Navy SEAL Jon Tumilson lay in a coffin, draped in an American flag, in front of a tearful audience mourning his death in Afghanistan. Soon an old friend appeared, and like a fellow soldier on a battlefield, his loyal dog refused to leave him behind.

Tumilson’s Labrador retriever, Hawkeye, was photographed lying by Tumilson’s casket in a heart-wrenching image taken at the funeral service in Tumilson’s hometown of Rockford, Iowa, earlier this week. Hawkeye walked up to the casket at the beginning of the service and then dropped down with a heaving sigh as about 1,500 mourners witnessed a dog accompanying his master until the end, reported CBS.
