Hi there and thank you for using pet coach to address your concern. From the picture it looks as though it Mau be a cyst that ruptured and dried on the fur. I would have this examined by a veterinarian to ensure there is no infection and to help give you a better answer after physically examining ming to give you the appropriate treatment recommendations. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.
