A 4-year-old, spayed female, Saint Bernard presented for evaluation of a cough of 2 month's duration and skin lesions of 1-year duration. The cough had changed from dry to productive and was occurring with increasing frequency. Treatment with antibiotics had no effect. Physical examination revealed a productive cough. Thoracic auscultation was normal. Reddened areas of skin with scabs and drainage were found on the ventral abdomen and both hind legs. Temperature, pulse, and respiratory rate were normal. Thoracic radiographs were produced to evaluate the cough.
