I love this video.

It was originally uploaded back in May.  However, it's being shared by everyone and their brother on Facebook lately.

Military Sgt. Jason Bos greeted his coworker — a the bomb-sniffing dog Clia — with a big hug as she got off the plane at Chicago O’Hare International Airport. The pair worked together for five years, and Bos is adopting the dog as her military career ends.

Apparently, it's not easy to adopt these dogs who serve our country. The veterans who do adopt their K9 partners work tirelessly to get them back.
