My 16 yr old mixed terrier is taking Prednisone daily (he has a tumor on his snout), thyroid medicine and a liver probiotic. He has deleoped a black residue on his feet. He does stand in our fish pond to get drinks a couple time a day. It is only on his front paws/lower legs. Could this be a fungal or bacterial sin infection? Any suggestions how to treat this. ?
