In the Arthurverse, race is a difficult topic. Sometimes it is used synonymously with species, and sometimes it is separate all together. In the universe of Arthur and Elwood, all the characters have a different species (bear, dog, aardvark, cat, human, cow). All characters also have a specific race (white, black, Asian, Native American) that is usually assigned to humans. Sense the Arthurverse is animals living in a human world, everyone has both a race and a species.
It can be hard to tell who is what race, because an individual's species may have a skin color that does not match up with that individual's race. Arthur Read is white, yet his skin color is a light brown because he is an aardvark.
