Perro desaparecido en combate...

... sobrevivió 14 meses en el desierto afgano antes de reintegrarse a su unidad:

A sniffer dog that went missing in action after a battle in Afghanistan has been found safe and well after more than a year in the desert.
Sabi the black Labrador was with a joint Australian-Afghan army patrol when it was ambushed by Taliban militants in September 2008.
Nine soldiers were wounded in the ensuing gun battle, which earned one Australian SAS trooper the country's highest bravery award.
But there was no sign of the bomb-sniffing dog after the battle in a remote area of Uruzgan province.
Sabi's handlers spent months scouring the desert looking for the four-year-old animal, but to no avail.
Last week - 14 months after she disappeared - a U.S. serviceman spotted a dog with an Afghan man at an isolated patrol base in another part of Uruzgan.
