Six cases of recurrent pneumothorax requiring surgical intervention in the dog were reviewed. Radiography was not useful in identifying the source of air leakage. A median sternotomy approach was useful for identifying and removing involved lung tissue. All 6 dogs had microscopic evidence of bullous emphysema. Bronchiolitis, thickened pleura, and bronchiolar smooth muscle hypertrophy also were noticed. Underlying mild obstructive lung disease alone or in combination with a defect in pulmonary collagen probably predisposed these dogs to bullous emphysema and recurrent pneumothorax. Of the 6 dogs, 3 survived for at least 2 years after surgery.
