high — along the walls of his custom-built, air-conditioned trailer. Though they don’t realize it, the dogs have taken their first step toward much better lives, thanks to Rescue Road Trips, the nonprofit organization Mahle founded.
