Three years may not be much for a human, but for a dog is an eternity.
This dog does not understand the reasons of why he left, can not understand that he was attending to the call of his country and therefore had to fight thousands of kilometers away.
However, when she recognized him, he could not contain his excitement (and not me).
The feelings of animals never cease to amaze. Moreover it would have made it difficult to think that this bitch could recognize its owner after so long.
