In theory this should be in the game! I'll explain...
A Russian dog living in Stalingrad, could have mistaken a live satchel-charge for a bone, chance is slim, but hey, it's HOS after all. The dog could at the very moment he grabbed the satchel charge with his mouth, have heard a badly running tank. Which could for all the dog knows, have sounded like another angry dog trying to steal his bone from him. The Russian dog following his communist instinct rushes forward mindlessly, and runs towards the stuttering noise. But he discovers that the angry dog is a mere dull chunk of steel, therefore the dog loses interest in the not too great tasting satchel charge and runs off leaving the satchel charge beneath the tank. Needless to say the tank blew up soon after.
This has about as much sense as the MKB42 being in the game so it's valid.
