Fang, also known as CONTROL Agent K-13, is a supporting character of the first few seasons of Get Smart.
An animal agent, Fang is generally a good dog - though not the best agent, possibly because of how close he was to Maxwell Smart.
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.)
