On Feb. 19, 1951, an ll-month-old, male, mixed Shepherd dog was admitted to the Stange Memorial Clinic. The history was that the dog had probably been run over by a car. Examination revealed a fracture of the tibia and fibula of the right hind leg. The pulse rate was 240 per minute, and the respiratory rate was 60 per minute. The respirations were rapid, labored and of the abdominal type. When the dog was held in a sitting position, there was some relief from the respiratory distress.
