I took my lab to my breeder to get her checked out for an upcoming show and she noticed a small spot on Floss's ear and asked if she had a couple of black hairs. Floss got a peice of gum and mucked herself up a couple of weeks ago so I told my breeder I thought it was dirt. I took her home and went to wash the spot off, and well, it wouldn't wash off. Does anyone will know if this will be a problem for showing? It's just a few hairs and a very small spot.
