Laryngeal paralysis is a progressive condition in older large-breed dogs where the cartilages of the larynx no longer abduct normally during breathing, causing exercise intolerance, voice changes, and in severe cases respiratory crisis. Management has been transformed by understanding of Geriatric Onset Laryngeal Paralysis and Polyneuropathy (GOLPP).
Dogs with laryngeal paralysis in hot or humid weather face acute welfare emergencies: excitement or exercise that would normally be manageable causes respiratory crisis with cyanosis and near-asphyxiation. Without surgical intervention, affected dogs live restricted lives with constant respiratory compromise. Post-surgical welfare is excellent in most cases: surgical tie-back provides dramatically improved airway patency, with dogs immediately more comfortable and exercise-tolerant. The welfare challenge of GOLPP is the progressive polyneuropathy that continues after successful laryngeal surgery — dogs develop progressive hindlimb weakness requiring mobility support. Long-term aspiration pneumonia risk requires feeding management including elevated feeding positions and avoiding soft moist food.
