Consider seeing a dermatologist for allergy testing (not a mail-in saliva test) for the most accurate results.

PS: In my experience, sprays and OTC stuff, supplements don’t work. You could try a grain-free, potato free food. An elimination diet under the guidance of a vet might help, however if the allergies are environmental, it won’t make much difference, if any.
