Large, deep-chested dogs, such as the Siberian Husky, are believed to be more susceptible to spontaneous pneumothorax.
There are four main categories of pneumothorax: traumatic, spontaneous, closed, and open. Symptoms vary according to the type of pneumothorax, though some common signs include rapid breathing (tachypnea), difficulty breathing (dyspnea), shallow rapid breathing from the abdomen, and rapid heart rate (tachycardia).
Traumatic pneumothorax occurs when air accumulates in the pleural space and happens due to some sort of severe physical shock or trauma.
Spontaneous pneumothorax may show signs of lung disease. This is due to a non-traumatic cause, and may occur with or without some other lung disease.
Open pneumothorax occurs when there is a defect in the respiratory system, such as a puncture in the chest wall, resulting in contact between the pleural space and the outside atmosphere
Closed pneumothorax is identified as pneumothorax without any respiratory defects.
Traumatic pneumothorax is generally open, while spontaneous pneumothorax is always closed.
Another type of pneumothorax is tension pneumothorax, in which air is transferred into the pleural space during regular inhalation, becoming trapped, and creating a one-way transfer of air into the pleural space.
