Dog yelps in pain when reverse sneezing or barking. What's wrong?

Reverse sneezing refers to the reflex of bringing air into the body to remove irritants in the upper area that lies behind the nostrils. The most common causes for younger dogs include infections, the existence of a cleft palate, or bronchial infections. Another primary cause is the involuntary movement of the hairlike cilia that line the respiratory tract and act to remove foreign matter from the air before it reaches the lungs. This involuntary movement of the hair is medically termed ciliary dyskinesis. The most common causes for older dogs include nasal tumors and dental diseases. Other causes can be mucus irritation, nasal passage obstruction, inflammation, excess nasal discharge or secretion, pneumonia, chronic vomiting, and gastrointestinal disease. Under vaccinated or unvaccinated dogs are at a higher risk of developing infections, which may lead to consistent sneezing. Chronic dental disease can lead to both chronic sneezing and reverse sneezing. I recommend taking Tucker into your vet to see what is causing the reverse sneezing, and how best to treat it.
