O.k my corgi Toby is has some sort of skin problem on his nose and inside is ears. Its kind of scabby it doesn't seem to bother him but i took him to the vet to get it checked out.. the vet was no help.. she took some skin samples to see if i was mange and she confirmed that it was not that. So she took a few more skin samples and said she would test them for ringworm's and to bring him back in ten days to see the results, she also gave me some pills to give him, they seem to work a little bit but its still red and scabby on his nose not so much on his ears anymore. Does anybody know what this can be?
