The Emperor's Dog summary:

After an unexpected accident, I was reborn in another world. Could I be the emperor's daughter? Or perhaps a duke's daughter? With a heart full of anticipation, I opened my eyes, and what I saw before me was... A white, soft puppy's front paw. Given this situation, I need to find a way to survive. The only thing possible with this small, insignificant puppy body is... The path of a lapdog, cozying up to those in power!
