Laryngeal Paralysis in Dogs: Symptoms, Diagnosis, and Effective Treatment

Laryngeal paralysis is a serious condition that compromises the integrity of the larynx, the cartilaginous structure that safeguards the trachea during swallowing. When the laryngeal nerves or muscles fail, the glottis cannot close properly, allowing food or liquid to slip into the airway, potentially leading to aspiration pneumonia.

Key clinical signs include an acute coughing fit, gagging, or a wet “yawning” sound when drinking, especially after a long period of rest. The condition may progress rapidly, so early veterinary assessment is essential.

Diagnostic work‑up typically involves a flexible laryngoscopy under anesthesia to confirm paralysis, and a CT scan may be used to rule out structural lesions.

Treatment options range from conservative management—dietary modifications and anti‑inflammatory medication—to surgical intervention such as a bilateral arytenoid lateralization (surgical “open airway”). The choice depends on the dog’s age, overall health, and severity of symptoms.

Prognosis varies: many dogs recover well after surgery with minimal complications, while those with severe comorbidities may have a guarded outlook. Regular follow‑up and monitoring for signs of respiratory distress remain crucial.
