Spontaneous laryngeal disease in the canine

The Laryngoscope

Abstract

This report describes the type and incidence of spontaneous laryngeal disease in the dog. Signs of laryngeal disease are similar to those in other species. Dogs are usually presented with inspiratory obstructive dyspnea or stridor, since earlier signs are often missed. Severe, congenital abnormalities may occur unrecognized due to neonatal death. Subtle anomalies are seldom presented. Congenital paralysis of the laryngeal musculature has been seen in the Bouvier des Flandres and the Siberian Husky. Laryngeal obstruction occurs commonly in brachycephalic dogs (Bulldog, Boxer, Boston Terrier, Pug, Pikingese). The forshortened nasal cavity and pharynx result in reduced airway space. The result is inspiratory obstruction varying from noisy respiration to severe obstruction with cyanosis and syncope. Everted laryngeal ventricles are most common in these dogs. Mild degrees of ventricular edema are common in small breed dogs with lower respiratory disease and in field-trial Beagles due to voice abuse. Traumatic injuries to the larynx and hyoid apparatus are not rare. Bite wounds from dog fights are the most common cause. Compression fractures are rare, but injuries associated with shearing stresses, due to being shcken by the neck cau...Continue Reading
