Digs are colorblind!
Dogs, not digs, may be colorblind, My Father is a retired veterinarian and that is the rule.
Whatever, don’t tell me Dogs don’t pick up on ethnicity. I have black friends who have to restrain their dogs when I come to visit; our little 8 pound rat-terrier goes nuts when they visit here, and I lock her in a room. Certainly didn’t train Doggie to be racist, seems to come with the territory.
