Chronic idiopathic pulmonary fibrosis in a West Highland white terrier

A 9-year-old, spayed, female West Highland white terrier was presented with a chronic cough, lethargy, and exercise intolerance. Thoracic radiographic findings were consistent with a marked interstitial lung pattern. Idiopathic pulmonary fibrosis, a disease anecdotally linked to this breed, was diagnosed on postmortem examination.
