Juvenile laryngeal paralysis and polyneuropathy is a heritable progressive neurological disease causing welfare impacts from breathing difficulty and generalised weakness in young dogs.
Dogs with JLPP experience progressive deterioration of welfare from multiple concurrent neurological deficits. Laryngeal paralysis causes noisy, laboured breathing and heat intolerance that worsens with any exercise. Concurrent limb weakness impairs mobility and normal activity. Swallowing difficulties increase aspiration pneumonia risk. The combination of breathing difficulty, weakness, and progressive deterioration causes substantial welfare impact. Most affected dogs require euthanasia before reaching adulthood when welfare becomes unacceptable.
