I know it isn't a good comparison, but we have regular "brown" squirrels in our area. Except in our actual neighborhood, that species is pure white, cream, white, red, black, brown with a red tail, red with brown tail, black, black with a red tail etc. There have been albinos but most of the whites have brown, blue or black eyes. This year there is actually what appears to be a true chimera, split down the middle brown/jet black (so far I haven't been fast enough to get a picture). This dog's coat had that same look of red that the "red" squirrels without the dark gene has.
So I'm curious

could be really neat mix too.
