My dog has an acid attack history when he was an infant. After a prolonged treatment and steroid application he recuperated. He was doing completely fine. He has a spot where no fur came ever. But no sense of itching or any irritation he had ever once he recovered. He was mot much exposed to the sunlight.. Now we have shifted to a place where he enjoys sitting on the roof for a long time. Recently I can see the spot is dried and cracked. He is not itching much but it seems like infection. P.S - this place is very dry in general. Please suggest what to do.
