laryngeal paralysis - PETS
Laryngeal paralysis is a disease that causes difficulty breathing, which may be initially mild and then progressively worsen over time. Most common in older, large-breed dogs, this condition can become a medical emergency. Laryngeal paralysis is a condition that causes dysfunction of the larynx causing reduced ability to breathe deeply and can obstruct the airway.
Understanding the Context
It can be a congenital condition of young dogs or may be due to a neuromuscular disease in older dogs. Laryngeal paralysis (inability to move) results when the muscles of the larynx cannot work correctly, and this means less air reaches the lungs. Being unable to breathe causes anxiety and distress, which can elevate the situation to an emergency or even death. Laryngeal paralysis is a condition in which the muscles that open the larynx/voice box do not function properly.

Can you prevent laryngeal paralysis? Unfortunately, the short answer is no. However, you can manage symptoms to prevent your dog's symptoms from worsening. Laryngeal paralysis occurs when the muscles controlling your dog’s larynx (voice box) become weak or stop functioning properly. Think of it like the vocal cords getting stuck in a partially closed position. Laryngeal paralysis occurs when the vocal folds are unable to abduct (open) in response to exercise or respiratory demands.
There is the only one muscle involved in opening the vocal fold as this is controlled by one of the longest nerves in the body. 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 aspiration and closing during swallowing, the arytenoids remain stationary in a somewhat neutral position. Laryngeal paralysis is a common disease of older dogs, particularly older Labrador Retrievers. The condition was first described in the 1950s and termed “laryngeal paralysis” because the most concerning and obvious aspect of the condition was the dog’s larynx (a.k.a.
