As I told you before, environmental allergies wax and wane. It is impossible for anyone, except a veterinarian that has examined your dog to answer your question.
My posts are getting repetitive as you keep asking the same questions over and over again.
You will not find medical help here or on any other forum.
Go to the vet. Get a diagnosis and see what is recommended.
Peace out.
Ps: Stop it with the over the counter meds.
This is not veterinary advise; consult your veterinarian.
