While Staff Sgt. Edwin Caba served in Afghanistan, a litter of puppies born on his base brought a sense of much needed joy and relief to the soldiers. Many didn't want to part with the dogs once their tour ended. Enter Nowzad Dogs. Since 2007, the nonprofit has reunited more than 700 soldiers with the animals they cared for on duty. As the only official animal shelter in the country, it also helps find homes for abandoned animals in Afghanistan. Founder Pen Farthing, a former Royal Marine sergeant, named the organization after Nowzad - a dog that adopted Farthing, and followed him back to base after he broke up a dogfight. The dog had such an effect on Farthing that he found a way to take her home. In doing so, he realized he wanted to help others do the same.
