During WW2 the Russians used starving dogs carrying a pack, they trained them to seek out food attached to the bottom of tanks, when this was completed they had a satchel type charge strapped on their backs with a detonator that would set off the charge as the dogs rushed under the tanks, though they realised the dogs could not really differentiate as to who's tanks to run under.
