I heard Sai Baba told a devotee to feed a black dog. Who was it and why?

The provided source texts do not contain any information about Sai Baba instructing a devotee to feed a black dog. This appears to be a misunderstanding. However, Chapter 0 does mention a similar act of charity involving a different saint and animal. A devotee named Kashiram was advised by a saint named Janakidas Baba to feed sugar to ants. Kashiram took this advice so seriously that he always carried a bundle of powdered sugar with him. This bundle was so precious to him that he fought off robbers to protect it, viewing the act of feeding ants as a very important spiritual duty given to him by Janakidas Baba, not Maharaj.
