You were a German shepherd dog, Brutus to be exact, Brutus from pixie and Brutus comics, pixie doesn't exist tho, you were a ex-war dog who had a scar on his right eye and was cold and gruff.

One day, someone moved In the house beside yours, the girl had a dog, lilly, a German shepherd like you, but she was very energetic and not a ex-war dog like you were, she was playful and freindly.
