"In most settings calling any dog 'ugly' is considered rude and cruel. However, at California's Sonoma County Fair, it is encouraged and even applauded." C'mon. the dogs don't care and the people like it, so its not like an insult or anything.

Maybe because White can be a very bright color, yet black is dark so it confuses the flies into thinking it may be something else, being that flies have thousands of tiny eyes. it could also be that the hair/fur is so low, that the flies would be in the open when attacking, and they'd show on the white thus letting others see them.
