Four military working dogs were honored for their service at American Humane’s fourth annual K-9 Medal of Courage awards ceremony in Washington, D.C., on Tuesday.

One of them was Sgt. Yeager, a black lab trained as an improvised explosive detection dog who was on patrol with his handler, Lance Cpl. Abraham Tarwoe, on April 12, 2012, when an IED exploded. Sgt. Yeager survived, but Tarwoe did not.
