Anything that helps skin quality and repair helps with environmental allergies. I’m sure you know that avoiding all grain is necessary for the storage mite issue, but did you know that putting a couple drops of neem oil, clove oil, lemon oil, or any of the others that naturally repel bugs, in a sprayer of water for dusting helps with dust mites? Never dry dust, always use a damp rag, so the dust doesn’t get in the air.
If your dog was having allergies to pollen producing plants, I would definitely recommend feeding bee pollen granules, but I don’t know if they would be any help in your case.
