Barley has more or less permanently had black 'orrible bits round her nip'nops - if I really scrub at them in the bath, they do reduce, but it is obviously uncomfortable for her ....
Mostly the hind ones rather than the further forward ones ....
She has not been spayed - could this just be sebacious stuff which is just not getting cleared because she has never suckled ?? It does seem to get less obvious as she gets older ....
