Laryngeal Paralysis in Dogs and Cats

Common info

Laryngeal Paralysis is a condition when the nerves and muscles responsible for larynx cartilage control do not function properly. Muscles attached to the larynx will normally allow the cartilage to open when breathing and close while swallowing. The disease having a disorder in this area may affect the airway and cause suffocation while eating. The common symptoms of laryngeal paralysis in dogs and cats include panting, change in barking character and noisy respiration and breathing difficulty, etc.


Laryngeal paralysis in dogs and cats is an effect of the congenital. In some cases, as a result of injury or tumor development in any area from throats to chests. Moreover, several kinds of disease, such as Endocrinology or the diseases related to hormone disorder, hypothyroidism and Cushing syndrome or disease caused by stress, can also play an important role in laryngeal Paralysis development.


The larynx composes of several box-like sets of cartilage that are under the control of neck muscles. Should this muscle nerve be weakened or paralyzed, muscles will be relaxed, disabling the larynx to function normally.
