Has she been tested/treated for yeast? That can have a smell. Some dogs, after a major skin issue, will develop yeast afterward bc the skin becomes so out of balance. For example, after a dog is treated for mites/mange...a yeast infection will pretty much always follow. Even though keto can treat yeast...this strain may be more resistant if it's been there for a while. You may want to ask about trying itraconazole next (x30 days).
Also, this kiddo could have a skin bacterial infection concurrently - and that often can be observed via a simple skin scraping and a peek under scope. If she does have mulitiple location bacterial infection, vets will often treat w/ Simplicef x 30 days.
As far as food, it's hard to say...but you could try a novel protein/carb diet/kibble....some recommend Natural Balance. I think it's 'okay', but I don't think that flax has any place in an allergy diet -- so, that ingredient alone is a reason to look for a flax-free allergy diet.
