Marmalade Duke Winslow, also known as Marmaduke is most commonly known as the clumsy, but lovable Great Dane from a long-running newspaper comic strip. The character has also been adapted into animated and live-action films.
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
