Well Lucy hates men in hats too,, but she has been with us since she was 12 weeks old,, never had a problem with abuse or scared for any reason,,, The man we got her from was a biker type,, but he was a big puddytat,, VERY friendly and super with the litter of pups when we were there,,, Nice house,,,,

so,,, with saying that,,, In Lucys case,, I think its just a personal quirk with her and nothing from experience,,, Maybe your dog just happens to like the color of black skin,,,, come to think of it,, do dogs see in color?????
