Hi boys and girls my little Yorky has brown spots on his belly I just noticed them yesterday they look like dirt but they will not wash your way. back in February I believe there was a conversation about this topic and I cannot find it there was a sulfur mixture given that could be rubbed on or applied with a paintbrush also no one ever named what this condition is , so if anyone has a name for it , it sure would be appreciated. thank you phillyfred n Niko
