black dogs were considered more evil..i don't remember the leader of the country..i need to go read the history of Dog again because it is getting all fuzzy in my head, but this ruler decided that dogs were advocates of the devil since they lived on the carrion tossed out of the city..so he ruled they all be destroyed..there was great protest from the sheep herders and such so he changed it to only the black dogs and the dogs with the mark if the devil (the spots above the eyes)..i been meaning to drag that book back out. The same ignorance is attached to black dogs as is to black cats. They are considered meaner and evil. I don't know why people are more drawn to the white, or light colors. but they simply are.
