Treo was truly Sgt. Dave Heyhoe’s best friend. 

While in the British military, Treo and Heyhoe did a lot of things together, including going to Afghanistan together twice. 

When Heyhoe retired from the army, Treo came along too. He settled in and lived with Heyhoe, his wife Rachel, 42, and their three children Ellie-Anne, 4; Thomas, 12; and Oliver, 10.

You see, Treo was a military service dog and Heyhoe was his handler. While in Afghanistan, Treo used his keen sense of smell to find bombs and improvised explosive devices.

It is believed that the black Labrador saved the lives of dozens of British soldiers, a feat for which he was awarded the Dickin Medal, an award that recognizes the gallantry of military service animals, according to the Sun.

In honor of their friendship, Heyhoe got a tattoo on his calf in remembrance of Treo, who died at 14 in October 2015. The tattoo was made of Treo’s ashes and featured a paw print and an ode to the amazing things Treo was trained to do.

“The tattoo completes me," Heyhoe told the Daily Mail. “People might think it's strange, but Treo was like a son to me, and his death knocked me for six. Over the years we have seen gunfire, death and bomb scares together — I've been lost without him. Now it feels like Treo is by my side — where he's supposed to be.”
