It’s one thing to feed your dog honey with local pollens, but it’s another to find one that has pollens your dog is actually allergic to. In theory, yes this can help, but without knowing the pollen content/concentration it is difficult to dose correctly.
What you are trying to do, and what you really want, is sublingual immunotherapy (SLIT) – building up tolerance to allergens by introducing them slowly over time. SLIT does have research, particularly with humans, to back it up: http://www.allergychoices.com/Physicians/Research/Bibliography/default.aspx
You can have your dog allergy tested and get a custom formula of allergens made for you. One company that does this is Heska – http://www.heska.com/Products/ALLERCEPT/Allercept-Drops.aspx
There are non-custom formulas available, based on regional allergens as well. Even products labeled for children (alcohol free) are fine if the rest of the ingredients are dog-safe.
