i have a very black dog...puppy actually...so when she has a bit of mucus in corners of her eyes i wipe it off. now i don't like putting my fingers there, germs. but using a wet clean cloth with just water seems ok to do to me ? i don't think it damages her fur around the eyes. just looks a bit obvious on a very black dog so i wipe off. maybe i shouldnt ? maybe i am aggravating the produciton of it by wiping it off ? is a very minor issue i add this...not that worried about it i must say so don't think i am making mountains out of molehills about it.
