I heard Sai Baba told Kashiram to feed a black dog to test his devotion. Is this true, and what happened when he did it?

The provided texts do not mention Sai Baba instructing Kashiram to feed a black dog. Instead, as detailed in Chapter 0, a different saint named Janakidas Baba advised Kashiram to feed sugar to ants. This became a practice so dear to him that he always carried a bundle of powdered sugar for this specific purpose. He valued this practice so highly that he was willing to risk his life to protect this bundle of sugar from robbers who mistakenly believed it contained treasure, demonstrating his deep commitment to the saint's advice.
