Laryngeal paralysis is a progressive condition in which the cartilages of the larynx fail to open during breathing, causing respiratory distress, exercise intolerance, and potentially fatal airway obstruction, particularly in older large-breed dogs.
Laryngeal paralysis causes progressive respiratory distress that significantly impacts quality of life. Affected dogs often cannot exercise comfortably, overheat rapidly, and experience anxiety from breathing difficulty. Progression can be slow or sudden, with acute crises requiring emergency care. Surgical treatment substantially improves breathing and quality of life for most dogs, though the aspiration pneumonia risk requires ongoing owner vigilance. Dogs in warm climates or hot weather require careful management to prevent crisis. Recognising early signs — subtle voice change, exercise intolerance, increased panting noise — allows intervention before life-threatening episodes occur. Owners of affected breeds should be proactive in seeking veterinary assessment for respiratory changes.
