Casius Marcellus Coolidge

Casius was one of the most prolific artists in American history. He created such memorable masterpieces as Dogs Playing Poker.

And he was a weredog. Of course.

Those dog paintings were not meant to be jokes. They were portraits. Of actual games. When they were found out they had to be played off as jokes.

Casius was one of the few weredog artists. Most weredogs cannot draw a straight line or draw even stick figures. But there have always been a small number, and are a curiosity to other weredogs.

Van Gogh was a weredog. His madness was due to him getting the illness from staying too long in human form too long and not cycling back to dog phase.
