Navy sailor Shelby Smith was tapping his toes and wringing his hands in anticipation at the airport.
"I don't get nervous, but today is a good day. Excited he gets to come home," Smith said.
After months overseas, German Shepherd Nathan is entering retirement and joining the civilian life with his former partner.
Nathan and Smith worked in an explosives detection unit based in Italy. Last year, they were deployed to locations in the Middle East.
"I spent a lot of time with home one-on-one, away from my family. That was the only family I had," Smith said. "If I was feeling bad, he was feeling bad. If I was happy, he was happy. He was a bended ear that I could talk to when I missed home."
Smith came back to the U.S. in August and had to leave Nathan in Italy, but four months later, Nathan is home for good.
At 10 years old, Nathan's bomb sniffing duties are over. He's still Smith's partner, but with more perks.
"Just going for walks, car rides, just living the good life," Smith said.
The non-profit organization Mission K9 Rescue paid for Nathan's flight from Italy to Houston. Their goal is to reunite working dogs with their former partners, or to find good homes for them after their jobs are done.
