In the United States Army,dogs play a vital role,constantly risking their lives,protecting other.They have many skills and abilities that people lack,for example,they use their strong sense of smell to detect mines and bombs.
They are also examples of exceptional friendship with their comrades,which may persist long after its completion.
And this picture,which shows a soldier dozing off at the airport and a faithful dog guarding him is so charming and touching that it became viral,spreading to all social networks.
Someone noticed a vigilant German shepherd guarding his comrade at Indianapolis airport and took a picture.
According to airport employees,they rested at the airport among a group of ten soldiers and two dogs.
This soldier could sleep peacefully,knowing that his devoted guardian looks after him and maybe uses him as a kind of soft blanket.
