The Cliche Shiba Inu

Part I- The Origin.

There was once two brothers named Shiro and Jiro. They were about the same age. Shiro was... bold, to say the least. Shiro was overconfident and charismatic. But he was also very determined. Jiro, on the other hand, was pretty smart. Jiro was nowhere near as outgoing as his brother. Jiro was calm,collected, and calculated. But he easily gives up when odds aren't in his favor. One day, while Shiro and Jiro were watching the news, someone knocked on the door. Jiro opened the door to see a scientist holding a bottle with a liquid. The scientist stated,"Would you like to test my serum?" Jiro thought for a moment, but was interrupted when Shiro jumped up and exclaimed,"We'll try your serum!" Jiro thought to himself,'oh Shiro, always one to jump at opportunities.' Jiro decided he wanted to try the serum. Shiro protested, but in the end Jiro tested the serum. However, when the serum went down his throat, something happened. Jiro was turned into a Shiba Inu! Jiro started barking at the scientists and exclaimed,"What did you put in the serum?!" The scientist got embarrassed and ran away. Shiro stood in shock as Jiro looked at his hands—er—paws. They were both very confused on what just happened...
