maybe I´m wrong, but I read long time ago, that it was a big fail, because those dogs were trained with Russian tanks (diesel) and then, when they were used in the real war, most of them didn´t go againts German Tanks (petrol, gasoline) but againts the own russian tanks because dogs learned the smell of diesel xD
Anti-tank dogs were used by the Red Army against the Germans.The dogs were dogs taught to carry explosives to tanks, armored vehicles and other military targets. They were intensively trained by the Soviet and Russian military forces between 1930 and 1996 and used in 1941–1942 against German tanks .
Personally i dont believe they were used that extensively , its too cruel .
