Alicia, usually there's an underlying cause to miliary dermatitis. There are a few cases that are of unknown origin. I have never in my life heard anything about being common in neutered males. It's actually just a term to describe the condition of the skin. Usual causes are flea allergies, diet allergies, inhaled allergies, parasites or fungus. If you can get down to the cause of the dermatitis, you can eliminate the use of drugs to clear it up.
