HAGERSTOWN, Md. (WHAG/NBC) - For some dogs, Interstate 81 Northbound is the road to freedom.
It's a little like the Pony Express, but it's the "Puppy Express," a second chance for dogs who no one thought would be alive today.
After rescues save dogs that would otherwise be put down, Movin' On Up Animal Transports drives them north.
They take them to shelters that have space for them until they get adopted.
Drivers pick the dogs up at highway exits, often in Winchester, Hagerstown, and Chamberbsurg, Maryland. Each driver takes the dog to the next checkpoint.
One recent trip brought two dogs about 1,400 miles. A pit bull named Little River and a mix Poppy, were taken from North Carolina to shelters in Vermont and Maine.
