Is this a Soviet "dog mine"? I'm overall curious.
No. It's famous soviet dog Julbars worked in mine-sweeping corps. During the war Julbars found more than 7000 mines and 150 shells. It was the only dog awarded with Medal for Battle Merit. Julbars was wounded at the end of war and can't walk in the Victory Parade of 1945, so Joseph Stalin personally ordered to carry Julbars on his coat. So they did.
