I heard Sai Baba told one of his followers to feed a black dog as a form of service. Who was this devotee and what was the reason for this instruction?

The provided texts do not contain any account of Maharaj (Sai Baba) instructing a devotee to feed a black dog. However, Chapter 0 does describe a devotee named Kashiram who was advised to feed ants. This advice did not come from Maharaj, but from another saint named Janakidas Baba. Kashiram took this guidance so seriously that he always carried a bundle of powdered sugar for this purpose, which he valued so highly that he fought robbers to protect it.
