As long as you're going to the vet anyway, you can try asking the vet's opinion as to whether it could be a skin infection. Perhaps he could take a sample to test, just in case. You'll want to hold off on putting oil on the skin till you find out - it can seal the pores & make infection worse. If it's not any kind of infection though, oil on the skin & in the food might help. Oatmeal baths can help a little as well, and there's a product called Humilac for dogs/cats that has gotten pretty popular & many people have said it works well and quickly.
