In-depth guide to laryngeal paralysis in dogs — causes, welfare impacts, and management options.
Laryngeal paralysis causes progressive respiratory compromise that profoundly affects welfare. Early signs include voice change and exercise intolerance. As the condition progresses, even mild exertion causes severe respiratory distress — gasping, cyanosis, and collapse. The fear and physical suffering associated with acute respiratory crises is significant. Hot weather, excitement, and exercise all trigger life-threatening episodes.
The polyneuropathy component means hind limb weakness often accompanies the condition, further limiting mobility and quality of life. Dogs may struggle to rise, navigate stairs, or perform normal activities. The combination of respiratory and mobility impairment significantly reduces wellbeing.
Surgical treatment (unilateral arytenoid lateralisation) dramatically improves airway patency and resolves respiratory distress in most cases. Dogs typically experience immediate and sustained improvement in exercise tolerance and quality of life. The main post-operative risk is aspiration pneumonia, which requires careful management.
