If you are not happy with what your vet is doing, then I suggest that you find another one. From what I heard it is sometimes hard to find a vet that you are comfortable with and trust. I am having that issue right now. As to reverse sneezing---it's been said that it is associated with a collapsing trachea. I have a 11 yr. old that I am suspicious has CP. Now to find the right vet.
