Juvenile Laryngeal Paralysis and Polyneuropathy

What are the signs & symptoms that develop in affected dogs?

Due to weakening or paralysis of the laryngeal muscles, puppies often have difficulty breathing during heavy exercise or high stress; this is often accompanied by changes in their bark tone and sound. Affected puppies are also at greater risk of developing aspiration pneumonia. As the disease progresses, hind leg incoordination or weakness often occurs, and can spread to the front legs.

When do signs and symptoms develop?

Puppies affected with JLPP tend to show signs as early as 3 months of age.

How do vets diagnose this condition?

Genetic testing, clinical signs, and sedation to visualize the larynx are all used to diagnose this disorder.

How is this condition treated?

There are surgical corrections that can help dogs affected with laryngeal paralysis. Aspiration pneumonia, however, remains a risk and must be treated aggressively when it does occur.

What actions should I take if my dog is affected?

• Please consult with your veterinarian about the best treatment and monitoring plan.
