I am not sure if Bentley has seen his Vet for diagnosis yet, but I read this article posted by HDM with some interesting info on yeasty dogs. Maybe you want to reconsider giving Bentley honey due to its sugar content and try bee pollen instead. If he has a yeast condition this could be why you saw initial improvement then nothing; the sugar from honey feeds yeast.
