Congenital bullous emphysema in a dog: a case report

Abstract
Congenital multilobar bullous emphysema is described in a ten‐week‐old Labrador Retriever bitch. The condition was characterized by progressive dyspnoea and cyanosis. Abdominal respiratory effort was marked but no air movement was heard on auscultation of the chest. Radiographic examination revealed multiple loculated gas densities throughout most lung lobes. The radiographic appearance and pathology are discussed, together with the possible causes.
