Who did Sai Baba tell to feed a black dog, and what was the reason for this instruction?

The provided source material does not contain any mention of Sai Baba, or Maharaj, instructing anyone to feed a black dog. There seems to be a misunderstanding. However, Chapter 0 does describe a similar act of charity performed by a devotee named Kashiram. He was advised by a different saint, named Janakidas Baba, to feed sugar to ants. Kashiram took this advice so seriously that he always carried a bundle of powdered sugar for this purpose, and he even risked his life to protect this bundle from robbers, valuing it more than his other possessions.
