My sister made the joke, so I couldn't resist drawing it.------(All sheep have rectangular pupils in real life. A "ram" is a male sheep, and a "ewe" a female, so both Bellwether and Doug would have these eyes.)Technically, Judy had two friends in the beginning of the movie who ALSO had incorrect sheep eyes. The studio did this to help the audience see them stand out as "cute" and "relatable", along with Bellwether.
