A 5-year-old Boxer bitch was readmitted to Stange Memorial Clinic, Oct. 10, 1949. This Boxer had been treated at the Clinic previously, entering April 18, 1949, and being discharged May 5, 1949. At that time she had a history of a persistent cough since January. She had been treated (before entry into the Clinic) with sulfonamides and penicillin, but the coughing did not stop.
