Hello and thank you for your question on Petco Pet Education Center, formerly Petcoach! It is hard to say exactly what is causing the tar like circles on Paddy sight unseen without examining her first, but I can offer some possibilities. One possibility could be is a yeast or fungal infection. These can appear as darker areas, some times in circles and sometimes will have an off putting odor to them. Another possibility is blackheads or also called comadomes. These will go away on their own or you can use a mild benzoyl peroxide cleanser and that can help decrease the incidence of them on the skin. I hope this helps!
