Leo The Road Rage Dog is a SOMAD character on the Forum 2000 web site. Leo is a Bichon Frise dog that was killed by an evil human. Although not much is known about his past, it is somewhat clear that road rage was a part in his death. Most of the time, Leo's vocabulary is limited to one word - "Yip!" This word is usually repeated, or said at different volumes (font sizes).
However, there are times when Leo will become quite eloquent, mostly when he is lashing out at humans.
