There's what looks like black dirt under Taco's chin. At first, we tried to wipe it off with a damp cloth but that didn't work. Then we thought it may be flea dirt, so we used stronghold on him. It's still there and i'm at a loss as to what it is.
Molly had a simular situation a couple of months ago, we used stronghold on her and the dirt dissapeared, her chin hasn't got any 'dirt' on it anymore.
Anyone know what it may be?
