Reverse Sneezing in Dogs: Observational Study in 30 Cases.

Area of Science:

• Veterinary Medicine
• Canine Respiratory Health

Background:

• Reverse sneezing (RS) is a frequent veterinary consultation reason.
• Limited clinical information exists regarding RS in dogs.

Purpose of the Study:

• To describe clinical characteristics in a cohort of 30 dogs with RS.
• To identify common signalment, clinical features, diagnostic findings, and outcomes in dogs experiencing RS.

Main Methods:

• Retrospective evaluation of signalment, clinical features, diagnostic tests, diagnoses, and evolution in 30 dogs with RS.
• Analysis of data including dog size, chronicity of RS, co-existing respiratory signs, and physical examination findings.

Main Results:

• Small and toy breeds were overrepresented (77% combined).
• Most cases (60%) had chronic RS (>3 months) with frequent episodes (>1/week).
• Inflammatory airway disorders (57%) were the most common diagnosis, followed by anatomical-functional disorders (27%).

Conclusions:

• RS in dogs, particularly small breeds, often indicates underlying airway issues.
• Persistent RS episodes despite treatment were common (61%).
• RS should be investigated as a potential marker of nasopharyngeal irritation.
