Successful treatment of regional enteritis in a dog.

Regional enteritis was diagnosed in an 11-year-old, spayed female German shepherd dog with a history of intermittent vomiting and anorexia. Segmental, transmural granulomatous enteritis involved the pylorus, jejunum, and ileum. The jejunal lesions were excised. The remaining lesions completely resolved subsequent to long-term prednisone and sulfasalazine therapy.
