Book excerpt: How far would you go to save a dog's life? The extraordinary story of one man who has driven more than 1 million miles to rescue thousands of dogs from hunger, abuse and neglect and give them a second chance at life and love. For years, Greg Mahle struggled to keep the last of his family-run restaurants afloat in Ohio. When it finally closed, he was broke and unsure what to do next. Then a stranded van-load of puppies changed his life forever. Join journalist Peter Zheutlin as he travels with Greg from Ohio to the Gulf Coast on his Rescue Road Trips to bring hard-luck dogs from the deep South to loving "forever families" up north, with the help of many selfless volunteers along the way. From Houston's impoverished Fifth Ward--where thousands of strays roam the streets--and high-kill shelters in Louisiana, to joyous scenes of adopters embracing their new pups in the Northeast, Rescue Road is full of heart: an inspiring story about the unique bond between dogs and humans, and how going the extra mile can make a life-changing difference for these loyal canines-and for us all.
