Dog Laryngeal Paralysis: Causes and Management

Laryngeal paralysis is a progressive neurological condition in older large-breed dogs that impairs breathing and significantly affects quality of life.

Key Facts

Laryngeal paralysis involves failure of the arytenoid cartilages to abduct during breathing
Labrador Retrievers and other large breeds are most commonly affected
Idiopathic laryngeal paralysis is often part of a progressive polyneuropathy
Affected dogs show exercise intolerance, voice changes, and respiratory distress, especially in heat
Surgical treatment (unilateral arytenoid lateralization) significantly improves breathing

Welfare Considerations

Laryngeal paralysis causes real respiratory distress, particularly during exertion or in warm weather. Dogs may experience anxiety from difficulty breathing, which worsens the obstruction through a vicious cycle. Quality of life assessment is essential. Surgery carries risks but dramatically improves breathing for most patients. Medical management, exercise restriction, and weight control help unmanaged cases.

What You Can Do

Seek veterinary assessment if your large-breed dog develops a changed bark or breathing difficulties
Avoid exercising affected dogs in heat until managed
Discuss surgical options with a veterinary surgeon specialist
Monitor for aspiration pneumonia, a common post-surgical complication
Consider a feeding position assessment to reduce aspiration risk
