Does he smell odd -- like sweaty socks? I'm wondering if it's as a systemic yeast infection. Is that something the vet already tested and ruled out?
The reason I wonder is this: with several fosters, a vet told me itchy, black patches of skin and stinky smell was a yeast infection on the skin. On the vet's recommendation, a bottle of medicated shampoo like KetaChlor (chlorhexadene/ketoconazole) has worked wonders for several dogs (we often have to shampoo every few days for a while). It's a cheap solution too.
