I recommend "Rebirth: A Dog's Enlightenment". This is a Xianxia-modern cultivation novel written by the author, Sword Breaks the Setting Sun. The protagonist Gou Sheng was reborn as a dog. He wanted to live a different life, but fate had made him a purebred Chinese farm dog with a mysterious bloodline. However, in an accident, Gou Sheng discovered that he could speak the human language, so he decided to become a dog and create his own legend. I hope you like this fairy's recommendation. Muah ~😗
