Black skin disease

[wwiillaarrdd]

From doing researching on the internet, I think my little dog has Black skin disease. He is about 6 years old. He constantly scratches.  He had fleas about 6 months ago and was treated by the Vet.  Now he is fleas free but has small black patches on the skin between his leg joints and stomach area.  The hair has become thin in these areas also.  The rest of his skin is red and scaly.  I give him oatmeal baths once a week along with an application of hydrocortisone cream,  I also give him Benadryl and Zyrtec every night.  If I don't wash him at least once a week, he develops a sour smell that is really awful.  Nothing I'm doing is working very well.  What do you suggest?

It sounds like yeast (dermatitis) to me.  Our Westie is very sensitive and struggles with the same symptoms.  We manage his diet very carefully, no grain, limited ingredients.  Now on sweet potato and fish kibble, avoiding chicken at this time.  

We shampoo him in a medicated dog shampoo containing ketoconazole at the active yeast fighting ingredient.  

Skin flare up can be an allergic reaction, seems yeast infection can be part of it and that infection has all the symptoms you mention.
