Guess the Name

[KitKat023]

I am the oldest of my mom's furkids. I am a 2 year old American Stafforshire Bull Terrier. When I was just a puppy, I tried to chase a parked car, and hurt my nose. My real 1st and middle name is _ _anna Mischeif. But I don't answer to it unless I'm in trouble. They call me _ _ _ _ for short. I like to sleep between my mom and step-dad, and when we go for car rides, I sit in the middle too. One of my little brothers(a cat) can almost say my name. Can you guess what my name is?
