All symptoms +

Causes

Pressure changes in the upper airway caused by stenotic nares, an elongated soft palate, laryngeal paralysis, or everted laryngeal saccules stretch the ligaments that support the laryngeal cartilages. These cartilages gradually collapse inward and block the airway. At this stage any change in the dog's need for air can cause acute respiratory insufficiency and cardiac arrest.

Diagnosis

Information needed.

Treatment

The first step is to surgically correct predisposing factors. If symptoms persist, the dog may benefit from a permanent tracheostomy.

Prevention
