Listening Patrol

13 Seconds of French listening patrol with dog along the front during the Great War (1914 - 1918). 
Shot of soldier (moustache, beret, jacket, not obviously military - he could be hunting) and very alert German Shepherd (Alsatian) dog. They are sitting together in the snow. The man starts to pick up his rifle. 
Not many film fragments from that period showing a beret this clearly.
