Larynx paralysis is the inability of arytenoid cartilages to abduct during inspiration, creating obstruction of the anterior airways. It can occur unilaterally or bilaterally. They usually affect more dogs than cats, older animals from large to giant, and may appear in small breeds. Males are more affected than females, being quite common in breeds such as: Labrador, Golden Retriever, Flanders Cowboy, Siberian Husky and Alaskan Malamute. Complex polyneuropathy with laryngeal paralysis has been reported in Rottweiler, Dalmatian and Pyrenean Mountain Dog. There are several causes of paralysis, among them the most common is idiopathic laryngeal paralysis, the other forms are hereditary and acquired. The animals present several clinical signs related to respiration: respiratory discomfort, respiratory stridor, cyanosis, cough and dysphonia.
