Acquired Laryngeal Paralysis in a Dog with Hypothyroidism: A Case Report

Laryngeal paralysis related to hypothyroidism is a rare disorder reported in dogs. A 12 year old, neutered female, Golden Retriever breed dog referred to Ankara University Animal Hospital with a history of dyspnea and gagging after feeding. Routine blood work was not revealed any abnormalities. Decreased levels of total T4 <0.5 µg/dL and Free T4 <0.35µg/dL were remarkable. The exact diagnosis of bilateral laryngeal paralysis confirmed endoscopically. Although laryngeal surgery was planned, the dog unfortunately died due to aspiration of the gastric contents. The current case here reflects a rare case of acquired laryngeal paralysis related to hypothyroidism in a dog.
