My poor dog is suffering from skin disease for almost three months.  My dog keeps on scratching his skin and his skin turns red.  I bought sulfur soap as my friend’s suggestion but no effect.  I have been using the soap for like two months but no effect.  I guess my dog is eating the foods that trigger the itchiness.  If I have extra, I would bring the dog to the veterinary clinic, but I am on a tight budget.  I know that I am being an irresponsible dog owner, I just so wish I have extra.  I tried to do he advice from friends who have a dog though, hoping that it would help, but unfortunately, it didn’t.
