This is likely to be either a bacterial or a mite infection (what is the result of the skin scrape?) and should resolve with long course of antibiotic and specific topical treatment (ointment or shampoo). The antibiotic you veterinarian is given is correct and it is a good choice of treatment. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
