laryngeal paralysis

In most cases, the cause of laryngeal paralysis is unknown or idiopathic.

Recent studies have found that many dogs with laryngeal paralysis have decreased motility of their esophagus.

Laryngeal paralysis is fairly common in large breed dogs and is rarely found in cats.

Laryngeal paralysis can be unilateral or bilateral depending upon dysfunction of one or both arytenoid cartilages.

I have seen several horses develop to be roarers or whistlers i.e. develop laryngeal paralysis as a result of strangles.

Health issues in the breed are mainly genetic, such as seizures and defects of the eye (juvenile cataracts, corneal dystrophy, canine glaucoma and progressive retinal atrophy) and congenital laryngeal paralysis.

Laryngeal paralysis may also be congenital in some breeds (e.g. Bouvier des Flandres, Dalmatians, Siberian huskies, and bulldogs), appearing in dogs between two and six months of age.

Laryngeal paralysis in animals is a condition in which the nerves and muscles that control the movements of one or both arytenoid cartilages of the larynx cease to function, and instead of opening during inspiration and closing during swallowing, the arytenoids remain stationary in a somewhat neutral position.
