I can't tank you enough. What a terrible feeling to see that color and fearing it wasn't removable. What is black rage? Is that an acceptable thing to use on a show dog? Is it supposed to make them black? There used to be stuff I haven't seen around in a long time, made to enhance human gray hair--silkn'silver something or other. I would have thought that would be something to try on a dog to get the silver a little darker or bluish. Thanks again, Belinda
