I gave him another bath today, and his skin is finally starting to clear up! Now he only has a few nodules on his head, and a few on each shoulder. They're gone from his back and neck, and he's not as flakey anymore. The vet gave me a prescription "lotion", which smells very nice and seems to work pretty well. YAYYYYY my boy's glorious coat is coming bacckkkKKKK!!!!
