The word śunaḥ means “of a dog,” and śepa means “tail.” The example is ordinary. However one may try to straighten a dog’s tail, it is never straight but always curved. Śunaḥ śepa is also the name of the second son of Ajīgarta. He was sold to Hariścandra, but he later took shelter of Viśvāmitra, Hariścandra’s enemy, and never left his side.
