Nine Australian soldiers, including Sarbi's trainer, were wounded in the fighting when she was lost.
After the battle there was no sign of the dog, and months of searching failed to find her. Sarbi was officially declared Missing In Action.
An Australian military spokesman said it would probably never be known exactly what had happened to Sarbi in the 14 months she was missing, but the fact that she was in good shape showed she had been cared for by someone.
