The dog of a slain NAVY Seal refused to leave his owner's side during Petty Officer Jon Tumilson's funeral earlier this week in Rockford, Iowa.

Heartbreaking photos taken by his cousin shows Tumilson’s dog Hawkeye lying by the casket.

Tumilson was among the 30 American troops killed August 6 when Taliban insurgents downed their Chinook helicopter with a rocket-propelled grenade.

At his funeral in Iowa, his dog Hawkeye paid his last respects, walking up to the casket, lying down in front of it, and heaving a sigh.

According to friends of the lost SEAL, to say he was amazing doesn't do him justice.  His loss is immeasurable.

Family and friends posted this looping, time lapsed video of Hawkeye at the service.
