Reverse sneezing isn't particularly linked to vaccinations or to heartworm medication. It is simply irritation of the throat (larynx) due to possible allergies or irritation of the throat from a foreign object. I would recommend monitoring her today to see if the reverse sneezing resolves on its own within 24 hrs. As long as she isn't acting ill, eating, drinking well then its ok to monitor. If the sneezing fits don't seem to be resolving on their own, then its best to contact your vet who will likely recommend a short course of antihistamines to try next. In rare instances, a nasal mite is the underlying cause for unresolved reverse sneezing. I hope that Kona's reverse sneezing fits resolve soon! Best wishes and take care.

Reverse sneezing is generally a benign condition that resolves on its own. It may have an allergic component. If it persists and affects breathing, eating or drinking, then Kona should be examined by your veterinarian.
