Hello - it sounds to me as though you need to speak to your vet for an appreciation of what treatment is being given and why, and what you can expect from it. There are very few skin diseases looking like this that an antibiotic shot or a steroid shot would 'cure' - is that what a) you were expecting and b) what your vet was expecting to happen when they gave the shot? Good questions from your vet might be, 1) What possibile diagnoses do you think explain these symptoms? 2) which ones have you now ruled out? 3) what could it still be? 4) how do we tell the difference between these possibilities? If your vet doesmt know, it could be that their lab pathologist or a dematology expert could guide them. It could be for example, that the remaining possibilities need eg a biopsy to diagose them,or that another scrape is needed before mites or fungal disease can be ruled out.
