Others Traveled Through Time and Became Emperors, but I Traveled Through Time and Became a Dog?

Others traveled through time and ascended the throne and became emperor, but I traveled through time and became a black wolf dog in a ruined temple. Just when he was looking for someone to stutter, he was taken into the military camp and was about to be stewed into dog meat soup! Fortunately, the history major has a brain and a dog's nose. I can tell when enemy troops are attacking at night from fifty miles away. Serve as a scout, investigate traitors, enter the court, go from being a wild dog to becoming a prince, even with four legs you can reach the pinnacle of life!
