Nero is among five dogs to spend the last seven years sniffing out landmines and saving lives in Iraq.

Mine-detection dogs are provided to Iraq and other conflict-torn countries through an organization called The Marshall Legacy Institute, a Virginia-based non-profit humanitarian agency.

“We provide the dogs to sniff out the land mines so it is safe for children to play, for people to work, for animals to live and communities to grow,” said Perry Baltimore of Marshall Legacy Institute.

The dogs are back in the U.S. -- and looking for new homes. WRC’s Julie Carey reports in the video above.
