Pen Farthing believes war creates strong bonds between those who experience it together -- but they don't both have to be human.

On Sunday, CNN recognized him as its 2014 Hero of the Year for helping reunite soldiers who served in Afghanistan with the stray cats and dogs they befriended while abroad. In 2007, Farthing launched Nowzad Dogs -- the only animal shelter in Afghanistan, based outside of Kabul -- which has connected nearly 700 soldiers with cats and dogs they grew to love while serving in the military.

In addition to connecting soldiers who've left Afghanistan with their pets, Nowzad Dogs also spays, neuters and vaccinates street animals against rabies, which helps protect local residents' health.

“Dogs are known for their loyalty and companionship, whether it’s a normal dog in someone’s home or in Afghanistan, in my case,” Farthing explained to Yahoo News of a four-legged friend that kept his spirits high. "Just spending that little bit of time was a way of just dealing with that stress."

Farthing, who served as a Royal Marine sergeant in the British army, will be rewarded $100,000 for his cause, as well as the $25,000 already given to him for becoming a top 10 finalist.
