Last month, rescuers from the SPCA in South Africa were alerted to a pair of stray dogs who had been seen huddled alongside a railway line near the city of Durban. When Inspector Lucas Moloi arrived to help, he'd expected to find that both animals had been injured in a train strike.
It turns out, however, that only one of the dogs was hurt. The other, Hero, had simply refused to leave her side.
But he did far more than keep her from feeling alone.
